Results! While I am proficient with a soldering iron, I do not have the workspace of my dad's garage, so I ordered the re-man CCRM. Part came in this morning, but before installing I did a continuity check the BLK/Y wire from the old CCRM to the A/C clutch to make sure that there wasn't a...

Crossed signals I believe we are getting our messages mixed up and I take responsibility as the posts from my phone are not as well-organized as the posts from my computer and, for that, I apoligize. To get back on track I will consolidate your requests and the results of my tests in this post...

which ground test?

Sorry if you check my posts I got 12v out of bOth sides of the high pressure switch. I was careless last night but have checked at least 5 times today and there is power on both sides of the high pressure switch

Just had an ODB2 scan at the local auto parts store and got no codes. May be inconclusive, however, as I had disconnected the battery a week ago to turn off the check engine light so I could pass state inspection. The check engine light had previously given a code for low gas cap pressure, so...

Measure the resistance from CCRM pin#15 (BK/WH) back to battery negative with the key off. Post. Should be low. If not, check for bad grounds at the CCRM and battery. --1.9 ohms Test CCRM pin #21 (DG/OG) for +12 volts. If no power, you failed because AC pressure fuse is bad. --confirmed 12V...

Since you stated measuring less than one volt on the high pressure DG/OG wire, THIS is why the AC isn't engaging. --was tired last night and must have had a bad connection...measured 12v Test for +12 volts at the high pressure switch DB/YE, If power into the high pressure switch but no...

Troubleshooting begun... Confirm the A/C pressure (20a) in the battery junction box. --Confirmed (Just measured the voltage (12), If I understand correctly, this is easier and faster to test voltage from each lead on top than pulling and measuring resistance, if not, let me know) Also...

I have recently been having issues where the a/c clutch will not engage, so I am getting hot air blown into the cabin. I have tested a number of things, but at this point i am having trouble stiching together the information on various forums to find a way to continue, so here is the run-down...
