2008 Compass AC issue
The AC stopped blowing cold air in my daughter's 2008 Compass... oh, we live in North Texas!! I noticed the clutch is not engaging. I had a buddy with gauges determine there is plenty of Freon. The service guy at the dealership said the control unit (below radio) in Compass' often go bad. I put in an oem controller and still no cold air. I can't find a low pressure switch anywhere to check/bypass?? Last night I checked the voltage at the compressor and got 3.7v. I'm guessing it should be 12v so it appears to be an electrical issue. Any suggestions on next steps/options to make the air cold?
