I am sorry that you have not been helped yet. I just came online and saw your question

Ok, first I need to know if yours has manual or automatic climate controls and second, I need the VIN number in order to pull any needed schematics.

Without looking at the schematics, it sounds like a possible smart junction box control module failure or a short in the wiring harness, but I need to review the schematics once you post the vin number and whether manual or automatic climate controls.

I also need to know what you have in the way of testing - digital volt/ohm meter, full function scan tool, test light, etc, as well as your comfort level in tracing electrical issues and reading wiring diagrams

Ok, I have looked over the schematics and just not seeing a correlation. I am going to open this up to other experts to see what they thing.

Expert:  Randy replied 1 year ago.

One common symptom is for the A/C to stop working, along with an ABS light being on. The problem is usually the ignition switch heating up and not providing power to the A/C clutch and the ABS computer at the same time.
