3100 V6
tech = JK
question = WELL I JUST GOT MY 95 CHEVY LUMINA TWO WEEKS AGO AND THEY
SAID THE AC WORKED WHEN MY DAD BOUGHT IT AND 2 DAYS LATER WHEN I GOT TO
DRIVE IT FOR THE FIRST TIME NO AC I JUST HAD MY BROTHER PUT FREON IN IT
AND IT IS ALREADY FULL BUT THE COMPRESSED WILL NOT TURN ON AND HE
CHECKED THE FUSES WHAT ELSE CAN IT BE.

JK:
There are several things that control the compressor. Compressor relay, high and low pressure
switches, the pcm, the control head in the dash, and all the related wiring between all these
components. The first step is to check for each switch for proper operation, check the relay, and
check that the pcm is grounding the relay.
