Thanks for this. AC started up real quick after removing the relay and putting it back in. Saved me $34 on a can of Freon that I didn't need.

recently swapped my battery, ac was stuck on blowing cold air, but the controls weren't working to switch it off or anything. swapped the 2 relays like you said, worked! saved me from a massive headache man. Thank You!

I paid Firestone to repair my AC almost a year ago, 2800 bucks later and my air is still hit or miss. All seemed well recently and now the air is out, clutch not engaging. I knew I should've done it all myself and saved a grand. Gonna check my relay when I get home. Thank you for the location. Those maps under the lid always twist me up.

Does the clutch relay feed power directly to the fan clutch without going through any cut-off switches ?

So, what if the fuses and relay are good. As well as the clutch and Has great pressure. And its still not working? Would that be the cycle switch on the accumulator? Or the compressor itself?

If there is power getting to the compressor clutch and it is not engaging then I would suspect that the ac clutch is bad. I'd recommend changing the compressor assembly

Check to see if the compressor is receiving power. If it is receiving power but not engaging then replace it. If it is not receiving power but the fuse and relay are good then you may have an issue with one of the pressure switches or maybe the hvac panel itself

My AC isnt working (already tried the fuse/relay) but it turns out the little indicator lights on the AC, rear defrost and air circulation buttons all aren't coming on when I press them do you know what could cuase this? Most likely a coincidence but my battery went bad and everything was working fine and when I put the new one in it was like this
