i am trying to troubleshoot why my a/c compressor is not engaging on
my '99 chevy k1500. i thought i knew what 2 of the 3 electrical
connections on the compressor did what, but now i have my doubts.
before i go any further with the troubleshooting, i would like to get
some clarification. can somebody tell me the purpose of the 3
one is at the front top of the compressor, near the serpentine belt.
another is connected to the top of the compressor, going back toward
the firewall, near where the freon hoses are connected. the third one
is at the rear of the compressor.
thanks in advance...
