Issue: Fan motor not responding to position switch setting
Repeat?: First issue of any kind with HVAC
Model: Tech with Auto
Mileage: about 7800

Yesterday I got in the car, started it up, and the fan motor didn't seem to be on(A/C mode Max and Recirc). I moved the speed dial around, and it only worked on 3. I turned the car off and then back on. The fan motor worked, but not with the dial on position 4. When turned to 4, the HVAC system would shut off like in position 0. Jiggling the dial a little in pos 4 did nothing. If I turned the dial back towards 3, the whole system would kick back at 4th speed. I also found that if I pushed down on the dial in position 2(straight up), the fan speed would drop to about the speed of the 1. Let up on the dial, and the fan would speed back up. I only noticed this because I was wiggling the dial at various speeds to see if it seemed to be a loose connection electrical problem.
I'll see what the dealer has to say. I would assume that a replacement switch/module is in order.
