I have a 2002 Monte Carlo SS with 230k miles on it. The motor and drive train run greats and I really love thi s car.

I am having electrical issues. I ch angled the BCM because my cruise was not working as well as other indicators not working properly. After reading thi s forum I changed the BCM due to many similar issues and the resolution to change the BCM.

The problem I am having is the air/heater controls do not work and the panel does not light. The overhead switch s for the sunroof does not light, the cruise does not work even though the cruise light comes on. So it seems that I have a problem with some electrical module of sorts.

Any suggestions to fix?
