no electronic signal going to the a/c compressor. hot air only, no a/c


Asked by Jun 09, 2017 at 12:35 AM about the 2002 Saturn L-Series 4 Dr LW300 Wagon

Question type: Maintenance & Repair

where can the code be found to reset the BCM (body control module) ?
where can I find the exact part number for the BCM so my mechanic can
reset it ? This is my second BCM installed & I do not know if it was reset with
a code.  Maybe that is why I have no cold  a/c ?

1 Answer


there's a pressure switch that will cut compressor power if there's no freon , probably a relay too .
