Great video Danny, a polite suggestion is checking the cabin air filter. I had my Acura's dirty enough to freeze the core and naturally stopped cooling. Swapped it and worked fine.
So a guy was trying to help me and connected the freon can but nothing would go in It seems to me that Honda has the worst air conditioning system ever built. Myself and both of my sons have Honda vehicles with dead air conditioners. It never happened in my Toyota's before
I bought a used Honda 3 months ago that had ac issues. They had to replace the compressor. I also never had any ac issues with Toyota. After this car I'm going back to Toyota.
Hey there my friends I want to tell you that my neighbor was mechanic and he did the so-called Freon recharging and brought it all back to life. So that has changed my opinion so much
@@jamesbondaygeehad my 2010 civic for 10 years now. Did end up having to replace a Freon line once and had to recharge freon about 3 times. But other than that, it's been pretty reliable. Cools just as fast as most modern, newer cats.
can't wait to sit in 48F lmao😁 just diagnosed it using your method and its definitely the expansion valve, although it wouldn't hurt to swap out all the fuses on mine
Thanks U. This is one of the best videos I have seen on diagnosing problems. I am a novice so this was helpful. Couple of suggestions that might seem dumb to experienced follks. CONTROL HEAD TEST: More on codes. What they mean / look like. Point out turn key all the way without starting. ACTUATOR BLENDER TEST: Where located? Engine on or key just turned fully? FAN TESTING: Engine on or key turned all way only? What fans/location A/C RELAY TEST: Show compressor on/off. FREON TEST: Which port? I saw two. Thanks for this fantastic video. Your good teracher adn use a clear voice ❤❤❤
Understood, I plan on going deeper into diagnostic on each code, videos like this take weeks to produce, there’s the research, scripting, then trying to explain in a way that the novice can understand and feel comfortable performing these tests, not to mention with tools that are available for the DIY home mechanic, shooting the video and editing my goal is to have next summer a complete AC diagnostic video, other than this AC video, many of my in-depth wiring diagnostic videos that I spent weeks on haven’t done very well, which tells me my viewers are wanting a quick fix, if not they’re taking it to the shop, the codes are in the description if you haven’t seen them, thanks for your feedback it’s very helpful
@@dannysdiygarage I think few people appreciate how much work goes into making these videos. I followed your process. HEADER TEST: 👎 result is light blinked 4 times. Now I have to figure out what that means AC RELAY: New relay did not engage 👎 🚫compressor (clutch) FAN TEST: ✅ VISUAL INSPECT: ✅ ACTUATOR BLENDER TEST: Don’t know where it is. So unless I can figure out what the 4 blinking lights on header test are I am guessing needs new compressor which probably means whole new system 😢😢😢😢
Thanks for the help Dan, just got a Civic '11 and they said the AC hadn't worked. Parts still spun, bought the relay plugged it in and it worked like a charm!
This saved me an arm and a leg. Had a bad fuse. Which obviously threw off the ac recharge reading. Replaced the fuse, recharged the ac and it works! It isn’t ice cold but it’s getting colder!
Danny help me out. My AC works and the clutch engages and disengages like its supposed to for 10 minutes then it just quits and dont engage again. Does this sound like low freon? I tried recharging it with freon a while back and i tried the fuse swap nothing. Everything else looks fine like u mentioned but i don't know what to do. Should i try to recharge my ac again maybe i didn't do it right??
Great video I had trouble with my 8th generation civic AC cooling properly. It was the actuator motor that controls the air temperature. Once it was replaced with a Honda oem part the problem was solved
My Question is /posible. ..?? Ac compresor not work with out compresor oil?? And GAS QTY? But my car Ac was not working ..my michanic told me you replacement compresor ..vlues and realy. .but I not change compresor vlues and realy........... (I not change anything only compresor oil add little QTY. AND CLEANING COMPRESOR BY PRESHER AND GAS CHANGE. . AFTER MY AC IS WORKING GOOD RESULTS. .. THIS IS RIGHT WAY?? YOU TELL ME YES OR NO ??? (((( IF YOU ENGINEER ))))))
Danny, is there any danger in adding Freon if Freon is not the issue? I suspect that is the issue with mine, but I do not have a thermo to test the before and after. Is there any danger in adding some Freon and then checking if the AC blows cold after? Thanks!
Yes, if you overfill the system it will cause more problems for you. If you're able to,Buy a gauge to test it. Better to be safe than sorry. Ac's are such a blessing and for me A complete necessity. I no longer have a thyroid soo it's no beuno not having AC right now. No one can pin point wtf is wrong with mine so I'm trying to do it myself lol. Ohh ohh get a gauge that shows you BOTH the high and low side! I hope you get it figured out❤
Hello Sir, When i turn on the switch the two buttons has to be pushed before turning on.. and after i turn the key on the first light goes off and AC light never turned on (what’s the problem here) ??? Please suggest
Hi danny, I have a 2008 civic lx. The AC will work when at night time, AC will work for the first 5-10 mins of driving at the hot day then it will start not blowing cold air. What can be the problems there and I have recharge the AC.
Hey Danny. I also have a 2009 Honda Civic Hybrid. I have a digital thermostat temp gauge. When holding down the recirculate and rear defogger for a few seconds my display spelled out AC. My control head does is not change the direction of the air and it’s also hot air and not blowing cold. Any ideas?
check your fans too. both should spin when the acs on. if one dont spin, you dont get enough airflow on hotter days. i just drove home today in 112°f heat and it was enough to make the compressor shut itself off, all cause the stupid condenser fan relay didnt work :(
I had problem with 2007 civic where clutch only engaged sometimes the hotter it got outside the less likely it was to work so we took ac clutch plate off through wheel well it is a common problem and took out one spacer shim washer and cleaned rust from back of clutch plate with wire wheel the few thousands of the shim had it working perfectly after we put it back together and it has worked for years since then
Great video, tha tip of pressing the buttons 1:03 down and turning the ignition helped alleviate some stress, no warning lights. Then I swapped the relays 6:39 as you suggested and it was a dead relay, so I bought a new one and AC is up and running. Thanks Danny.
@@dannysdiygarage When I press the buttons down and turn the ignition, the recycle light flashes. So, what should I do? My 09 civic is blowing warm air even when I turn AC on.
@@dannysdiygarage I further watched to the end of you video and checked again, my actuator blend door does not move at all when I switch cold to hot back and forth. Let me study how it can be fixed.
So I have a little bit of an odd issue. When I bought the car the ac would not blow as cold at an idle but would blow very cold while driving. Now it consistently blows much warmer regardless driving or not. The clutch on the compressor engages. Both fans kick on. And the dummy gauge reads that it has refrigerant in the system. I’m thinking either blend door actuator or possible the expansion valve. I already pulled the cabin filter and cleaned it out.
Hello my Honda civic 2010 blows warm air and doesn’t change the air directions ( fog-front-back-down) can you help me out please it’s my second car and this it the first time it happens
Good sir one thing you didn't mention is sometimes it could be the in cab aii filter behind the glove box, if it's covered in dirt and leaves this will restrict the air flow as well. Awesome video in detail 👌!
Correct me if I’m wrong but when filling the low pressure side are you not supposed to keep the can upright and 45 degrees max to keep liquid from going into the low side? Can’t compress liquid, right?
So my ac was blowing warm on idle but once I would go it would cool down followed this man’s first steps and turned out my cold to heater actuator was just stuck a little before all the way cold flipped it to hit the back to cold and fixed the ac issue lol what an easy fix
How did you fix it exactly? Im having the exact same issue (coolish air blown at idle, alot cooler while moving) my blend door actuator moves when I change the vents from face, to feet, to defrost.. all of that. But it doesn't move at all when I change the temperature from cold to hot, and back and forth. But it does change the temperature.
You completely skipped and didn't address the passenger side blend door and actuator that's behind the glove box that directs air flow to different vents 😶
I think this video needs to add changing out the fuse and relay. That fixed my problem because I saw that the clutch was not engaging when I turned on the A/C. There's no problem with the fan or the system holding pressure.
My 2013 civic just started instantly blowing warm on my way home, went cold for 30 seconds again and back to warm. Owned it for 10 years 110,000 miles and this is the first issue I’ve really had with the car lol. It’s also extremely hot outside right now and one of my suspicions is the system kicks off when it’s too hot.
@@dannysdiygarage not yet, maybe tomorrow actually. What ended up happening was the red 12 volt wire rotted off the electromagnet side of the clutch. It was barely connected, thus an intermittent weak connection and sometimes it would work sometimes not. I ordered a whole new clutch assy with pulley, clutch, electromagnet for $40. The replacement process is straightforward. Compressor doesn’t need to come off, Freon doesn’t need evac or recharge.
My radiator fan works but condenser fan won’t turn on, and my compressor turns on when I hit it with a screw driver, does that mean I should adjust the shim?
possibly, however I would also tap the condenser fan motor to see if it starts working, I show this in my window motor video, or even starter video, its a great way to test motors of any kind, link ruclips.net/video/8B0d4jfwGYk/видео.html
hi danny, i am ajay from india, i have honda civic 2011, my car's dashboard, gear knob area and center rail area getting hot while driving in winters, in summer ac works properly that's why dashboard not getting hot, but in winters i can feel heating while driving,..please help me
I'm not dealing with it, however a trick is before you quit driving (Maybe a mile before you shut the car off) your car shut the ac of, leave the fan motor blowing on high and record button in fresh outside air mode,
3:43 Can anyone please answer this because he doesn't address this in the video. He moved the temperature from cold to heat to middle and the actuator moves. I purchased a new actuator and the new actuator does not move when i move the temp from hot to cold it does not move at all unlike in your video
Is it true that we aren’t supposed to mix R134a and R134? I’m in Canada and my used Civic originally had R134a, and I heard that I’m supposed to flush it first.
Question: 07 Civic EX. A/C wasn't charged when I bought it. I was told it just needed freon. Bought a charge kit from Walmart. Put it on the low pressure side to change it. It was empty. Turned everything on high/max, pulled the trigger, clutch activated but the gauge shot to the red/full/danger zone within 3 secs. I know it's not full. What do you think?
What are your thoughts on hotwiring a switch to my dashboard in order to get my ac running. It’s an old car, ‘96. The ac works, I just can’t get the compressor to engage no matter how many parts I replace. No one can figure it out. I’ve heard of people doing this. I understand that this could kill the compressor, but if I cycle the switch on and off, maybe I could get by. What do you think? Thank you!
I would not do a switch, I would spend more time to diagnose the problem, I don't know what diagnostics you have done, but there is a Thermal protecter in that circuit, should be somewhere left front corner of the engine compartment, two red wires going to it. check that
@@dannysdiygarage. Thank you for your timely response. You give good advice. I was blessed to find a video about my same vehicle with the very same problem. It turned out to be a burned AC control panel. I removed mine today and immediately knew by the smell that I have a bad unit. It was the same odor that I had detected just minutes before it stopped working. I’m getting one cheap tomorrow and it swaps out extremely easily. If by some strange circumstance anyone owns a 1996 Nissan Quest/mercury Villager, and has tried everything without success, just know that the head unit is trouble prone and hard to diagnose because it still functions in every way except for the AC on button which is responsible for engaging the clutch. However, the light illuminates when depressed which makes one believe that the compressor is getting a call to engage but not so. Hopefully this helps someone.
On my 2010 Civic, the air blows warm when I'm at a stop light. Once I start driving again, the air goes back to blowing cold air. Any suggestions? Thanks
@@dannysdiygarage try to add 12a to the civic with 134a freon, some said don't mix, but many said they just add 12a into system with 134a and have no problem even after few years , so should I do this ?
I replaced my clutch and magnet I had the ac running properly for 3 days then started blowing hot air. Freeon was topped up and relay was changed. I. Wondering if it's the expansion valve?
I've got an Honda Civic 2008...the AC stopped when the outside temperature arise more then 40 Celsius degrees. It works for 10 min and then stopped. Also, if I drive my car for 10 min with 40 degrees and try to turn on the Ac doesn't works. Anyone has any idea what it could be?
Danny - I didn't get any codes from the control panel at 2:09 in the video. At 2:26 in this video, the 2nd mode/button from the left on the control panel is NOT working properly. This is the button where there is an arrow pointing to the face and an arrow pointing down to the floor. The light comes on OK, but the air is ONLY coming on at the bottom toward the floor, NOT at the top toward the face. I did notice that if I select the 1st button, with the arrow to the face, and the 3rd button with arrow pointing to the floor separately they both work. What could be the issue?
My 2011 CRV ended up having clutch engagement issues due to wear and tear increasing the spacing between it and the compressor. Removed it and removed a spacing shim to reduce the gap back within spec and now it engages and blows cold!
There are 3 or 4 shims in there of different thickness. The air gap recommended is 0.35mm to 0.65mm (about .014" to .024"). Removed 1 or 2 that give a recommended air gap between the clutch plate and pulley.
Thanks so much for this informative video! I had watched other videos suggesting the A/C clutch relay might be the problem (it was), but I didn't have any way of testing the theory out without ordering the part first. I'm just not knowledgeable enough about cars to randomly try swapping things out and around without worrying I'm going to cause some sort of catastrophic failure, so I rely on people like you to give me the confidence to try this stuff out without worrying that I'm doing something wrong. It was your suggestion to swap the rad fan relay with the A/C relay that helped me pin it down as the definite cause for my A/C issue. So thanks again, I appreciate the work you do!
not sure if you experience this situation I am currently having on my civic aircon.After driving a while longer with AC on turned at the lowest temperature, the ac starts blowing hot air, it literally just heats up instead of just not blowing cold air. with AC on putting it to low temperature cant defog, now I can only use high temperature to defog. It does has compressor clutch engaging all but blow wrong temperature. what component do you think it could go wrong? The ac blows normal cold air varies from different temperature I set, most of the time while the car has been driven like the first 15-20mins after a certain time, that symptom starts.
May i ask y a question with a ac issue. I have a honda 2008 mk8 1.8. I filled the ac up with coulant. I replacement the relay I can hear the ac pomp working. I checked the same wire. I have 1 connection instead of 3, it works. The H intake feels cold but the L intake feels warm. Still the air isnt cool inside the car. What could be the problemen?
Hey so I have a 2010 Lx, mine blows very cold for about 10 minutes then becomes hot, I ran the diagnostic and it blinked 4 times as I’ve also been having trouble with the buttons, could that be the reason my ac is blowing warm also or do I have other issues?
I’m also having an issue with my Honda civic not having ac. A few of my buttons don’t seem to function especially the defrost and no cold air? Anyone have any tips or guesses?
if your fan isn't spinning remove the connector at the fan and see if you have 12 volts and Ground at the connector, if you do, you will most likely need a fan motor. This is just an educated guess, proper diagnostics would prove this, good luck update me on what you find
My issue is the worst one…compressor clutch will not engage even with giving it the love tap that Danny did. A/c relay sway with radiator swap also did not engage the clutch…
Hi Danny thank you. You are a teacher. I changed the relay because the AC was intermittent in my civic 2008 then the odometer cannot be modified and also the AC continue intermittent. Advice please
thanks! I think i'm still gonna go to the rip off garage but at least I understand this stuff better thanks to you. my a/c will get super cold but unfortunately it takes about 1/2 an hour for it to happen and most of my driving is 20 min or even less - doesnt' ssound like long but like you said 90's gets hot quick

possibly, however I would also tap the condenser fan motor to see if it starts working, I show this in my window motor video, or even starter video, its a great way to test motors of any kind, link ruclips.net/video/8B0d4jfwGYk/видео.html
hi danny, i am ajay from india, i have honda civic 2011, my car's dashboard, gear knob area and center rail area getting hot while driving in winters, in summer ac works properly that's why dashboard not getting hot, but in winters i can feel heating while driving,..please help me
I’d love to help, I don’t understand the question
I have a 2012 honda Civic it takes my ac about 20 minutes to get cool but it never gets cold
Lots of things to check out, low Freon most common
Have you dealt with moldy/musty smelling AC? My 9th gen is smelling
I'm not dealing with it, however a trick is before you quit driving (Maybe a mile before you shut the car off) your car shut the ac of, leave the fan motor blowing on high and record button in fresh outside air mode,
freon is ok, relay is ok, new compressor, fuse is ok , still not engage, your solution is not worth
There’s other videos on my channel for different scenarios, I’m also in the process of adding more on ac
3:43 Can anyone please answer this because he doesn't address this in the video. He moved the temperature from cold to heat to middle and the actuator moves. I purchased a new actuator and the new actuator does not move when i move the temp from hot to cold it does not move at all unlike in your video
I’ll be doing a video on that next
Is it true that we aren’t supposed to mix R134a and R134? I’m in Canada and my used Civic originally had R134a, and I heard that I’m supposed to flush it first.
True, not meant to be mixed
@@dannysdiygarage thanks for the advise!!
Question: 07 Civic EX. A/C wasn't charged when I bought it. I was told it just needed freon. Bought a charge kit from Walmart. Put it on the low pressure side to change it. It was empty. Turned everything on high/max, pulled the trigger, clutch activated but the gauge shot to the red/full/danger zone within 3 secs. I know it's not full. What do you think?
many reasons, I could not begin to even guess unless you installed a set of gauges and had reading of both high and low side, sorry
Did you pull system into a vacuum 1st?
What are your thoughts on hotwiring a switch to my dashboard in order to get my ac running. It’s an old car, ‘96. The ac works, I just can’t get the compressor to engage no matter how many parts I replace. No one can figure it out. I’ve heard of people doing this. I understand that this could kill the compressor, but if I cycle the switch on and off, maybe I could get by. What do you think? Thank you!
I would not do a switch, I would spend more time to diagnose the problem, I don't know what diagnostics you have done, but there is a Thermal protecter in that circuit, should be somewhere left front corner of the engine compartment, two red wires going to it. check that
@@dannysdiygarage. Thank you for your timely response. You give good advice. I was blessed to find a video about my same vehicle with the very same problem. It turned out to be a burned AC control panel. I removed mine today and immediately knew by the smell that I have a bad unit. It was the same odor that I had detected just minutes before it stopped working. I’m getting one cheap tomorrow and it swaps out extremely easily. If by some strange circumstance anyone owns a 1996 Nissan Quest/mercury Villager, and has tried everything without success, just know that the head unit is trouble prone and hard to diagnose because it still functions in every way except for the AC on button which is responsible for engaging the clutch. However, the light illuminates when depressed which makes one believe that the compressor is getting a call to engage but not so. Hopefully this helps someone.
On my 2010 Civic, the air blows warm when I'm at a stop light. Once I start driving again, the air goes back to blowing cold air. Any suggestions? Thanks
Probably low on Freon
Also check the fans, I’ll have a video on fans coming out next week
My compessor clutch did engage, i haven't fill the freon yet, if i fill the freon and temperature drop, is that mean there is leaking?
that is correct
@@dannysdiygarage try to add 12a to the civic with 134a freon, some said don't mix, but many said they just add 12a into system with 134a and have no problem even after few years , so should I do this ?
I replaced my clutch and magnet I had the ac running properly for 3 days then started blowing hot air. Freeon was topped up and relay was changed. I. Wondering if it's the expansion valve?
What if it starts flashing codes
I've got an Honda Civic 2008...the AC stopped when the outside temperature arise more then 40 Celsius degrees. It works for 10 min and then stopped. Also, if I drive my car for 10 min with 40 degrees and try to turn on the Ac doesn't works.
Anyone has any idea what it could be?
When the ac stops working go through the diagnostic shown in this video to help pin point where the problem might be
i had this problem and removed a shim washer in the clutch then it engaged properly when it was hot out it was pretty easy fix
My pressure system is messed up and the low side has high pressure and the high side has low pressure
I’m pretty sure mine is too how do we fix this? I’ve never worked on AC
Danny - I didn't get any codes from the control panel at 2:09 in the video. At 2:26 in this video, the 2nd mode/button from the left on the control panel is NOT working properly. This is the button where there is an arrow pointing to the face and an arrow pointing down to the floor. The light comes on OK, but the air is ONLY coming on at the bottom toward the floor, NOT at the top toward the face. I did notice that if I select the 1st button, with the arrow to the face, and the 3rd button with arrow pointing to the floor separately they both work. What could be the issue?
HOLY FUCKIN' FUCK!!!
YOUR "NOT RECOMMENDED" METHOD WORKED FOR MY CAR!😂😢
THANK you so much!
Worked for me..thanks alot...just had to reset
I’ve had my A.C. fixed numerous times. Just last summer at the tune of over 400$. Still blows out mildly cold air. I a m at wit’s end!
My 2011 CRV ended up having clutch engagement issues due to wear and tear increasing the spacing between it and the compressor. Removed it and removed a spacing shim to reduce the gap back within spec and now it engages and blows cold!
Awesome, great information, I appreciate you sharing this👍🏼
There are 3 or 4 shims in there of different thickness.
The air gap recommended is 0.35mm to 0.65mm (about .014" to .024").
Removed 1 or 2 that give a recommended air gap between the clutch plate and pulley.
Great video but no explanation of what's wrong if a test fails.
For example, my mode is stuck on defogger.
@@kroanosm617 I have a video on that, check my most recent two posts,
I added links during the video and at the end of the video, sorry about that, it's hard to keep up.
I don’t get any cold air on mine :(
My AC button didn’t turn on in the first step and the recert light flashed what does that mean
In the description there’s a list of codes that reference the flashes
Thanks so much for this informative video! I had watched other videos suggesting the A/C clutch relay might be the problem (it was), but I didn't have any way of testing the theory out without ordering the part first. I'm just not knowledgeable enough about cars to randomly try swapping things out and around without worrying I'm going to cause some sort of catastrophic failure, so I rely on people like you to give me the confidence to try this stuff out without worrying that I'm doing something wrong. It was your suggestion to swap the rad fan relay with the A/C relay that helped me pin it down as the definite cause for my A/C issue. So thanks again, I appreciate the work you do!
Thanks for the kind comment, I do appreciate your support
My light is flashing on the control head what do I need to do to fix that. ? Just change the control unit?
What code is it flashing?
not sure if you experience this situation I am currently having on my civic aircon.After driving a while longer with AC on turned at the lowest temperature, the ac starts blowing hot air, it literally just heats up instead of just not blowing cold air.
with AC on putting it to low temperature cant defog, now I can only use high temperature to defog.
It does has compressor clutch engaging all but blow wrong temperature. what component do you think it could go wrong? The ac blows normal cold air varies from different temperature I set, most of the time while the car has been driven like the first 15-20mins after a certain time, that symptom starts.
May i ask y a question with a ac issue. I have a honda 2008 mk8 1.8. I filled the ac up with coulant. I replacement the relay
I can hear the ac pomp working. I checked the same wire. I have 1 connection instead of 3, it works. The H intake feels cold but the L intake feels warm. Still the air isnt cool inside the car. What could be the problemen?
🪛🫴 Dumb Ways to Die !
Hey so I have a 2010 Lx, mine blows very cold for about 10 minutes then becomes hot, I ran the diagnostic and it blinked 4 times as I’ve also been having trouble with the buttons, could that be the reason my ac is blowing warm also or do I have other issues?
Will this work for the 8th gen 1.8 hattchback here in europe
I’m not sure , try it and report back if you could
What if it will get cold but then after 20mins it’ll get hot then wait and the cycle repeats
is the evaporator freezing up due to a blockage in the system? try Not using the recirc button and see if its any better
I’m also having an issue with my Honda civic not having ac. A few of my buttons don’t seem to function especially the defrost and no cold air? Anyone have any tips or guesses?
So i checked one of my fans and the one on the left isn’t spinning. Which issue would this be
if your fan isn't spinning remove the connector at the fan and see if you have 12 volts and Ground at the connector, if you do, you will most likely need a fan motor. This is just an educated guess, proper diagnostics would prove this, good luck update me on what you find
My issue is the worst one…compressor clutch will not engage even with giving it the love tap that Danny did. A/c relay sway with radiator swap also did not engage the clutch…
So if i switch the relays and nothing changes, what would that mean?
I have other videos that explain this in detail on my channel
Thank you for the video I have CRV 2007 the AC is not cooling enough I add some frion but still the same could you please help me thank you
Hi Danny thank you. You are a teacher. I changed the relay because the AC was intermittent in my civic 2008 then the odometer cannot be modified and also the AC continue intermittent. Advice please
Wow, I was able to fix my issue, and learned a lot more along the way. Probably the best video or knowledge share I've seen out there.
Danny when I use the a/c the vent closest to the passenger window blows cold but every other blows hot air. I changed the vent actuator
What does it mean when the circulation light keeps blinking? After doing 1:25 please help.
thanks! I think i'm still gonna go to the rip off garage but at least I understand this stuff better thanks to you. my a/c will get super cold but unfortunately it takes about 1/2 an hour for it to happen and most of my driving is 20 min or even less - doesnt' ssound like long but like you said 90's gets hot quick
what does it mean when my car has AC on start up but only lasts like 15-20 minutes on hot days? low freon?
Usually yes, could also be fans, relay, I’m going to do a few more videos on fans and air conditioning since I get a lot of questions
My clutch is engaging, but AC not cooling like before. Can it be a relay issue or need more r134?
My pressure system is messed up and the low side has high pressure and the high side has low pressure. What do I do? Jot trying to go to mechanic
i jus learned that half these mf repairs ill never be able to do by myself
I cannot comprehend your statement, please explain.
What happens if my resert button is flashing ?
Check the description, it has your answer
What if the ac light doesn’t come on with the code?
Not all cars read these codes
I once hit the ac compressor with a hammer gave it a nice good hit and worked a charmed
THANK YOU,
Mr. Danny n God bless 🙌
great.
Absolutely magnificent.
I found one of fans disconnected but that didnt solve it.
Only cold air only coming from one side
So mine blinks 4 times. " 4 times open or short in the in the mode control motor circuit" What does this mean & how can I fix it?
I have that same problem, I should have a complete diagnose and repair video by next week
@@dannysdiygarage You're to kind! Thank you Danny! I've also watched a bunch of your other videos last night & must say I am so happy I found your channel!
Thank you sir you're amazing for this video
Amazing video AC working perfect now thank you.
You're welcome, appreciate your comment.
What is ac r134a psi recharge amount?
Should be on a sticker under side of your hood
