Still hoping for some help here. Last suggestion of changing to C wasn't useful - the test results don't change based on whether you're reporting in C or F.

One thing I noticed is that I've got complete fan control when the car is in heating mode. Go to A/C and the no fan control problem starts.

Any suggestions? I'd hate to have to take this to the shop when it's likely something we can diagnose and I can fix myself.

Thanks!
