Okay thanks. Well you done right checking fuses. The first step will be to remove the bezel and unbolt the control head, pull it out and we are going to check the voltage and ground available
Sir are you still working on the car? I apologize for the delay. I had a situation i could not avoid
The Climate Control Panel (CCP) is inoperative. Has auto Heat Vent Air Conditioning (HVAC) system. The panel is completely dark. The radio lights up OK. The power/ground to the CCP is OK.
Average Reported Mileage:180000
Tests/Procedures:1. Check the B+ feed to the CCP, Orange wire, pin C12.2. Check the ignition feed to the CCP, Brown wire, pin C5.3. Check the ground to the CCP, Black/White wire, pin C1.4. Wiggle the CCP connectors with the key on, watch the panel for response.5. If no change, replace the CCP.
Its been a while since I worked on one of these I dug this up in the repair database. There is not much you can do other than check those inputs. Those units and the digital dashes were pretty much self reliant so other than powers and grounds that was it. Let me know what you find after checking this
