Thread: AC Compressor will not turn on

So ive been having this issue for about a week now. Whenever i press the AC button to turn the AC compressor on nothing happens. The light in the ac button comes on fine, i checked the fuse (changed it too) and its not blown. The rad fan also comes on when i press the button, i check the relay under the hood and it looks fine. Anyone knows what could be the problem ?

It could be low freon

If it doesnt come on after refilling it, you may need to jump it useing direct 12v to the fuse under the hood. Your ac clutch may not be engaging. If that doesnt make sense youtube it for visual refrence.

Do you hear a click and see the rpms briefly drop?

got it filled like 2 weeks ago



I dont think theres a physical issue with the compressor. is there a way to get it working normally without "jumping" anything?



no temporary drop in rpm not hearing any clicks either

Do you have a Fluke or test light?

yeah bro i have a test light

Ok, unplug the one wire going to the compressor and see if the test light illuminates when the switch is activated. If it does not, then the problem may be the wiring or relay. If it does then its probably a bad or dirty connection or a bad clutch.

My brother has the same issue currently in his p10, when he jumps the relay though it works and the ac blows fine

Sounds like either the relay is bad, not getting the signal or may need to clean the chassis grounds.
