Scotty Posted July 8, 2004 Report Share Posted July 8, 2004 Did you check the fuse for the AC COMP? The AC COMP fuse supplies power to energize the relay if I am not mistaken. Mike Link to comment Share on other sites More sharing options...

Ranger Posted July 8, 2004 Report Share Posted July 8, 2004 What about the relay in the fuse compartment? I think there is a fuel pump and an A/C relay there. Swap them and see what happens. Link to comment Share on other sites More sharing options...

KHE Posted July 8, 2004 Report Share Posted July 8, 2004 Did you check for codes in the diagnostics? Maybe there is a leak in the system and enough of the refrigerant leaked down that the system won't allow the compressor clutch to engage.
