Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello & Welcome,
Can you tell us the Year, Make, and Model of your vehicle?
OK - Thanks.
Do ANY light change (turn on or off) when you open and close the doors?
Let's start with the basics. You should have a dimmer wheel, next to the headlight switch, as shown below.
When you turn that wheel from full off (or Low) to full on (HI), does it feel like the wheel is moving smoothly, and do the instrument panel lights change in level?
Hmm - Interesting.
Can I assume you have pressed the "button" on these lights to make sure they were not manually switched on?
Can you tell me which fuse you pulled out (which fuse box it was in and what the label is)?
I'll check my email in the morning. Let me know if you can help me more.
I have to leave the computer for a little while, but I am starting to suspect either the internal part of the dimmer switch, which feeds the ground side of all those lights, or a short to ground in the wiring. Here are the schematics, if that helps.
What I would do is get to the back of that switch and pull off Pin B (the white wire) and see if the lights go off.
