Hey guys I just replaced my ac-compressor with a brand new AC-Delco Compressor and the computer shuts off the compressor after it has been running for about 2-3 min. If you unplug the battery and reset the computer it will turn on again but only for 2-3 min. Anyone have any idea why?

 

The computer monitors A/C pressure; if your pressure in the lines is too low it will shut off.

 

Meaning I have a leak right? What are some good places to look for a A/C leak?

 

My problem started with my A/C not working, no cold air. I also had a DTC for the A/C clutch not engaging, I figured it was the A/C clutch, changed the compressor and its the same problem.

 

My friend's 95 has a slow leak through the AC schrader valve. I'm sure a shop could pressure test the system and find the leak.

 

Maybe you overcharged the system!

Did you add Ester Oil into the new compressor before installing it?

 

Do you mean PAG oil?
