[QUOTE="hal keiner, post: 1016042, member: 66101"] I fixed my problem with the AC. For those that come across this thread trying to solve a similar AC problem, I thought I would explain how I found and solved it: I checked for voltage at the AC compressor connector with the AC turned on at the dash and there was no voltage. I then checked for voltage at the female ports/pin outs inside the Battery Junction Box where the AC clutch relay is plugged in. I found that there was voltage at the appropriate ports/pin outs and so I suspected that perhaps the AC clutch relay is bad. I didn't know how to readily test a relay but as it happens, the horn relay located in the same Battery Junction box is exactly the same part. I switched them out and found that the horn stopped working and the AC compressor started working. For the cost of a new relay (about $13 at my local auto parts store) I got my AC working again. Yeh!
