I thought I would follow up on my progress. I received a second control panel yesterday and plugged it in hoping it would solve the problem, and it had the same issue. Lights and buttons for 4x4, hazard lights, clock, passenger seatbelt all work. However, A/C control did not. After checking some more fuses I was going to replace the control panel with the previous one. The car was running while I was doing this, and when I disconnected one of the connectors on the back of the panel the A/C control light came on and I was able to control the HVAC. Not only that, the temperature gauge began to work. Seems to confirm it's a wiring, perhaps grounding issue. Still have not traced it. Also, rear A/C control is not working still.
