Thank you!!!! My system was blowing warm air intermittently at stops but mostly blowing cold again when driving, during a tire repair I had Firestone perform a $9.99 AC performance check, got the car back blowing warm air all constantly, manger tells me I brought in with a malfunctioning compressor clutch and it just died the day I brought it in convientiently the same day he quoted me $1200 for a new one!!! I asked what they did during their AC performance check and was told just checked the functioning of the compressor's clutch via an electrical test, this video is VERY INFORMATIVE for what they should have/could have done to make my car start blowing warm air. I'm a single mom and they're trying to take me to the bank, I'm going higher at Firestone or I'm getting a second opinion about a my AC system in my 2011 Kia Optima before I pay anyone a dime for a new compressor. I am madder than a wet hen!!!
Thank you so very much for passing this valuable info along to people like me who didn’t have a clue. And back in early 2000s the internet still wasn’t what it was then, like it is today.. vast knowledge just by pointing and clicking.
Went to an aircon service and it took them 10 minutes to tell me my compressors is shot,I did have a blown fuse and replaced it before I took it there,never ever refilled the aircon since the car was bought but will go through the stages of advice you've shown me in the video. Thanks for the advice.
This video just proved I don't have a blower motor problem. As a matter of fact all I need is freon.I went thru step by step with another mechanic. Blower motor just blowing real loud and good.
First off, love the channel, and your easy to understand repairs and methods. THANK YOU AND KEEP THEM COMING. My 2002 Merc Benz S430 (W220) A/C stopped working after I replaced the windshield wiper hose (with the heater wire/ cable inside). The unit small red light is on indicating the system works, but will not blow cold air. The clutch does engage, on then off, constantly. The typical reset feature/ trick doesn't work for whatever this error is currently. I checked the relays/ switched and replaced them as well. Assuming the system may have been low on refrigerant, I filled it with what it took in, which appeared to be almost two full "tall" cans of AC Pro. Reset the system and the air came on "absolutely freezing cold" for about two minutes then shut off again. After resetting and attempting to make it stay on, it wouldn't reset anymore after four attempts. I noticed a clear liquid had leaked from the bottom center of the car down the driveway to the rear of the car, no smell or color, but thicker than water. The next day, with the engine running and the air refilled and reset once more, I heard a loud hissing and bursting flow of air or spray from under the hood, front drivers side for about 40 seconds then stopped. I believe it was a pressure relief vale of some sort !!! Scared the &%$#@^& %$#%^&%#@ out of me to be exact. The clutch still engages, on then off, constantly. Whats wrong with the cars AC ????? What would you recommend I check or replace???? No AC for the past four months now...
Hey thanks so much for watching! So every AC system comes equipped with a physical pressure relief valve on the compressor. Once that pressure is met it bursts and relieves the pressure. Too much refrigerant causes the pressure to be too high causing it to burst. So you need to replace that valve and then vacuum the system down and recharge with refrigerant.
Took my car to AAA Auto Repair Center on Tully Rd in San Jose to repair the air conditioning. They told me that the compressor was bad (which I had already figured out since it had a frozen clutch..couldn't push it in by hand while engine was off). I know compressors cost about $300 but they were going to charge me over $1500 to replace it. Then, later, they called me and said they would have to also replace the receiver drier and that would cost another $400 or so. So, after I went back to pick up the car, I looked under the hood and saw a nice shiny new compressor but couldn't see the receiver drier until I got home. Turns out that the receiver drier is like welded to the side of the condenser and has a plug on the bottom that needs to be removed in order to insert a cloth-like cylindrical shaped tampon-looking "drier" that takes moisture out of the system. That's all they did...and they charged me over $1900. The drier "tampon" can be bought at auto stores for from $15 to $35. And the compressor can be bought for about $300. My car is a 2014 Hyundai Tucson. Once you take off the splash panel under the engine of the car and look up at the bottom of the "condenser", on the driver's side of the vehicle, you can see and access the "receiver drier" plug to remove an then to insert the "tampon". I couldn't drain the coolant into a collector before removing those parts so I had to have all this work done by "professionals". Funny, not, how the government will fine you big bucks if you let the coolant escape which helps contribute to global warming but they have no problem sabotaging gas pipelines like the Nordstream pipeline which belched tons of gas into the atmosphere for many days! It's no wonder we are having high, record, temperatures. Wars don't help either. Same thing happened after WWI and WWII..record high temperatures worldwide! Thanks a lot Putin...you son of a b...!!! Putin needs a "b" to the head!!!

My air conditioner doesn't work but my heater does.the speed switch only works on 4. I noticed the pully on the air-conditioner compressor or moter doesn't spin. One works but one doesnt.this is on a 2002 Mazda protégé. Please help me. I'm retired now and do all the work on my car myself. I'm so grateful for RUclips
What could be the reason for an ac to blow warm air, when the system is filled properly, the clutch is engaging so the compressor is running and the blower fan is blowing like it should. ?? So happens on a 1989 ford e350 with a ford 460 engine. Thanks a lot..
The blend door may be stuck so you're getting warm air from the heater or outside vent air. That should be controlled by a vacuum motor or a wire cable.
I've had a honda fit 09' for 2 years and the air was working fine then this summer it still blows cool but won't get cooler than 70degree, got acpro, check with just the gauge and it is in middle of green n everything is working, do it need alittle freon? Please help
The blower fan quite blower there is a aluminum cooler that there are wire,s going to it that is inside of the vent down by the fan motor what is the name of it ?
I have a 2005 Saturn Vue and my AC only works when I’m driving or at a high rpm, when I stop the air gets warm any ideas as to what it could be, it was recharged and checked for leaks and none was detected
so I just bought a 2005 Chevy equinox, and have an issue I have not been able to find an answer to yet. On the lowest two fan settings the AC light turns on if I press it, but I can't hear the fan at all, which might simply because of how low the setting is. However, if I set my fan to high, or even the speed just below high the air conditioner button will not come on at all, but the fan definitely works at the proper speed. At no time does cold air blow out. I tried to add refrigerant to it, but it doesn't seem to have worked.
Good information, none of it applies to me but good info. I have a 94 Mercury Grand Marquis. It is working great when it is not too hot out or I don’t accelerate hard. It will quit working and not recover. It is common for the AC to work until I shut the car off then not work when I get back in five minutes later. 134 was a little low but still in the functional range. The high pressure connection was leaking. Fixed the fitting and brought pressures to proper level. About 40. Only next thought is to bypass the high pressure switch the next time it quits and see if it works. Any other thoughts?
If you bypass the high pressure switch wouldn't it just keep building pressure till something pops? The high pressure just turns off the clutch when it is high enough.
I have a 2001 Chevy Blazer with a fairly new a/c system, absolutely everything was replaced. Recently, the compressor stops altogether and does not cycle once the vehicle has been ran for about 30 minutes. The a/c works great when it works so I assume the high pressure switch it cutting the compressor off but not sure what the problem could be. Putting gauges on, the static pressure is about 100 psi, slightly higher than what was recommended in this video. When compressor is running, pressures are fine, according to a chart for my specific vehicle. Any help as to why the compressor shuts off when warm/hot would be greatly appreciated.
Wow this nice! Having the same issue right now, and I have already checked a few things mentioned here with no issue but I still can’t charge the system, as soon as I connect a can gauge goes in red and will not drop no matter how long I charge. Still blowing hot. Compressor engage every time, electrical seem to be good. I just don’t want to be ripped off at a shop, any advice!
@@2carpros that's what i thought too but, i have never charged the system since i got the car, it's 2013 Buick Verano, and i remove the air until i saw green on my screw driver. thanks
Hi have a i20 2016 aircon stop blowing cold i had a new compressor vale in but still did not work what can it be then my ac compressor or pressor switch
HI PROBLEM WITH 2009 3I 2.0 ENGINE my ac 10 amp fuse mark (mag) keeps blowing off and the compressor don't work but if I jump the fuse with wire a small wire it works again the compressor .what could be blowing the fuse .any help will be appreciated .
hi there? I have an A4 2014 B8.5 1.8 model TSFI... I have a problem with my aircon. when you switch it on. It blows air, but the air only comes from the underneath vents by the feet and by the windshield vents (sufficient airflow by the way). But NO amount of air flow is coming from the side vents of the dashboard and the middle vents of the dashboard by the radio. what could be wrong? thank you for your suggestion.
Good posting! I am trying to diagnose the problem on my 2011 E350 Mercedes. Sometimes the AC will not start at all, but if I shut off and turn on the car again, it works fine. Any idea what it can be? Thanks.
2008 Toyota Avalon. Had system checked and all good except after the alternator was replaced cold air only comes out the passenger and rear vents. Not warm but definitely not cold comes out the driver's side. We were told it was the blend door and the whole dashboard has to come off to replace it any help is greatly appreciated
Hi, I have a question. What exactly is it when my car does get cool but will not stay cool. It won't even reach the backseat. It fluctuates between cool and hot.
A quick one. I replaced my compressor. It was blowing warm air in the left hand side vents. New compressor works fine except the vents that blow from underneath i.e to cool legs/feet. What could be the problem? They were working before replacement and only the compressor was replaced. Nothing else was touched. Thanks
I have a problem with my 2009 Nissan Sentra The AC goes on but even on max inside the never get cold. The defrost works!!And I also noticed that when I look under the car On the asphalt I don’t see any water!! 😳😱. Thank you ..help I don’t want to get Robbed at the mechanic..
Hei.I have everything working fine, but when the car heats up to 90 degrees, the air conditioner turns off and does not work, and every time I turn it on it turns off, why? Greetings to you
Thank you so much for your vid. Are you perhaps familiar with the issue where the aircon switches on and works for a minute or so and then just switches off ? If you switch it off and on again it will start up and cool nicely but then switch off again after a minute or 2. I have been searching online for hours and hours on end with no joy. Greetings from South Africa.
I have a faulty AC and dont need it and dont want to repair it. It is constantly running, I can't switch it of. Can I dissable it by removing the AC fuse?
Question: at first the ac light would blink 3 times and then over time it stopped blowing cold. Compressor is working, it’s full of freon, the actuators are not clicking so I don’t think it’s that either. The high pass tube is ice cold and sweating so for some reason it’s not blowing the cold air in the cab. Would the tube be clogged?
I have a bit of an odd situation and thought you might shed some light on it. My wife's 01 Kia Rio at this point cannot accept the 22 ounce full recharge despite replacing the expansion valve and filter drier. I can get about 6 oz or so of freon in and the gauges are reading 30 on the low side and 150 on the high and anything above this reading the compressor starts cycling. There is some cooling but it's minimal. Everything else seems fine. My thoughts are a clogged condenser or weak compressor. The compressor readings do seem to react accordingly to the level of freon. Any help would be appreciated.
system is full, a/c clutch engages, never diengages, but puts no load on the engine, like the typical bog from turning on the a/c and it blows hot air, dont know much about a/c systems, was hoping it could be fixed inexpensivly
Good video!!! Nothing much been said about the evaporator. I have a ford expedition 2014 at 60k driven ,a.c. system is not cooling as it used to be have to keep the blower speed knob on 3 .and that was worrying for me. So took the car to diagnostics at ford service centre and he said the evaporator is all clogged . Need to change but cost is too high 1500usd. Any alternate solution . Thanx
Shakgoogle Khalid Labor is the high cost because of it being behind the dash. I have a first generation Sienna and I do not have a cabin air filter on it. I took mine out and cleaned it and completely dried it and put it back and I restored my 39 degrees coming out of vent. Mine was a disaster. It took me an hour to clean this thing. Very delicate like a radiator. New expansion valve and o-rings upon installation.
My AC stop blowing cold air after awhile of running in 80m/hr but it return after resting while no problem if im running below 60m/hr..... my motor and condenser is new. What might be my problem?
Great Video. Thanks. I have a problem with my 2008 Volvo V50 A/C system. The charge seems to be fine but after awhile driving the system will turn off, It seems that if I turn the thermostat all the way down and the fan up high and drive at 70 mph on the freeway it will last longer. My thoughts are that the Low pressure switch is bad or there is moisture in the system clogging the expansion valve. I would like to hear what your thoughts are and a possible solution. Im in Florida and its starting to get hot.
I have an `97 ford ranger 2.3ltr.that has an A/C that when charged.Blows cold air.Then stops.Replaced.Compressor switch.Low side.Installed Dye to find any leak.Haven`t found. Any leak in system.Could it be the high pressure switch?
Hi @2CarPros I have a 2007 Hyundai Tucson, when I start up the AC works fine but after a little while it just do not blow out cold air. I have noticed when I drive on a long stretch where the car is in 5th gear and the ref's are above 3500 than the AC works all the way?
My compressor kicks on and stays on, replace clutch cycling switch it kicked on and off couple times in driveway drove 20 miles and it started staying kicked on again??????
I have a 04 Accord and the air is blowing hot air. When I connected a gauge it read way in to the red zone. I used the AC pro they sell in the auto parts store.
My only car is a 1992 Oldsmobile Royale 88. My mechanic says my car is no spring chicken and never tries to diagnose my ac issues. I'm disabled and I get ssdi. My disability it permanent and I'm on a fixed income. So my mechanic usually gives me a good deal but if he wont try to fix or diagnose it..I dunno what to do
Also my mom owned this car before I did. She said the ac never worked for her and a guy from her past employer tried adding charge but it didn't take from what she said. I'd love to have ac in my car but I'm not capable of being financially set so I'm driving each hot summer day like I got richard Simmons making me sweat to the oldies. Lol. Anyways i want ac but dunno where to go for an affordable price
great vid man. i got a 2004 300m ac seem to work if the car is cool temp but as it warms up vents blow barely cold air. any ideas would be appreciated.
My AC is intermittent. It cools perfectly if I turn the unit off before I turn off my car, if I leave the AC running and turn off my car when I come back and start my car it will only blow hot air. To make it turn on I have to turn off the AC for 10-15 seconds, then turn it back on and the AC will begin to cool again. The pressure recharge kit gauge indicator was in the middle of the yellow, between the green and the red zones. Thanks for any help.
When attach the hose to the low pressure the gauge goes to high pressure (red area). Compressor doesn't engage and blows out warm air. Time for another compressor?
@@Alex-pp7pr I ran a wire from battery post to hot wire on compressor while putting freon an that got it done for me oan there also another component u can used to jump start compressor
Good video but it does not give the complete Diagnostics my compressor works, my AC is full, my valve cover went bad but it was reading turn off AC due to high temperature all of a sudden it stopped blowing cold air, fix the valve cover now still does not blow cold air everything works in the car it's just doesn't blow cold air. Help
2005 350z - High side (98 psi) (calls for w/ amb temp 152-194psi) idle -low side (45psi) (calls for w/ amb temp 29-42psi) idle -Pressures do not change with engine RPM -BLOWS hot air Compressor clutch works, in cabin blowing motor turns on, AC control switches work, all AC fuses and relays work. -No leaks are found using UV light -Compressor does not feel warm to the touch indicating mechanical binding of some sort. -condenser is clean and free of debre -System became hotter and hotter over the course of a week, till it finally blows only hot air. Any ideas? I am literally about to change it all.
Isn't is so frustrating? Doing the same troubleshooting. When these systems go sometimes they just go really bad is my guess. I would suspect the compressor itself is going. When the compressor is running is the vent air cold? As in nice and cold not just cool?
THANKS ! A lot of good info. My Audi A4 2001 has no AC and blows hot, the fan in the enigine doesn't come on either. I ill ry the relay, pressure sensor then the fan clutch, thanks !!!
My a/c will only blow on high. I cannot lower the fan output. If I turn it off while driving the defrost comes on. I can't turn defrost fsn off without turning car off. What part do I need to order?
i have a motorhome that is short cycling every 2 to 5 seconds with low side at 35 to 45 and the high side is the same with ambient temp at 77. would you start out with replacing compressor. thanks
I have a 2006 Buick Rainier and the a/c still works but it has a really hot smell and a light haze of smoke coming from the compressor.Is that probably the clutch that needs replacing?
Hi I’ve got a 01 volvo v70 my ac clutch works when I charge it but it doesn’t blow cold air but when I decrease the pressure in the ac my clutch doesn’t work but my air is cooler what’s could be the issue
I have a question I am hoping you can help me with. I have a 2008 Buick Lacrosse. On a hot day when I turn on the AC the inside blower will come on high and the compressor clutch engages the compressor and the compressor turns fine. Both of the condenser fans also turn on but no cold air. Here is the strange thing. With the gauges both connected there is no difference between the high side and low side even though the compressor is running. When the AC decides to start cooling the pressure all of the sudden change as they should and the AC will work fine for the rest of the day. This is an interment problem. I have 2 guesses on this one the expansion valve is stuck all the way open or 2 for some reason the compressor has a problem. What are your thought on this? Have you ever ran into this type of problem? Thank you in advance.
What would be the cause of an ac system cycling on and off at idle. Ac blows cold once the compressor and fan are running however stops blowing cold air once the cycle ends. Happens every few seconds during idle.
Same issue. Not sure yet. My guess is it could be the thermocouple, it's detecting that the compressor is running too hot. So it's the compressor going or the thermocouple itself. It could also be the pressure sensor and/or under/over charge. Confused yet?
For myself it turned out to be the system being overcharged. I simply used a rag and a flat head and allowed some of the overcharge to be vented. This took a number of times and I kept checking the pressure. Worked perfect after
@@zookinthe6ix461 I don't think I'm overcharged. What's was your static and pressure when compressor engaged? I'm 90 static and around 40psi when running. I think I might actually be able to put 10psi or so more in. My crv is known to need a higher psi. And if it's too low it will also endlessly cycle off.
I have a 2004 Chevy Tahoe LT 5.3L vin Z I changed out my a/c compressor clutch due to not turning. A/C was working fine. 2 months later (now) the compressor is squealing much like a power steering pump does hen low on oil. Question; does the compressor just need oil or replaced? I am sure I will have more questions I would prefer to do the work myself and learn than have some one do it for me.
This is a great question, please ask it on our website for absolutely free www.2carpros.com Over there an automotive expert will be along shortly to help you with diagrams that we can't post here due to RUclips limitations. Thanks for watching!
That's why I'm told you always replace the whole thing, clutch and compressor. It's almost the same price for many cars. Also, you could have low oil in your system which would cause the compressor to go.
I have a 2008 honda civic and none can seem to figure out whats wrong with the ac, the compressor cut on so does the blower fan and component but the second the compressor cuts on i lose all pressure on my l hose, please help could it be the pressure valve ?
What could the the most likely culprit, when you vent temp increases when you are stopped at a red light? I would think maybe the pressure control valve in the compressor, please advise, thank you.
Possibly the cooling blower fan for the condenser isn’t working. While you drive along, it will naturally get enough airflow, when you stop it needs the fan running.
@@mitchellbonomi9309 You realise I mean the separate fan for the condenser? Not the the blower motor you can feel inside the car or the one for the radiator cooling the engine…
@@wheater5 Yes, I realize the condenser fan, My Condenser fan and Radiator fan are one in the same, I don't have a two fan system. This is why I am stumped.
I paid 1500.00 to have evaporator core, heater core and compressor replaced but not blowing that cold like it should be? I'm definitely taking it back , but any other reason? 2008 Nissan Altima

One works but one doesnt.this is on a 2002 Mazda protégé. Please help me. I'm retired now and do all the work on my car myself. I'm so grateful for RUclips
What could be the reason for an ac to blow warm air, when the system is filled properly, the clutch is engaging so the compressor is running and the blower fan is blowing like it should. ??
So happens on a 1989 ford e350 with a ford 460 engine.
Thanks a lot..
Did you figure this out yet
Same issue!
The blend door may be stuck so you're getting warm air from the heater or outside vent air. That should be controlled by a vacuum motor or a wire cable.
I've had a honda fit 09' for 2 years and the air was working fine then this summer it still blows cool but won't get cooler than 70degree, got acpro, check with just the gauge and it is in middle of green n everything is working, do it need alittle freon? Please help
The blower fan quite blower there is a aluminum cooler that there are wire,s going to it that is inside of the vent down by the fan motor what is the name of it ?
I have a 2005 Saturn Vue and my AC only works when I’m driving or at a high rpm, when I stop the air gets warm any ideas as to what it could be, it was recharged and checked for leaks and none was detected
The space inbetween the clutch plate is too wide. Clean with brake cleaner and or put a smaller spacer.
What if all the time air is always hot no matter what and if driving high speeds, warm.air is felt through vebts
@Jack Anderson I did just that, thanks, buddy.
Cabin air filter
so I just bought a 2005 Chevy equinox, and have an issue I have not been able to find an answer to yet. On the lowest two fan settings the AC light turns on if I press it, but I can't hear the fan at all, which might simply because of how low the setting is. However, if I set my fan to high, or even the speed just below high the air conditioner button will not come on at all, but the fan definitely works at the proper speed. At no time does cold air blow out. I tried to add refrigerant to it, but it doesn't seem to have worked.
Good information, none of it applies to me but good info.
I have a 94 Mercury Grand Marquis. It is working great when it is not too hot out or I don’t accelerate hard. It will quit working and not recover. It is common for the AC to work until I shut the car off then not work when I get back in five minutes later. 134 was a little low but still in the functional range. The high pressure connection was leaking. Fixed the fitting and brought pressures to proper level. About 40. Only next thought is to bypass the high pressure switch the next time it quits and see if it works. Any other thoughts?
If you bypass the high pressure switch wouldn't it just keep building pressure till something pops?
The high pressure just turns off the clutch when it is high enough.
Just troubleshooting myself, but would suspect the compressor itself is starting to go, it's pretty old at this point. I think that's my issue.
After having my radiator replaced the a/c was blowing hot air only
What can be the reason for this change?
Thanks guys. Toronto Ontario Canada💕
Get oot! You don't need ac in Canada. Try no car ac in Florida. In August.
I have a 2001 Chevy Blazer with a fairly new a/c system, absolutely everything was replaced. Recently, the compressor stops altogether and does not cycle once the vehicle has been ran for about 30 minutes. The a/c works great when it works so I assume the high pressure switch it cutting the compressor off but not sure what the problem could be. Putting gauges on, the static pressure is about 100 psi, slightly higher than what was recommended in this video. When compressor is running, pressures are fine, according to a chart for my specific vehicle. Any help as to why the compressor shuts off when warm/hot would be greatly appreciated.
Wow this nice! Having the same issue right now, and I have already checked a few things mentioned here with no issue but I still can’t charge the system, as soon as I connect a can gauge goes in red and will not drop no matter how long I charge. Still blowing hot.
Compressor engage every time, electrical seem to be good. I just don’t want to be ripped off at a shop, any advice!
You have too much refrigerant in the system. Thanks for watching!
@@2carpros that's what i thought too but, i have never charged the system since i got the car, it's 2013 Buick Verano, and i remove the air until i saw green on my screw driver. thanks
Hi have a i20 2016 aircon stop blowing cold i had a new compressor vale in but still did not work what can it be then my ac compressor or pressor switch
you guys are the best. saved me $300!!
Nice! Thanks so much for watching!
so in formative... mannnnn thanks... Awesome Sauceeee....
Thank you for watching!
I had mine looked at was told one of the hose has a leak...what do i do to fix that?
For it was showing 86 psi whish is way to high I replaced cabin air filter and check the the compressor and checked if the fans were running
HI PROBLEM WITH 2009 3I 2.0 ENGINE my ac 10 amp fuse mark (mag) keeps blowing off
and the compressor don't work but if I jump the fuse with wire a small wire it works again the compressor .what could be blowing the fuse .any help will be appreciated .
hi there? I have an A4 2014 B8.5 1.8 model TSFI... I have a problem with my aircon. when you switch it on. It blows air, but the air only comes from the underneath vents by the feet and by the windshield vents (sufficient airflow by the way). But NO amount of air flow is coming from the side vents of the dashboard and the middle vents of the dashboard by the radio. what could be wrong? thank you for your suggestion.
Good posting! I am trying to diagnose the problem on my 2011 E350 Mercedes. Sometimes the AC will not start at all, but if I shut off and turn on the car again, it works fine. Any idea what it can be? Thanks.
Sounds like the AC compressor is going out. Thanks for watching!
2008 Toyota Avalon. Had system checked and all good except after the alternator was replaced cold air only comes out the passenger and rear vents. Not warm but definitely not cold comes out the driver's side. We were told it was the blend door and the whole dashboard has to come off to replace it any help is greatly appreciated
Hi, I have a question. What exactly is it when my car does get cool but will not stay cool. It won't even reach the backseat. It fluctuates between cool and hot.
A quick one. I replaced my compressor. It was blowing warm air in the left hand side vents. New compressor works fine except the vents that blow from underneath i.e to cool legs/feet. What could be the problem? They were working before replacement and only the compressor was replaced. Nothing else was touched. Thanks
Sounds like a blend door actuator has gone bad. Thanks for watching!
@@2carpros Thank you
I have a problem with my 2009 Nissan Sentra The AC goes on but even on max inside the never get cold. The defrost works!!And I also noticed that when I look under the car On the asphalt I don’t see any water!! 😳😱. Thank you ..help I don’t want to get Robbed at the mechanic..
Hei.I have everything working fine, but when the car heats up to 90 degrees, the air conditioner turns off and does not work, and every time I turn it on it turns off, why?
Greetings to you
Thank you so much for your vid. Are you perhaps familiar with the issue where the aircon switches on and works for a minute or so and then just switches off ? If you switch it off and on again it will start up and cool nicely but then switch off again after a minute or 2. I have been searching online for hours and hours on end with no joy. Greetings from South Africa.
Still waiting for the info for the German auto type of compressor without the clutch.
I have a faulty AC and dont need it and dont want to repair it. It is constantly running, I can't switch it of. Can I dissable it by removing the AC fuse?
Yeah that would work. Or you can just unplug the pressure switch on the low side. Thanks for watching!
This video helped me immensely!!! Thank you!
You're so welcome!
Thank you, saved me a ton of money.
Thanks for watching!
Question: at first the ac light would blink 3 times and then over time it stopped blowing cold. Compressor is working, it’s full of freon, the actuators are not clicking so I don’t think it’s that either. The high pass tube is ice cold and sweating so for some reason it’s not blowing the cold air in the cab. Would the tube be clogged?
Maybe the blender actuator is broken so it's not blowing air through the evaporator. Thanks for watching Scott!
Very informative ty
I have a bit of an odd situation and thought you might shed some light on it. My wife's 01 Kia Rio at this point cannot accept the 22 ounce full recharge despite replacing the expansion valve and filter drier. I can get about 6 oz or so of freon in and the gauges are reading 30 on the low side and 150 on the high and anything above this reading the compressor starts cycling. There is some cooling but it's minimal. Everything else seems fine. My thoughts are a clogged condenser or weak compressor. The compressor readings do seem to react accordingly to the level of freon. Any help would be appreciated.
good video, thanks for the guide
No problem!
Spunk almighty!!! That was thorough.
Gotta be! Thanks for watching!
system is full, a/c clutch engages, never diengages, but puts no load on the engine, like the typical bog from turning on the a/c and it blows hot air, dont know much about a/c systems, was hoping it could be fixed inexpensivly
Did you find out about the problem?..
Because I do have the same problem on GMC terrain.
thermostat
So that's what it is?.
fixed now, compressor was shot, wasnt compressing anything
So.... Did you changed the compressor?. O what did you do to fixed?. Thanks for answering!.
Good video!!!
Nothing much been said about the evaporator.
I have a ford expedition 2014 at 60k driven ,a.c. system is not cooling as it used to be have to keep the blower speed knob on 3 .and that was worrying for me.
So took the car to diagnostics at ford service centre and he said the evaporator is all clogged .
Need to change but cost is too high 1500usd.
Any alternate solution . Thanx

How often do you change your cabin air filter?
Shakgoogle Khalid
Labor is the high cost because of it being behind the dash. I have a first generation Sienna and I do not have a cabin air filter on it. I took mine out and cleaned it and completely dried it and put it back and I restored my 39 degrees coming out of vent. Mine was a disaster. It took me an hour to clean this thing. Very delicate like a radiator. New expansion valve and o-rings upon installation.
My AC stop blowing cold air after awhile of running in 80m/hr but it return after resting while no problem if im running below 60m/hr..... my motor and condenser is new. What might be my problem?
How do I check the a.c. pressure switch connector when it has 3 wires black, white, and red?
Great Video. Thanks. I have a problem with my 2008 Volvo V50 A/C system. The charge seems to be fine but after awhile driving the system will turn off, It seems that if I turn the thermostat all the way down and the fan up high and drive at 70 mph on the freeway it will last longer. My thoughts are that the Low pressure switch is bad or there is moisture in the system clogging the expansion valve. I would like to hear what your thoughts are and a possible solution. Im in Florida and its starting to get hot.
I'm having that exact same situation that you are having, did you get your AC issue fixed?
A tech checked out my system and failed to make it work
I have an `97 ford ranger 2.3ltr.that has an A/C that when charged.Blows cold air.Then stops.Replaced.Compressor switch.Low side.Installed Dye to find any leak.Haven`t found. Any leak in system.Could it be the high pressure switch?
Hi, how about if the compressor clutch stays engaged all the time? is there a problem with the ac system. air is cold though. thanks so much =) peace
Pretty good.
If an A/C system is over charged, will the compressor kick on?
no
97 f-150 5.4 a/c clutch not disengaging. new switches put on high side and lo side, so whats next ? and which relay is it in box
Hi @2CarPros I have a 2007 Hyundai Tucson, when I start up the AC works fine but after a little while it just do not blow out cold air. I have noticed when I drive on a long stretch where the car is in 5th gear and the ref's are above 3500 than the AC works all the way?
Check whether fans are working. Otherwise condenser may overheat
thank you @@rejayanath if it is the condenser, do I need to replace it?
When I go to push the button to turn on my ac the light goes out emediatley and the ac will not work any help would be appreciated
My compressor kicks on and stays on, replace clutch cycling switch it kicked on and off couple times in driveway drove 20 miles and it started staying kicked on again??????
I have a 04 Accord and the air is blowing hot air. When I connected a gauge it read way in to the red zone. I used the AC pro they sell in the auto parts store.

Is clutch spinning on compressor?

Good video , but did not say anything about the drier and the evaporater !
My only car is a 1992 Oldsmobile Royale 88. My mechanic says my car is no spring chicken and never tries to diagnose my ac issues. I'm disabled and I get ssdi. My disability it permanent and I'm on a fixed income. So my mechanic usually gives me a good deal but if he wont try to fix or diagnose it..I dunno what to do
Also my mom owned this car before I did. She said the ac never worked for her and a guy from her past employer tried adding charge but it didn't take from what she said. I'd love to have ac in my car but I'm not capable of being financially set so I'm driving each hot summer day like I got richard Simmons making me sweat to the oldies. Lol. Anyways i want ac but dunno where to go for an affordable price
great vid man. i got a 2004 300m ac seem to work if the car is cool temp but as it warms up vents blow barely cold air. any ideas would be appreciated.
The amount of air coming out if the vent low? If so that is the blower motor, which is a really easy replacement. Thanks for watching!
My AC is intermittent. It cools perfectly if I turn the unit off before I turn off my car, if I leave the AC running and turn off my car when I come back and start my car it will only blow hot air. To make it turn on I have to turn off the AC for 10-15 seconds, then turn it back on and the AC will begin to cool again. The pressure recharge kit gauge indicator was in the middle of the yellow, between the green and the red zones. Thanks for any help.
Did you come right with your issue ? I have a similar problem.
When attach the hose to the low pressure the gauge goes to high pressure (red area). Compressor doesn't engage and blows out warm air. Time for another compressor?
Light speed travel
Gotta jump start that compressor
@@blackbaggdeezy I tried to bypass and other tricks bit no dice on the compressor engaging.
@@Alex-pp7pr I ran a wire from battery post to hot wire on compressor while putting freon an that got it done for me oan there also another component u can used to jump start compressor

With what tool do you vacuum down the system?
Good video but it does not give the complete Diagnostics my compressor works, my AC is full, my valve cover went bad but it was reading turn off AC due to high temperature all of a sudden it stopped blowing cold air, fix the valve cover now still does not blow cold air everything works in the car it's just doesn't blow cold air. Help
2005 350z
- High side (98 psi) (calls for w/ amb temp 152-194psi) idle
-low side (45psi) (calls for w/ amb temp 29-42psi) idle
-Pressures do not change with engine RPM
-BLOWS hot air
Compressor clutch works, in cabin blowing motor turns on, AC control switches work, all AC fuses and relays work.
-No leaks are found using UV light
-Compressor does not feel warm to the touch indicating mechanical binding of some sort.
-condenser is clean and free of debre
-System became hotter and hotter over the course of a week, till it finally blows only hot air.
Any ideas? I am literally about to change it all.
Isn't is so frustrating? Doing the same troubleshooting. When these systems go sometimes they just go really bad is my guess. I would suspect the compressor itself is going. When the compressor is running is the vent air cold? As in nice and cold not just cool?
sir what is the reason expansion valve become bad and indication that expansion valve is bad
THANKS ! A lot of good info. My Audi A4 2001 has no AC and blows hot, the fan in the enigine doesn't come on either. I ill ry the relay, pressure sensor then the fan clutch, thanks !!!
Thank you so much for watching!
Mine blows cool air but not cool enough. Help!
My a/c will only blow on high. I cannot lower the fan output. If I turn it off while driving the defrost comes on. I can't turn defrost fsn off without turning car off. What part do I need to order?
i have a motorhome that is short cycling every 2 to 5 seconds with low side at 35 to 45 and the high side is the same with ambient temp at 77. would you start out with replacing compressor. thanks
Too complicated for me 😳 lol
How do you check the dryer to see if it's bad
I have a 2006 Buick Rainier and the a/c still works but it has a really hot smell and a light haze of smoke coming from the compressor.Is that probably the clutch that needs replacing?
Yeah that sounds like it. Thank you for watching!
Hi I’ve got a 01 volvo v70 my ac clutch works when I charge it but it doesn’t blow cold air but when I decrease the pressure in the ac my clutch doesn’t work but my air is cooler what’s could be the issue
I have a question I am hoping you can help me with. I have a 2008 Buick Lacrosse. On a hot day when I turn on the AC the inside blower will come on high and the compressor clutch engages the compressor and the compressor turns fine. Both of the condenser fans also turn on but no cold air. Here is the strange thing. With the gauges both connected there is no difference between the high side and low side even though the compressor is running. When the AC decides to start cooling the pressure all of the sudden change as they should and the AC will work fine for the rest of the day. This is an interment problem. I have 2 guesses on this one the expansion valve is stuck all the way open or 2 for some reason the compressor has a problem. What are your thought on this? Have you ever ran into this type of problem? Thank you in advance.
Wait another 5 years and the problem should resolve by itself.
What would be the cause of an ac system cycling on and off at idle. Ac blows cold once the compressor and fan are running however stops blowing cold air once the cycle ends. Happens every few seconds during idle.
Same issue. Not sure yet. My guess is it could be the thermocouple, it's detecting that the compressor is running too hot. So it's the compressor going or the thermocouple itself. It could also be the pressure sensor and/or under/over charge. Confused yet?
For myself it turned out to be the system being overcharged. I simply used a rag and a flat head and allowed some of the overcharge to be vented. This took a number of times and I kept checking the pressure. Worked perfect after
@@zookinthe6ix461 I don't think I'm overcharged. What's was your static and pressure when compressor engaged? I'm 90 static and around 40psi when running. I think I might actually be able to put 10psi or so more in. My crv is known to need a higher psi. And if it's too low it will also endlessly cycle off.
On my 2000Ford Ranger a/c problem air is coming out the place where you put the freon on the low side how do I fix this without loosing my freon
I have a 2004 Chevy Tahoe LT 5.3L vin Z I changed out my a/c compressor clutch due to not turning. A/C was working fine. 2 months later (now) the compressor is squealing much like a power steering pump does hen low on oil. Question; does the compressor just need oil or replaced? I am sure I will have more questions I would prefer to do the work myself and learn than have some one do it for me.
This is a great question, please ask it on our website for absolutely free www.2carpros.com Over there an automotive expert will be along shortly to help you with diagrams that we can't post here due to RUclips limitations. Thanks for watching!
That's why I'm told you always replace the whole thing, clutch and compressor. It's almost the same price for many cars. Also, you could have low oil in your system which would cause the compressor to go.
Could have a bad idler pulley since it's close to the a/c clutch & compressor.
I have a 2008 honda civic and none can seem to figure out whats wrong with the ac, the compressor cut on so does the blower fan and component but the second the compressor cuts on i lose all pressure on my l hose, please help could it be the pressure valve ?

2014 GMC Sierra SLE my pipes are freezing cold and sweating but hot air blowing through vent, what is my problem?
Sounds like you have a broken blend door actuator. Thanks for watching!
if i overcharged, would the compressor leak clear oil? would the system still hold pressure? because the pressure is holding
What could the the most likely culprit, when you vent temp increases when you are stopped at a red light? I would think maybe the pressure control valve in the compressor, please advise, thank you.
Possibly the cooling blower fan for the condenser isn’t working. While you drive along, it will naturally get enough airflow, when you stop it needs the fan running.
@@wheater5 Cooling fan does work fine.. any other possibilities?
@@mitchellbonomi9309 You realise I mean the separate fan for the condenser? Not the the blower motor you can feel inside the car or the one for the radiator cooling the engine…
@@wheater5 Yes, I realize the condenser fan, My Condenser fan and Radiator fan are one in the same, I don't have a two fan system. This is why I am stumped.
@@mitchellbonomi9309 What type of car is this? The condenser fan should run all the time, but the main engine cooling fan doesn’t need to.
