The cabin air temperature sensor is on the driver side, right? Where is the ac amplifier located? Did you have to completely disassemble the center console (like you were changing the stereo head unit)?
I have an 06 with misbehaving air conditioning. If swapping the bottom air-mix servo doesn't fix the problem, maybe I'll take a look at the ac amplifier...
