My a/c was not blowing cold air. I put gauges on the high and low and both showed good pressures so not lack of coolant. Right after checking the blower motor stopped working. I pulled a/c fuse in driver well. It was good but seemed to go back in super easy with little friction.


Also noticed ambient air temp shows -40 all the time when it is 70 out. Seat heaters don't seem to be working either.


Any ideas on where to start?

 

Have you read about battery voltage related problems yet?

Sounds like you have several semi related problems.

Blower resister modules are available on eBay for cheap.

 

I finally got around to test the blower modual beside the blower motor. That was the blower issue and works now with the replacement. Thanks for the advice. Still no cold but that will be next. Likely freon issue.
