My AC has stopped working over the winter. I thought the Freon might be low and started to add some. The compressor is not turning and the freon pressure is at the high end of the scale.
The auxiliary fan does not come on when I turn on the AC. The voltage on pin 7, the wire to the A/C Comp Ctrl unit drops to near zero when I turn the AC on. When I monitor the voltage to the compressor clutch, the voltage with momentarily come up to 12 VDC after I cycle the engine off and on again.
It appears to me that I have a problem with the compressor control and likely a inhibit function. I'd like to monitor the compressor Control terminals, but I can't locate the controller.
1. Can anyone give me a clue as to what to do next?
2. Can anyone tell me where to locate the AC compressor control.
