- This is a video tutorial of how to diagnose and repair your car A/C. Wether your car air conditioning is not blowing or blowing intermittently this video will help you get to the bottom of your issue then show you how to repair said issue. This video shows you how to test your transistor, relay, and how to perform a diode test to figure out if your blower motor is good or bad. These diagnostics were performed on a 2003-2007 Honda Accord 4 cylinder but will work on the 6 cylinder engine as well.

THANK YOU for, not only, showing how to check what the problem is, but also, recording yourself doing it so I’m not second guessing what goes where.
Hey thanks for watching. Happy to hear my video helped. I couldn’t find a clear video myself so I filmed one. Hope you subscribe!
Love that your lil helper is nearby. Thanks for the Vid.
Hey thanks for watching! Yea he’s a good helper couldn’t do it without him lol. Hope you subscribe!
Thank you so much!!
@denisejohnson7942 Hey thanks for watching. Happy to hear my video helped you fix your issue. Would you help me fix my subscribe button by tapping it I’d greatly appreciate it!
My A/C stopped workin a long time ago and technicians learned that it is not a leaK and not the compressor. If this video helps me I'm definitely tipping a thanks to you. Might need to learn how to replace a transistor though
Hey thanks for watching. I hope you find the issue. I also have a video on how to replace the transistor.
Thanks for the upload to show how you had fix your problem. But it seems strange to me that the relay ("snow" symbol) you had swap out was for the AC Compressor. I would have thought since the blower was not blowing, it may had been the Blower relay (the "fan" symbol) that is above it.
Hey thanks for watching and taking the time to comment. Yea it’s tricky diagnosing these issues without a multimeter. Most people assume the blower relay is the issue when your fan motor isn’t blowing but by using a multimeter you can test it to make sure and not just throwing money away replacing part after part. That’s why I made the video to help people. Hope you subscribe!
I tried doing this with my 2006 Ford Taurus but apparently because of my weight lifter I'm too damn big to fit underneath so I can't reach it😂
Hey thanks for watching. Dang that’s a very common issue 😂 I had to push the seat all the way back to even get a piece of my body in. If I had to I’d probably get my wife to do it 😁 hope you’ll sub to the channel.
@@ucanfixit1 yeah this is as far as the seat goes back I have to get one of my friends to do it this sucks but who knows it could be just a smaller problem like a fuse
@@juggalogamer8541 no big deal I’m sure someone will give you a hand don’t forget to let me know how it turns out.
I'll prefer to check relay before checking the transistor. Easier ones first.
First off, thank you for the time and effort to make this video. However I did all these test and my issue remains. I think it is in the A/C controller unit where the buttons are at. The issue I’m having is when I first start the car and I turn the ac on, everything works it even blows cold air but 20 seconds later everything shuts off. No air, the fans stop and the compresor disengages. Then I run off ac and on again and nothing. If you have any idea what that might be please advise. I already checked the diode and ohms and the fuse
Hey thanks for watching! Definitely sounds like a short somewhere. I’d change out the controls and if that doesn’t work I’d trace each line and wire making sure there isn’t any nicks or cuts. If you do this and find nothing take it to a mechanic to find the issue for you and fix it yourself. Hope this helps.
Ami me pasa lo mismo
My fan blows when I turn on the A/C but its not cold. Also, there are no freon leaks. It holds the charge. I'll try this and let you know if it works
Hey thanks for watching. I would start with these methods and go from there.
I had thought it was my ac compressor because it wasn’t cold and I didn’t have any Freon. When I bought it and put it in it was in the red. I let it out then put the Freon in and it was still hot.I will check these things before I buy a whole ac compressor but the compressor didn’t click on after putting the Freon in.
Hey thanks for watching! Check the other things in the video and if everything checks out it is most definitely your compressor. Hope this helps don’t forget to subscribe!
I have a 2 door coupe Honda Accord 2003 the air blows when it not that hot outside but heat blows when it is hot outside it’s full of air what my problem I wonder
Hey thanks for watching! Without actually being able to troubleshoot the car it’s hard to say but it sounds like you might just need to recharge it with some freon. Hope this helps! Don’t forget to subscribe!
I got a 2005 Honda accord I’m not getting any air out the vents at all or anywhere for that matter I’ve changed the resistor and I’ve changed the blower motor all fuses and relays are good what’s else could I be missing ?
Hey thanks for watching. Next step I would take is to make sure you are getting power and verify you don’t have a short somewhere.
@@ucanfixit1 okay will do
My ac/heat doesnt blow trued switching out relays idk if its tr blower motor or compressor
@allisinjackson4559 Hey thanks for watching. I made a video on how to test the blower motor go check it out. If everything checks out it’s probably the compressor. When you turn on the ac the compressor should kick on.
What if the buttons doent work after I check all fuse good put new relays still nothing checked the thermistor good what else can I check?
Hey thanks for watching! It’s possible you have a wiring issue if everything checks out and your only issue is the buttons. I’d check my wiring and then the actual mode control panel the buttons are on. Hope this helps.
@@ucanfixit1 car says engine must be on before climate control how doni check the wiring is their a diagram you can post?
@@mmar4281990 I was able to find this on google.

Another way to test if is bad ,just conect a piece of wire into the conector if the blower runs ,you know that is bad
Ever think about using phone stand?
Yea but I feel like I can move better and easier when it’s in my hand cause I’m working at the same time I’m filming. I’ll look into it and maybe give it a try.
Mine is having the same issue but it turns on when I hit the blower motor do you think it’s just a bad blower motor?
Hey thanks for watching! It could be the blower motor or the transistor. I’d test the transistor and if that turns out good then most likely it’s your blower motor. Hope you subscribe!
Just take out the blower motor and use compressed air to clean it. Reinstall it, and it may fix the issue. Leaves and debris often accumulate in there
@@Chriscovelli1 the blower motor in the 07 Honda Accord is underneath the glove compartment so leaves getting in is rare.
@@ucanfixit1 I gotcha. Yeah, if it's not easy to reach, then might not be worth the time. Keep up the good videos my friend!
@@Chriscovelli1 thank you I really appreciate it I definitely will and I hope you subscribe!
Mine turns one whenever it feels like it and sometimes it doesnt turn on at all unless i start driving like at 45mph its annoying because its 110 plus degrees
@@danndan4470 hey thanks for watching. A number of different reasons could be the cause from a bad compressor overheating turning on and off, the thermostat, clogs, and even a dirty filter. Unfortunately without being able to physically troubleshoot the car myself it’s hard to say.
@@ucanfixit1 Most of the time the ac works fine but like right now and in some other cases it doesnt turn on, well it does turn on but no air comes out
@@ucanfixit1 because i can hear it turning on and running but no air comes out ive already changed the air filter i really hope its not the compressor that would suuuck
@@danndan4470 did you check the blower motor? It could also be going bad.
@@ucanfixit1 I think thats what it might be I looked up another video they had the same exact issue as me they switched out a part near the blower i might have to do that
I switched out all the relays, fuses, and the transistor. Still not working. I looked at my A/C compressor and it's still running, but still not blowing cold air
Did you check to see if you have Freon?
@@ucanfixit1 the freon is full.
@@gabrielsaravia5388 is the compressor clutch engaging and spinning when the AC is on?
@@ucanfixit1 yes
@@gabrielsaravia5388 Could be your condenser or evaporator but best thing to do now since you did almost everything you could do is to take it to get checked out and see what they find once they tell you then just go ahead buy the part and fix it.
