Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Before condemning the Compressor (which is a definite possibility here) I would recommend that you have the Diagnostic Trouble Codes retrieved from the on-board computer. "SOME" local parts stores, like AutoZone, can read these trouble codes and will do so for Free (except in California). These trouble codes will point towards the faulty part/sensor and from there, a more accurate and efficient diagnosis can be done with testing procedures to ensure the correct item is replaced to solve the problem. If you cannot find a local part store with the correct scan-tool to retrieve the codes, then unfortunately, a shop will be needed. If the problem does come down to a Compressor issue, this sells for around $526 and the Labor Time Guide calls for just under an hour to complete the job.
