A/C COMPRESSOR WILL NOT COME ON!!!!


Recommended Posts

morty96 -- you can't tell what's wrong, exactly, from what you say.  If we have the codes, they may be able to tell us what is up.  The compressor may be turned off because  a code has been set that says that the expansion valve or dryer is clogged, for example.  If you have a gauge on it and it is reading 100 psi, it probably doesn't have a leak.  BodybyFisher is right, a can of the correct Freon every year or two may be OK but that's not going to address whatever is stopping your compressor from running.  Possibilities include, but are not limited to:

  • Electrical problem, like bad compressor clutch ground,
  • Bad compressor clutch,
  • Clogged expansion valve, drier, condenser, evaporator, etc.
  • Etc.

If we have all the OBD codes we may be able to eliminate a lot of things or even focus in on something specific.  As BodybyFisher says, get the codes (OnStar, Autozone, whoever), write them all down, and post them all here.
