It Works! Sorry for taking so long to get back to you. The problem did indeed end up being a bad CCRM. I got it replaced and am once again enjoying Air Conditioning. Thanks for your help!

I won the auction for the CCRM. I purchased a used one for $42 with shipping. It probably won't get her until next Tuesday unfortunately. Let me know if you have any other ideas in the mean time. Thanks!

I just had another thought. When I jumpered the high pressure sensor connection, there was +12V going through the jumper. Wouldn't that indicate that the Heater Control Assembly is working properly as it is allowing power to get to both sensors. Ah! That gives me another thought...I think...

Here's the heating and cooling diagram from my Haynes manual. Is the AC Clutch Cycling Pressure Switch the same thing as the low pressure switch? If so, then I believe I have ruled that out by jumpering it. I have also ruled out the High Pressure Sensor by jumpering it. This really leaves...

The only fuse that seemed relevant under the hood was the one for the CCRM / PCM. It was good. I made an offer for a CCRM on eBay, but would be extremely happy if I could get A/C before the weekend, without spending a ton of money on it.

Sorry, we posted at the same time.... To answer your question, it was 0 volts on the car side of the connection. In regards to the fuses, I pulled out the fuses under the dash and they looked good, but I did not pull out any under the hood. I will see if there is anything I can mess...

Progress Ok, so here's where I'm at: I was able to locate the high pressure sensor and I jumpered/bypassed that as well as the low pressure sensor. The compressor still did not kick on. I went an bought some alligator clips and was finally able to connect the compressor clutch directly to...

Oh yeah... All the fuses looked good as far as I can tell. Also, I put my voltmeter probe into the plug that plugs into the clutch and I was getting 0 volts, so my guess is that there is no power even getting to the clutch. I will continue trying to apply power directly to the clutch and see...

Ground as well Ok, I pulled the electrical connection that goes to the clutch. I ran another wire from the positive terminal on the battery and poked it around inside the connector on the Clutch side, but nothing happened. I'm assuming I also need to make sure their is a ground to the clutch...

My air conditioner quit working the other day. I popped the hood and noticed that the compressor clutch was not engaging. What can I do to diagnose this problem. I jumpered the low pressure sensor switch and the compressor still did not engage.
