QUESTION: No. We checked all that, my husband even took the whole thing apart, the bulbs are good as well. The interior lights work, everything else works except the instrument panel lights and the lights around the radio. No after market radio.
Answerok this is gonna be a hard one to swallow the body computer is what controls the lights U are talking about there brightness. U have either a BCM or a junction block issue being that they are hooked right to each other there us no way to test them unless u are an electrical engineer and have the blue prints to this system.
U can replace one then the other or both at same time.
