okay well after bench testing my old compressor i found out it was fine. we found out the problem is the plug going into the compressor. I don't know if its just a bad plug or what.

Where does that plug go to. I saw it plugs into the compressor and then gets hidden behind the wiring harness. I'm going to go to the dealership today to get the plug/wires but i don't know where it goes on the other end.

On an LS1, the compressor is controlled by the computer (PCM). It will run continuosly when switched on ulness you are at close to full throtle or in the R134A line pressure sensor is reading low.

my problem is the compressor isn't getting the signal to pop out and start spinning. when i jumped it right from the battery it worked perfect and blew cold air. I tried jumping the switch and no go. the fans turned on but the compressor didn't spin. so is it possible the connector is bad? and if it is i will pick up a new connector and where does the other side of that connector go to? the pcm?
