Can you tell me why the display module lights will not come on? None of the heater or AC functions will work after replacing the radio and HVAC module. Both the fuses for AC have been checked (fuse boxes under dash and under hood) and are good. Car had a fire in the dash after a lighter was tossed carelessly into the storage compartment. 2007 V6, manual transmission, no navigation.

 

Probably no power running to the HVAC display and other related HVAC components due to damaged wiring.
