I have an issue with my heater/AC controls. Everything works except the center control. The fan works fine, I have put it in to the 0-16 temp mode and it steps through them all fine.
When I press any of these buttons, it beeps, but nothing happens.
All fuses are tested and good.
I resoldered the temp **** anyway.
When I turn on the car lights, the control panel backlights come on correctly.
If it beeps, presumably that means it is all connected ok?
What else can I try?
