Well today I decided to go ahead & replace the car stereo in my 2007 Coupe & fix the HVAC Control Module while I had the upper console apart. Disassembly of everything went easy enough although the only stumbling block I encountered was the removal of the HVAC Control Module itself. Illustration in the 2007 Shop Manual as to where to push in the side latches does not clearly indicate where the side latches are. The arrow points to 2 of the latches that hold the HVAC front panel to the rear case. Anyway, problem solved, HVAC Control Module separated, repairs per CL770 completed and HVAC Control Module re-assembled. Decided to stop there since everything was going pretty well up to that point. Tomorrow I'll start re-assembling everything & get my new car stereo installed. Pictures below of effort today.
