Right!!!! Teach and Shared Clearly....With NO dumbass music alll loud. Thanks Much RB.
my dad was a mechanic. when he passed, finding an honest mechanic was difficult mainly because i missed my father in more ways than one. he may not have taught me how to check the engine on everything, but unfortunately, for any mechanic after his passing.... they could never compare in my eyes to my dad. :( thanks for your precise and quick video. you have a skill set all of us need and its appreciated. :) a/c is still busted right now, but at least i got some direction. :D blessings
Yes I’m glad u sent me message I try to keep honest 100% and I did lot of videos so easy self doing videos can help ladies and I had success and good messages for females!! No matter how hard I try to be honest no one trusts mechanic!! I had some one tell me to my face that don’t say ur honest ur bullshit to me his bill was 210 front and rear brake pads I did it for $20 cuz he was old customer and friend. What pissed me off was he banged on my table and boom bill went to $490 He crossed the line

Yup straight to the topic!!!
I have a Kia soul 2012. 2.0L and the compressor are leaking a yellow liquid for some time. I've tried to seal it with RTV silicone, but I think is not working. Do you think I need to replace the compressor? This car has only 73 K miles, so why you think is leaking? We are in winter so we don't use it too much for now, but in summer this place will get 105 to 115 degrees.
-- I have a quote to replace it for $ 1700.00
i have a strange situation. 2000 suburban. all my pressure gauges look good. 100 deg temps outside, low side is 55, high around 315. the high pressure side hose is hot, then after the orifice tube the low pressure side is cold (not super cold) and my air is still blowing about 70 deg out the vents. I also manually put the cool/hot blend door in the cold position just to make sure the actuator isnt stuck. any idea what to check next? i dont wanna throw parts at it, and im pretty good at diagnosing.
also the rear ac (separate controls) only blows hot but that symptom is almost alway a clogged expansion valve. ( front system uses orifice tube, rear uses expansion valve)
That low side and high side pressure a way too high .. low side should not be beyond 30psi and higher side pressure should be around 150 to 200psi
Thank you. Rb
Welcome
Brother man love your videos. My 16 Rav 4 was blowing little less cold air when I put a thermometer on the vent I was getting 60 degree F. I went to a local shop he added little more now it’s seems cold. The question is is it okey to add. He didn’t drain anything.
I also have a other question different subject. I recently checked alignment the rear camber is off and they said it’s not adjustable and my car in my understanding can’t be adjusted I heard accident can throw off that which I had a while ago. Please advise brother.
Well if u added and it worked good leave it as it is if it’s working good!!! Other wise I usully recomend do complet ac service recover vaccum and recharge with ac mahcine
@@RBTheMechanic thanks brother.
Hello, I have a 2009 ford escape. It was blowing hot air during the day and cold at night. I realized the condenser fan is not running so I replaced it. However it is still blowing warm air when ambient air is above 85degrees. The compressor only engages at night. During the day, it cycles on and quickly cycles off. Shop said to replace the entire system. What do you think?
Usully this type of issue is caused by low refrigeration which will not make too cool of air and in sun day light u will feel hot but at night it will get cold because u don’t have the heat from sun anyways do ac service completly recover vaccum recharge
My dodge charger is doing this I believe cuz since the temp outside is above 85 more like a 100 and its blowing hot air and in the morning when it's only like 65 it'll blow colder everything is working so I need to kno how to resolve this problem too
@@hershey653 I think u need ac recharge it maybe low on Freon and it will be enough for mild day but hot super hot it wount do much also check ur fans for correct operation
Thx for the reply it was already once recharged and that lasted for about 2 weeks then it turned 100 outside n nothing I'm at the shop now ironically 😔
@@hershey653 check ur low ac line put ac on see if it gets cold or semi cold let me know how it feels then I’ll guide u more
2014 Nissan Altima dual air. That silver line doesn't get cold. My air blows but hot both sides but even hotter on the driver side. Is it low on freon ?
Dose ac compressor come on?
I hope you can help and this maybe a repeat question but I have a 2014 Sentra Sr. I've taking to 2 mechanics on that does foreign cars and the nissan dealership. Last year I explained my ac was going in and out. It would be very cold when driving on highway, then it would only get cool driving on highway. This month once I turned it on since it's been warmer. I get warm air. In March I took it to nissan,explained to get ahead of problem they said it had freon, no codes, and they was getting very cold they used advice to check when it was on. I told them it wouldn't be right bc it's not hot yet and it doesn't work when it warm. Of course they said they ran all diagnostic and I have no ac issues 🙄. As of yesterday there is no cool air coming out. It was cooler outside than in Mt car. It was about 78 low humidity. Anyway in early March I noticed the heat doesn't get hot either. We had a week of cold and me heat only got warm and took forever to defrost my windows. Sorry this is long but I just need some direction to go in. I have successfully watched other tubers and did process of eliminating issues that were apparent, able to go to a shop and say fix this only and problem solved. I will try to feel the bars like you did in the video is there any other advice you can give me. Also, there's no leaks under my car or smells, I have never had any dashboard lights come on. I keep maintenance up on my car. SORRY SO LONG.
I understand stand ur issue how every dealer didn’t tackle the job or diagnose it properly anyways. # 1. Have a good mechanic let them service the system wi try ac machine when they use ac machine they will see how much Freon is recovered from the system and compair the amount with how much it suppose to have if it got correct amount then u can rule out that it’s low… but if it’s didn’t recover the correct amount. Then us issue is low Freon…… that’s number 1 step. By the way. Put ur ac on ad see if the radiator fans come on?? Check it few times some times it will work and some time it will not work. That’s so
Thing u can do ur self this very car u see in this video had bad fan it over heated how ever it will also cause ac not to be cold enough
Thanks so much for responding!!!! and I will do those steps. I truly appreciate it.
2013 Nissan Rogue S - AC dial turned on high, but warm air comes out on drivers side and cool (not cold) on passengers side. Replaced blower fan last year and since it doesn't blow strong- going to take it apart again but thinking blend door actuator on drivers side is bad? System doesn't show any OBD code errors :/
Yeah check the blend door acuator after that I would recommend do ac service low Freon in the system could cause only part of the system to cool
2006 to 2012 *Ford Fusion* and the Air blows cold for just a few seconds and then turns to heat, click the temperature control nob two clicks to the right off the coldest setting and start the car/AC. Some folks have said that turning on the headlights and fog lights on also works. I haven't tried it yet because it is 90 degrees here and I'm leaving my AC on and don't want to mess with anything until fall.
Apparently, there is some service notification about the computer related to all the vehicle cabin functions and controls that is causing this.
That’s confusing but did u check ac Freon pressure
No. But I watched a lot of videos and nothing was matching what was going on. Then I found this. Good enough for now. ruclips.net/user/shortsCq4-fAAQ6Pc?si=mLJbZa_KQe6JSUSF @@RBTheMechanic
I heard you say there are 2 blender motors. So if my ac is cold, and when I up/lower the fan I hear it going mire/less but there isn't air coming out of the vents? Would this be the blender motor for the vents? 2015 rogue

You the man!
Thank u bro!!! Hopefully this video got ur car fixed!!!
@@RBTheMechanic it did my bro thank you so much
Good explanation.
Thank you
My ac system seems to be working but it doesn’t get cold at ALL. When I turn on the heat at night (when it’s cold out) it doesn’t get warm until after about 5-10 minutes of max air+max heat. Would I just need more Freon or will I need to flush it first? If it needs to be flushed would I save more money doing it myself or having a professional do it? I’m a broke college student in AZ’s random hot/cold weather so I’ve been trying to find out the best solution possible.
Well ac issue might be ur system is low on Freon but do it propperly vaccum the system with machine and reserve the system and about heat check ur blend door motor and coolant level before anything else
@@RBTheMechanic hi I have a 2005 Ford E450 shuttle bus rv everything is new ac compresor dryer condenser evaporator and orphice tube lines get cold but temp still around 79 degrees even while running can it be a faulty compressor

Excellent
I have a Nissan 2008 Nissan Rogue it will blow cold when driving only, but I only see one radiator fan working just wondering if the radiator is not being cooled enough since one is only working. I connected a self refill gauge to check the Freon it shows that it is full.
Yeah then u need to recharge the system it might be low on Freon
I have a 2005 accord for months the air only blows hot and I can’t turn it off hope this works it’s freakin summer I die driving to work
Yeah try check Freon pressure and swap out relay. And update me
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?
Very helpful. Thank you!
U welcome
I have. A 2016 Altima .. the air blows but it’s not as cold as it use to be .. when we put it on the recharge thing it’s in the red but when we took some out it got hot so it’s like it have to be in red in order to even blow cool .. u think u may know what’s the problem ?
Recharge the system by using ac machine recover then vaccum it for 20 minutes and recharge it this would be first step it could be low or too high!! Then update me with results
Thanks for the video
Welcome!!
2007 honda Civic. A/c stopped blowing cold air. Compressor engages, radiator fans turn on, change temperature knob from hot to cold and it changes temperature but not super cold just regular outdoor temperature. Tried to recharge ac but it won't take refrigerant. Seems to have too much pressure. Not sure what to check next.
Check to see if u have pressure Freon it might be low and double check and conform ur compressor engages
Hey friend, did you ever find out what was the causing issue? Thank you - I’m dealing with this with a 2008 Acura TSX, your input would definitely help.
I had hope for this video!
Thank u!!!
Thank you for the video. Ive subscribed! maybe You could advice: 2012 toyota highlander, ac compressor when jumping with paperclip, clutch engages, but it doesnt take freon. I checked fuses,relays, check solenoid( bigger one), its clicking. But it refuses to start taking freon. checked high pressure ac switch.
is the compressor itself?
Thank you very much in advance.
You have to do the Freon service with ac machine recover vaccum and recharge what ur doing will destroy the system it’s prolly over filled too much pressure and will not accept anymore
@@RBTheMechanic thank you for reply. thats the thing,there is no freon in the system. So I jumped it with paperclip, clutch engages, but its not taking freon. Ive noticed, when trying to rotate clutch by hand, when car is off, there is no slight resistance, as it should be usually.
dear i am having a problem with my toyota corolla car ac , in the past it was working ok then the fuses were going bad due to shortage in compressor coil. after changing coil and pully from with a smaller pully , not ac not throwing cold air at all and ac compressor is getting hot. i was advised to change the compressor. as this is getting hot and making back pressure. what do you think on this is all. bcoz my point is the even if the compressor is weak it should make low cooling . buy why not cooling.???
Well U have to change that ac compressor it could be the fault
hi i wanted to ask: what happens if my ac pressure valves don’t have those caps?
It will slowely leak from there not low but sure will also if it start to leak it will go fast some time that valve give up
2002 Ford Focus, green & yellow zone fluctuating pressure per the refill gauge, compressor and clutch come on and off, but no cold air blows because on settings 1,2,3 (not 4) the A/C button will depress and light up, clutch engages, but NO air blows. In Setting 4 the A/C button light goes off, and a brief bit of cold air comes out, then air turns warm.
U might need recharge it may have air pressure
It’s over charged
@@time2shine67 over charge no good u de charge no good
I sold the car. There were several opinions why it blew hot air only.
It was definitely properly charged. But when I put it on AC, setting 4, it would blow only hot air and the AC light went off.
Settings 1-3, compressor cycled on and off. Lines cold. Only warm / hot air.
But at setting 4, AC light would not stay on. It was weird, because on the 1 to 3 settings the AC light would go on, the compressor could cycle, the charge was perfect, but no cold air.
Only warm or even hot air. Frustrating.
At least three or four different people had three or four different opinions about different sensors related to the AC:
blower blend door sensor, air diffuser,
blower sensor, or other door mechanisms? IDK.
etc.
As much as I hate to say it, I gave up.
The car was bought to flip, and I did not make any money on it at all. Lost money. First and last Focus.
It had an even worse "sudden problem" 200 miles after I got it - a head gasket started leaking.
Luckily it wasn't a horrible leak. It only leaked coolant up near the spark plugs. It's an area about 4 inches deep and there's nowhere for fluids to go.
But the coolant doesn't evaporate, and pools in this little area where the four spark plugs pop up on the cylinder head, and coolant pools.
This caused shorting / grounding and corrosion to the top of the plugs. You can take a blower / vacuum and clear all the coolant out of there and the car runs halfway decent for a minute until coolant again starts to leak back in there and causes the same grounding and shorting problems. Coolant does not evaporate, it just boils in that area.
From what I learned this area also tends to leak at the valve gaskets there and oil pools around the spark plugs and causes the same grounding and shorting problems.
Thats how I knew I had gotten cheated. There were records for the plugs and plug wires having been changed just a couple thousand miles previously. Also, for the water pump and some other repairs up there. Clearly the car had overheated. Some repairs have been done. But the head gasket had probably just been patched with some stop leak. For there to be that much corrosion on the newer plugs and plug wires Proved to me that there had been some leaking after the repairs have been done and that's why the car had been sitting for so long and used with such low miles.
I ended up using a product called, "Steel Seal" 🙏
Steel Seal is expensive, but when it's applied correctly / according to the manufactures exact criteria - it can work.
Its liquid glass.
Online videos show Steel Seal being used incorrectly.
Correct is:
Clean all the coolant out,
fill with water,
add Steel Seal,
run at 3,000 rpms for 30 minutes, ensuring system stays full and hot,
then shut off and let cool down.
Product is no longer active once it cools off.
Its Liquid glass and ideally fills the leaking gasket areas if its possible.
Who knows?
It could run for who knows how long.
Worth a try!
I talked to the US Steel Seal rep, and he said "just make sure you do it according to the exact instructions, and let God do the rest."
Cool guy. 🙏 Thanks!
We talked about how the online videos, especially two older ones by Scotty Kilmer, 10 and 12 years old, are both showing incorrect use of the product.
A product called Blue Devil (?) is applied the way Scotty shows.
But, not Steel Seal.
I highly recommend Steel Seal. Be sure you order it from the US Distributor, at Steel Seal USA on Amazon, or else you might get a fake product.
Anyhow, it sealed up and ran good, again.
I changed the plugs, plug wires and sold it at a loss over my investment.
Could've gotten way more for it if the AC was working.
There was a heat wave that month.
No more Ford Focus' for me.
A head gasket repair on those things is very costly, and needs to be done by a professional, in my opinion.
It could've run at least 1500 bucks. I'm not sure those cars are worth spending all that much money on.
But if you're a mechanic I'm pretty sure you could buy and sell those cars because it seems like they all have similar problems.
Let's face it, they're kind of disposable cars after they reach close to 150,000 miles. Very Cheaply made.
Thx for your video and opinions, folks.
thank you for the video, So I am not sure if I catched it or not, but if i turn it to heat and it gets really hot and turn it to cold, but its still warm, what would be the issue? Thank you!
Check to see if ur blend door work
My 18 civic has been making a rattling noise with compressor on since i bought it over two years ago. I had to top off the freon last year a little but it still works good. Dunno if i should bother replacing it or just keep running it

How do you remove system obstructions, old oil, too much oil anything that causes system to not equalize when the compressor is off?
The ac machine can recover most of it
You the man, i was scared but when i went from heat to cold like you said it started bumping out cold
Oh ok
I have a question my fuse box relays for the inside as well engine bay does not even function what can be the issue for that I have a 2016 hyundai elantra se just want to know if it's a electrical issue or just ac because this isn't allow me to.use my a/c it blows hot air
Too big of question ur saying the fuse box has no power but that can’t be every thing else will be shut down. What ru trying to fix? Only ac?

Hello. You really after helpful. Do you have a video on changing a drier for a/c and expansion valve for a/c in 2014 Toyota camry?
No sorry I don’t have video on that usully they don’t go bad
@@RBTheMechanic thank you. Now that makes me wonder if the mechanic is right or not. Basically he said my clutch was not engaging because I didn't have enough freon. He drained and did a recharge with freon but was not getting cold and it was due to the drier that had filter that he said was clogged and that I needed valve changed. But you say it's rare. Now I'm more concerned if that's going to fix it. He said if they didn't get my ac cold, then i needed compressor.
Thanks RB, my sons fit compressor just went out, we replaced with new one ac worked great for about 2 months then hot air, i looked at the ac system and found the ac hoses were covered in either freon or some oil? Do you know if the sealant works then add more freon. I seen two cans of this stuff??
No do not use that stuff try to find where it leaked from repair it … the stuff u add will not work and if it dose work it will jam up orfis tube and other components so avoid that do propper repair
Ok thanks for the info!👍👍

How did u recharge it? Did u use ac machine
Love a man in a uniform😩👀👌
I went t a ac guy with vacuum machine , he vacuum and refill twice because system doesn’t allow to fill all the way , so we finish refill with can Freon , put a manual switch on the clutch relay , so clutch engages , Freon filled , but still no cold air ? What could it be ? The condenser need to be replace ? 2012 Chevy Cruze
U need to still figure out what the issue with system not accepting Freon could be orfis tube
Thank You for the video man. Super helpful. Question, what if that compressor line is still hot?
U need to check if compressor comes on or if the system have Freon pressure
What if the compressor is on already when you start the car? As if it never shuts off? Everything is spinning 😂so I can’t tell if it’s even off when I start the car.
Hi - thanks for the video. I have an issue with my AC and looking for any ideas to fix.
Compressor comes on, belts are ok, clutch engages. Pressure is fine, AC Pro gauge says AC refrigerant is full.
Low side hose doesn’t get cold though.
Does the refrigerant wear out over time???? I’ve had the car 15 years and never had it re-gassed. It just stopped blowing cold this summer.
Thanks
Everything is good ur ac should work how ever that pro gas cans stuff could mess up the system make sure all works lot of people say all work but then somthing dosent. If ac compressor come on clutch engage and it got correct amount Freon ac should and be cold or ur compressor is not building pressure
@@RBTheMechanic hi, thanks for the reply. I didn’t add any gas using cans, just used the kit to test pressure and it said it was already full.
Like you say - everything seems to work but no cold air. Guess it must be some kind of compressor fault or maybe a blockage somewhere?
Thanks
@@CAPR0NA ok I would still do ac service before anything could be faulty pressure I don’t trust those can guages
How was your issue resolved? I'm experiencing the same issue, except when I drive and accelerate there is a hissing sound inside the system. Weeks prior I was hearing sparking in the engine bay. Like I don't know if it was the ac compressor. It was kicking on and off by itself when though I turned the AC off
@@voltixD hi. I never resolved it. All I can think is that there’s a blockage in the system somewhere. Don’t get a lot of hot weather here where I live so I don’t miss it really.
I have 2011 Nissan Altima it’s blowing hot air that’s it. My compressor good and everything but the man telling me that the wire is short with the fuses to the compressor so idk what to do
No wire that's fancy talk , more likely to be a fuse and or relay or metering device like orifice tube or txv metering device; after those are checked still would have to recover the freon and vacuum the system lines and then finally charge the system up .
A realay
Nissan has a common problem on the compressor i have a 2013 Altima and i had the same issue It is the ac compressor solenoid valve It looks like a fancy spark plug and It is a aftermarket part so you have to order It on Amazon or eBay took me 10 minutes and my ac was back working
How did u determine the compressor is good?
Thank you
Welcome!!!
Do you have any advice for a 2015 dodge Durango? I tried recharging it, switched the fuse, added freon but it's still blowing hot air 🙁 it makes a hissing nose when I cut the AC on but its just pulling air from the outside. I'm in Georgia and this summer is brutal
Yes I have advice for you… start with scanning the HVAC system so with high end scan tool see if there’s any codes. Watch my recent video on Toyota Highlander it had code for ac flow sensor $10 part shut the ac system down. So if there are any codes please let me know
@@RBTheMechanic thank you so much for a prompt reply! Is this something I can get scanned for at Auto Zone?
@@victoriakirkland1835 they can scan it free just ask them you want HVAC moduel scanned. And here’s the video of repair I did on Highlander it was small sensor that cut whole ac system down ruclips.net/video/mAwcYQdP--U/видео.htmlsi=qdhrDYSYJ14o52sg
Any idea why the compressor and fans would not turn on ? But the fans kick on too cool the engine down. I also checked the fues and relay and they are fine.
Check ur fuse and Freon pressure to start with if there’s no pressure on system it will not kick on
I have a 2010 centra and I don’t have hot or cold air. I ordered a new blower and it seems to be working fine. The AC like you mentioned is ice cold but no cold air. Any suggestions? I have already checked fuses and everything checked out
Well check ur blower motor it might be bad or resistor try putting it in highest speed
@@RBTheMechanic there is nothing even when I put it on highest setting. Seems strange that I also don’t have heat.
Hi. Please telefon me where its the fuse for butons for ac, for heating....inside the car. My buton dont Work....the fan for engine dont Work...Thank you
What about if the car has a blocked cabin air filter or no cabin air filter and how to check or clean it. If the Evap or Condenser is blocked or if an after market Transmission cooler was added incorrectly and its mounted against the condenser. Is the system charged with R12 R134a or a something else and how the cold and hot lines fill different? I keep looking but no one gives any real answers.
Yeah u can clean the one gotta take it all apart
My pipes were just cold as ice cube now they’re mild I just recharged it so I really have to drain the air to refill the freoon or should I change the relay
Did u use ac machine to do this
2013 Malibu ac stopped blowing cold air, when the day before it was working just fine. Found that the Ac Clutch 10 amp fuse keeps blowing after a few minutes after I turn on Ac. It’ll blow cold air until the fuse blows. All other fuses/ relays are good. Is this an electrical issue or is my compressor bad? Is there anything else I can check before replacing my compressor?
Check the circuit and check Freon pressure could be too much locking up compressor to blow fuse or the compressor clutch coil is bad
Thanks for the help!
Yup u welcome!!!
My truck blows warm. Kinda humid I guess. Compressor kicks on. Pressure drops to about 30 when the clutch kicks on and about 50-60 when off. This was after I recharged from using a vacuum to check for leaks and it held. I did notice neither line gets cold. What should I check for?
Which machine u used to vaccum ? How much Freon did u add and what year make mode u have.
@@RBTheMechanic I can’t remember the name of the vacuum. It connects to my compressor. Let it run for about 45 min. I have an 03 avalanche. Used it on my girls Honda and ram 1500 and those blow cold. It didn’t take the can. Pressure was still up in it.
As I’m typing this, it’s blowing cool , but definitely not cold.
@@arios1977 oh ok so u vaccume and then how many oz did u add. I’m the Freon has to be correct amount can’t be low or too much it will blow hot recheck if u got correct amount it could be compressor not building pressure

It got frosty with that. But the Chevy was maintaining its pressure. About 20-30 when on and about 50-70 when off
@@arios1977 wait can?? That’s the problem can will work if u get lucky other wise it wount work out u need to hook up ac machine and let the ac machine charge the correct amount
Hi I have some ac issues me and a friend just used ac pro on my car, and it had ice cold air for about 2 hours and then nothing could you take a guess as to what you think the problem may be?
It could be that it leaked out… did u try check to see if it go pressure?
@@RBTheMechanic what do you mean 🤔
@@MrMadnessHero when u put r134 in system that means there wasent any due to it had leaked out so when u filled it up it got cold but it was bound to leak out
@@RBTheMechanic Thank you I really appreciate you responding back man
@@MrMadnessHero no problem update me on what u find see if it got pressure if it’s empty then u know it that it got large leak and u can trace it down with using dye I have video on that
hi sir..i have kia soul 2011, my ac dont cool that much, i bring to garage and they said ac compressor need to replace, but the L tube get cold, the L pressure around 45 to 48, the H around 180 t0 200.. already got gas on it, blower is good, do my condenser is dirty? or anything?by the way im in bahrain.
Did u recover and vaccume the system for 20 minutes and then recharge??? It could be low Freon with air pressure which will not cool good… try the service first
I had a new compressor and condenser put on and I'm sweating in my car. This Texas heat is nothing to play with. It will blow cool air not cold for a few minutes then warm air. Can you assist me?
Check your Freon pressure low should read in range of 30-45 psi high side 250 or around. With ac running. It might need reservice with using ac machine need good 20 minutes vaccuming
I have a 2010
Acura TSX and the drivers side blows hot air and the passenger is cold at night it blows out sort of cold could it be low on fuse ?? What should I do
Do a ac service recover vaccum and recharge with using ac machine. It seems to be low on freon
Amazing video and straight to the point, My trucks compressor works and the tube gets ice cube cold but no matter what theres no air, only sometimes. The ac turns on the randomly turns off please help me with what it is
2004 silverado 1500
Check ac pressure could be too high or too low start with that
Maybe the air wheel. It’s usually under glove compartment
My mitsubishi lancer 2011 has not been able to cool for a while now, but heat works. Took it somewhere where they could not figure out anything wrong.. finally taking it in again today since it's summer & the heat is going to be unbearable. When i turn on A/C it does not cool & actually now it smells like gasoline everytime i turn on the system, which cannot be good at all.. they said it has no overheating coolant issues that's "it's fine". The second I change to cold air, it's warm (not hot) & stays that way. 😫
So first thing first can u check to see if ur ac system has Freon pressure? Put on ac and see if ac compressor clutch engages
@@RBTheMechanic thank you i will try this!
Hey I got a 2011 Chrysler 300 limited.ac was blowing hot on passenger side changed blend door now both blowing a tad cooler.checked clutch it's not engaging but I'm able to turn it.so I checked fuse 12 and relay 43 nothing.so I got paperclip jumped relay clutch turns on.psi 111 when clutch was off clutch on 23.so why the hell won't my clutch engage only by jumping it .please help it's getting so dang hot in MPLS
Did u check Freon pressure?
Does repair for blend door actuator cost alot .
I did accord this summer it costed customer about $490 original dealer part. Did Jeep few years back $190 part and labor
So what does it mean if it doesn't blow cold OR hot air, just normal air? I can turn it up to 77 and it's the same temperature air as if I turn it to 68. 2018 Nissan Murano. Thanks!
Ru trying to get heat? If ur trying to get heat it could be low coolant or bad code or u need to bleed the air from the system it dose have processs
I have a 2005 Chevy equinox and the ac system will just blow hot air. All the readings seem to be fine but I’m just at a loss in this 100 degree heat.Any help at all would be appreciated.Currently can’t afford any crazy shop costs.
Check power to ac compressor if all reading is fine and look to see if ac compressor enagages reading can be of hot air pressure instead of refrigeration
@@RBTheMechanic thank you tremendously for the response.I’ll check that this afternoon and if that’s the case I’ll get to getting it replaced as I know it’s a common issue.
My clutch engages, hi side pressure just sits at 75 psi high side. Lines are just ambient temp. What's wrong? Hyundai elantra
Did u do ac reservice
i have a problem.
First ac compressor wasnt running at all so i jumped the sensor and that made the ac compressor spin for a while. i was able to add a bottle of freon while it was spinning but after that it stopped spinning and it wasnt able to blow cold air only warm air. But when i did put the freon in i didnt feel any of the tubes getting cold like it should what could be my problem?
It could be bad ac pressure switch but do check fuses for ac
@@RBTheMechanic yeah that is what i believe is the problem aswell. i have checked fuses and all are good but i do hear some air leaking by the pressure switch so i will have to figure that out aswel
Hello, my friend.. I have this issue... The a/c compressor kicks on and that high line is cool but not cold and the low line is kinda warm. I have a Accumulator as I touch it seems hot and doesn't get cold at all.. It has enough freon.. But inside my truck you can barely feel cool air as it is kinda warm a little.. My compressor does make a slight whining noise... I don't know if I should just replace the whole thing.. The compressor and Accumulator. Let me know if you what you think it may be better to just replace the whole thing.. I was thinking also getting vacuum out and put freon in but might be the same problem..
It might be ur compressor if it’s making noise
@@RBTheMechanic I just went ahead and ordered a compressor and accumulator kit with the oil and high a/c line.. I'll just replace the whole thing call it a day..
Did replacing the compressor solve your problem?
I have an 07 mustang v6. My a/c only last a feew weeks and I have to refill it. All the levels work. Now it doesn’t blow heat whenever I want it to. I want to know what this could be because the a/c works whenever there is freon(doesn’t last long there could be a leak)but it doesn’t blow heat at all.
Use ac uv dye add that in system see where it’s leaking from check out my other lasted ac videos I use ac dye to trace down leaks
@@RBTheMechanic Could a leak caused the heater not to work? Or what could this cause it not to work?
@@rubend.rodriguezjr.530 he is diffrent system u need to check coolelent level check for blend doors working also it could be blocked heatore core
So I checked everything for the a/c on 07 saturn ion and found the Schrader valve is leaking. I used the core removal installer tool but cannot get Schrader valve out. Someone told me that it had to be changed from under the Schrader not from the top and top just go ahead and replace the whole line? Really? Is there a trick to it? Please help it is too hot not to have a/c
I have to check on my system but usully the valve cores come off top normally
I have a 2014 impala and the ac is blowing warm. I noticed that my temperature guage stays on cold when I drive and when I get out of my car recently the blower fans are noticeably blowing now.
U might need to recharge the system it could be low on freon
@@RBTheMechanic ok thnx I'll guve that a try..
I just got my car but it's been sitting, not driven for over a year, and the ac works, heat works, blows really well, but it doesn't blow cold air or barely any, would it just be low on refrigerant or would it be something else?
First thing is the basic check Freon pressure it could be low also replace the cabin filter on these no one changes filter cuz it’s difficult but u have video on it not so bad to do
@@RBTheMechanic thanks 👍
Every time l take my vehicle in for a repair something else needs fixing ugh. I recently had my radiator replaced and now my AC only blows warm air thoughts ?
Well ac is complicated systym start with check Freon pressure and fuse for ac compressor
I have a jeep patriot 2009. The one line gets ice cold. The blend door motor on the dash side looks like it works, is there two of them?
Look like? Or it dose ? Which line get cold low side?
@@RBTheMechanic It does work, I even replaced it. And it’s the low side that gets ice cold
Bro what can you say about my honda civic 2017. Ac not cool enough on idle. Gas no leak after 1 month same pressure. Condenser/radiator fan turns high speed. 40 lowside 200 highside. If i rev 2000rpm it blows very cold.
Some says compressor weak
2017 civic has issue with ac and it has recall on it call ur dealer and ask them.
What would cause it to blow colder on a lower fam setting. If I put mine on high it doesn't blow near as cold as fam on half or below
That’s normal on low fan speed it can get Colder ad the low air take less cooling so it stays colder and cold air comes
@@RBTheMechanic thanks. Figured that might be what it is, or maybe my evaporator is dirty
@@berto371rr no it’s just hot it is when ur fan is low speed it always will throw colder
@@RBTheMechanic ok thank you
I have a 2018 Honda Civic, so I tested it my AC it blows cool on one side but warmer on the other, checked for freon and it has plenty of it. But it’s still not blowing as cold as it should be. Checked the compressor and it kicks on. The change the temperature and from hot to cold and it changed with the dials. What could it possibly be? I’m thinking possible condenser?
I’m not how u checked Freon and it’s plenty only way to check that is to recover it with ac machine and it will measure the ounces how ever u might be checking coolant level u maybe low on Freon or maybe one of the blend doors not working is ur car dual system? It’s good how u figured out the temp changes !!! But do u have dual temp control?
@@RBTheMechanic my friend is a mechanic and he took vacuumed it out, and he showed it to me and it was good, then he filled it up to the capacity. And it still blows warmer than it should be. My car does have a dual system, so it could be one of the blenders. My year has a condenser issue and honda extended it to 10 years unlimited miles. I’m going to take it to the dealer, and for a diagnostic they’re charging $250. If it is the condenser then I don’t have to pay for it because the warranty. It’s just so weird and I live in AZ so it’s starting to get hot as hell outside and inside a hotter car it starts to suck.
@@Raiderlorian93 oh ok so if he did correctly ur good check to see if ac compressor
Clicks on
Im having this same exact problem on my si. Im thinking it could be the expansion valve. I will be changing mine soon. Its in the mail.
@@seven7hsine did u check all the basics Freon pressure ?
mine like that but we put freon and everything but it still didnt work , would i vaccum it? and redo it?
U have to do it correctly use vaccume recover and vacuum and recharge correct

Hello sir. ive been trying to get some answer on my car ac. hope you can help me. I havea Hyundai elantra 2011 and when i turn on my ac the engine is supose to go a bit higher. it doesnt. my ac temp is not cold but cool. My car has only one fan( radiator / condensor) . i know when ac is turned on the fan has to run at high speed, and then it should toggle between high and low depending on the circumstances. My compressor kick in but it doesnt cut off. relays ans fuses are ok. Freon is ok. hope you can help figure this out.Personally i think its the Fan
Seems like ur Freon might be low it will kick on but not make cold try servicing the systym
@@RBTheMechanic thx for your reply. We serviced it. Changed oil .vacumed it. And put new freon in it. But i will check the pressures again today
My a/c gets cold when the compressor is on but sometimes it turns off than stops blowing cold air usuall does it at a stop light or when I’m driving but at idle works fine. Freon is good I checked it with a pressure gauge and fans kick on I have new high and low pressure switch and new compressor. Can it be the condenser? 2002 Escalade
What is ur Freon pressure low and high. Ac on running u said Freon is good only thing I comes to my mind is Freon has to be off level
@@RBTheMechanicI haven’t checked the high side but the low with the truck running is right at 50
For my Nissan Sentra 07, I noticed the AC compressor picks and stop periodically..... It picks and cold normally mostly when I turn off the ignition and start the car up again.... How do you think I can resolve this???
Idk what u mean picks ? U mean kicks on and off
Thank u
Welcome
Thank you very much, great advice!!
Yup welcome!!!
Thx
My AC system gets freezing cold when i tough the lines with AC on. It doesn’t blow cold air just neutral. I changed it to heat and it got hot air quick. I added freeon but it doesn’t seem to stay more than 2min. Idk what the issue could be. All the controls work on center console.

U have to do ac service with ac machine
Q. What if the AC clutch engages for 5 secs then stops spinning? Also, while AC is running, the low pressure AC line is only cool to the touch. I have warm air blowing thru vents inside cab. Any ideas? Low freon level? Faulty AC clutch switch?
Seems like low Freon I would do ac service
@@RBTheMechanic Thanks! I did take my truck to a reputable shop, they performed AC service, pulled a vacuum, held for 10-15 mins w/no loss of pressure, recharged it and now I have cold air blowing thru my vents!! Yeah!!! BTW, over many years, I had taken my truck to AC specialists who insisted that the whole AC system had to be replaced for $1,600 to $2,000! Glad, I passed and said no to them. An honest mechanic is worth his weight in gold.
@@RBTheMechanicwhat if all works, but after new compressor installed, warm air while & after charging freon?
@@mikeprice8307 then not all is working how did u recharge the ac systym?
@@RBTheMechanic I used the analog gauges, & the hand held gauge both with cans
What if the motors not working? Is there a different video for changing the motor?
Blower motor?
I have a 2018 Chevy Impala and when I start the car and turn the AC on, it will work for a while then the AC will stop and start blowing hot air. This has been going on for over a year. What could be the issue?
I would first do ac service some times low or no Freon or hot air pressure can cause this type of issue that is step one. Also after that it could be relay if it got one I know some of these be controlled by computer or ac compressor can cut off as it get hot. But start with refrigerant service
i have a situation as describe in the video, i have pressure on both low and high side, and its consistence, clutch engages, fuse is good, relay is good, ac comes one, condenser has no leaks, took it to a shop, they recharge the ac, and it still warm air coming out, going to check the blend door actuator next.
Did it work?
What is that ? And did that work?
the only comment i can relate to and no answers to be found. smh did you have a look at the actuator?
Got same problem here too
Was is the actuator?
Hi in have element 2006 it doesn’t get cold the Freon is good compressor engage is good ,i checked ice curb replay plus i checked relay with battery test it click click it good but doing heavy raining the a/c works it get real cold after weather get hot a/c cut off and also i drove on high way at night the a/c works that strange so what the trouble ? thank you
Well if I compressor runs then u don’t need to check anything. I would put on ac guages and see if they have good pressure!! Seems like Freon is not enough maybe need servicing
