No power to A/C clutch ?

[pitbulldell]

There is no power to my a/c clutch. I even took a paper clip and jumped the pressure switch and still nothing. I used a test light and there is no power to the switch .can someone tell me where the relays and or fuses are located to try and fix this problem . No a/c in this heat is not good. thanks

The AC circuit to power the compressor has several switches in it. You can find wiring diagrams at the following website:

Wiring will be slightly different for the manual versus the EATC system. Good luck.

If you run the spectrum of standard tests and still can't find the problem. Pull your EATC unit open it up and check for bad solder on the PCB. Pay special attention to the Omron relay internal to the EATC.

+1 if you have the EATC HVAC controls. The circuit board can get cracks in it's solder joints. I've read about this being the problem in at least 4 reports of A/C compressor not running problems. As far as relays, check your owner's manual for locations (most are located in the power distribution box in front of the master cylinder). Also check fuses if you haven't done that already.

I you don't have an owner's manual, I think the inside cover of the power distribution box may help identify which relays/fuses are for what.
