Problem was the ircm integrated relay control module. Thanks KMT!
Ok, so I've decided to refresh all the o-ring seals on my a/c system and charge it up before it starts getting hot. And to allow the defrost function to work properly for now while its cold.
I've already replaced the o-rings with HNBR O-rings on the back of the a/c compressor x2, the two lines at the condenser 2 on each, those same two lines at the other end(close to firewall) 2 on each, now it appears all I have left is the line at the accumulator by the firewall? Am I missing any that are under the hood?
I will also replace the pressure switch while I'm at it.
Do these a/c compressors typically last a log time, or would it be reasonable to suspect this one may be bad? Every O-Ring I removed was very dry/cracked, so I would suspect that is the reason the a/c stopped working instead of failure of the compressor. The system would hold vacuum only for a couple seconds when I vacuumed the system down before putting the new o-rings in. Also there wasn't any refrigerant left in the system.
Thanks,
Brandon

I replaced all orings finally. Vacuumed down the system for about 30min. Filled the system. Has about 38psi on the low side. The clutch won't engage, & there is very little power going to the compressor wires on the top. I jumped the clutch with a direct 12v wire & it came on right away. I replaced the pressure switch already. I also tried the old pressure switch, nothing happened. Any ideas what could be wrong?
