2001 Chevrolet Impala 3.8L


Already Tried:
Turning the car off and restarting; pulling light switch on and off.
Expert:  Dave Nova replied 8 years ago.
The interior dimming lights are controlled by the body control module. The radio lighting and the dash panel lighting are controlled in the same way. If the radio lighting is working as it should, the problem is in the gauge cluster. If the radio lighting acts up at the same time, the problem is the body control module.

OK, but where is the body control module and is it something I can replace myself?
Expert:  Dave Nova replied 8 years ago.

The body control module is located under the drivers side of the dash. It is easy to change, but the new module must be programmed by the dealer.
