My problem is the overhead lights in the cockpit aren't going on. The lower dash lights up with that switch but no upper switch lights or panel lights. The dimmer that controls that is CC installed and they located it down by the park brake button. It is a standard late 80's GM parking light head light dimmer switch.
I have got the switch where I can test it and it works so I am thinking there is a relay in there somewhere because of the large # of lights that go on up in all those panels above the windshield?
In the electrical bay the whole back wall is an shallow electrical box and all the way across the bottom are those little square black 5 pin relays.
I suppose it is here. I guess I could go down the line and check them all before and after turning those lights on.
Am I on the right track here?
This is a 91 XL CC
