Nice video and explanation. I had the same issue when I came across your video. The AC button was not showing "on" on the tester. However, I started the self-diagnosis on the head unit, and it fixed the problem. It might be worth a try before you change the head unit. So, if somebody has this problem, try turning the ignition to position II, holding the off button, and then pressing the defroster button five times.

Thank man man now I know what’s the problem Mechanics can’t fool me anymore 😂

[@albertoreal3734]

I just fix my AC thanks to you bro.

[@autopurlieu]

I’m glad you got it fixed 👌

[@brextonbennett3642]

Excellent video. Thanks for making this

[@autopurlieu]

Thank you. I hope it helps you

[@PROofHAPPYWHEELS]

Thanks for this video bro and the explanation I really appreciate it

[@OscarHernandez-rj1dl]

Nice job bro and would have done the same thing. Great video

Awesome video , thank you so much. Quick question. My accord 2004 ac doesn't work, the compressor clicks and engages the clutch when I supply it with power but when I run the car it doesn't work

[@autopurlieu]

Try to follow this video and see maybe one of them aren’t suppose to be doing right . What do you mean it doesn’t work? It doesn’t click ?

[@renatohoxha561]

Hi, I just have a quick question please if you change the high-pressure switch do you need to drain all the freon out of the system or will it shut off itself thanks.

[@autopurlieu]

Depends on the system. In this accord, you have to recover all the Freon first before removing the high pressure switch.

[@chicoloco44]

quick question. my AC air comes out and i can control the temp of it just fine. the issue is that the air will literally not stop coming out unless the car is off. even if my ac switch is set to off. any ideas? thanks!

[@autopurlieu]

I have a separate from about that. Come check it out kzbin.info/www/bejne/Y5zQlINsncmag7M

[@ROLALOS]

Mine goes on n off literally every 5 seconds, butbif i run the car on the rd than it goes on n stays on. Any advice?

[@KWIKWS6]

Have a 09 accord and the AC stops working if I use max AC. Otherwise it works fine. But once you use max AC, the normal function will also no longer work until the car it turned off for a while

[@autopurlieu]

Are you sure it’s the ac stops working or just the blower motor ?

[@Don-ig4xp]

What if Both My fans don’t Turn on like that often? My fans only turn on once in a Blue Moon and only be on for like 5sec then cut Back off

[@autopurlieu]

Does your heat works ?

[@josuecarranza8124]

how much does it cost normally to change the compressor?

[@autopurlieu]

Depends on the shop per labor hours . It could go from $500-$1200

[@brokenalgorithm]

I think my compressor is working and there was ac in my line when I checked with screw driver in low side, but still blowing hot air

[@autopurlieu]

You need a pressure gauge to check the pressure .

Hey my friend, what is the next step if the compressor dont receive signal to start?

[@autopurlieu]

You have to check why there’s no signal. There’s plenty of factors for that

[@jorgehetnandez1696]

Did you ever find the problem? My AC compressor is not receiving power but the fuses and relay work.

[@josemarrero7982]

@@jorgehetnandez1696then it’s obvious your ac compressor is no good

[@marioatrucking]

Yeah. My fuses and relays are good. But my Compressor is not getting the power to turn on. I'm so lost and confused 🤔

[@jasspreet311]

What if ac compressor working but not blowing cold air

[@autopurlieu]

Maybe you have low Freon or pressure.

[@timvu3095]

This is a horrible video on how to troubleshoot and fix an AC failure, regardless of vehicle make or model. Assuming the AC system does not lose freon, the majority of the AC compressor not running is two things: the AC compressor relay and the AC clutch fuse/relay. If either one of these are bad, the AC compressor will not run, and they are the easiest to find, they are in the fuse box under the hood. The AC compressor and AC clutch fuse can be easily tested to determine if power are sent to the AC compressor or clutch. If the power are sent to the AC compressor and it still does not run, it is likely a bad compressor and it can also easily checked if it is seized. There is no point of checking for the pressure switch or the power terminal at the compressor if it is already dead. The proper order for diagnosing AC system is really, AC compressor relay, AC clutch fuse, the freon level, the compressor itself, and the pressure switch.

[@autopurlieu]

But in reality , you don’t assume things or that the ac system does have Freon. You must check every possible cause. Hey you do you sir. Thank you for advice
