When I recently tried to use my air conditioning the other day, I noticed that only hot air was coming out. I let it run for about 10 minutes and it never got cold. So I figured maybe I needed a re-charge. When I was going to test the refrigerant pressure, I noticed that the A/C compressor clutch was not spinning. So I tested the refrigerant pressure and it was way too high. So I let it out while the car was running until it was at the desirable PSI. The clutch would still not engage. So my father and I tested the voltage on the two plugs going to the compressor and all the fuses. The fuses were fine, and the pressure switch had the correct voltage; however the other plug going to the compressor had no voltage going to it. What could be the problem? I'm out of ideas :headscratch:

I had the same problem when I first charged my air, what I did was I connected the pump directly to the battery so it had an ass ton of juice. Since than my a/c clutch engages every time. :bigthumbsup

What pump did you connect to the battery? And it's looking like my problem is the main plug going into the compressor doesn't have any power. It's located directly underneath the clutch...

Install a jumper connecting the wires going to the pressure switch, if the clutch engages then your pressure switch may be bad. About $25 for the part.
