Working on 08 Acadia, AC button and Recirculation button flashes 3 times and shuts off. Evacuated Freon and changed transducer as High Pressure was climbing to 350 when powering up compressor, ordered condenser to see if this alleviates the problem. Checked again to test circuit and there is no power to the compressor. It has a ground, so will start looking at the schematics today to see what other sensors power the compressor. Any ideas or past fixes?
JA: Is the power loss consistent, or does it fluctuate?
Customer: Consistent on AC Compressor
JA: What year is your Acadia?
Customer: 2008, its not mine, I am a mechanic at AC shop.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Checked Freon lines for leaks, hoses, expansion valve, compressor seals, condenser lines. Freon levels are good and can't find any evidence of leaks.
JA: Anything else you think the mechanic should know?
Customer: I ordered a relay for the compressor to try as I got an trouble code on the relay. Will try it this afternoon and see if the code comes back.
