I have a 86 grand prix 3.8 v6.
My problem is I have no headlight or tail lights but the brake lights and turn signals are fine. When i try to turn headlights on the check engine light comes on and the dash clock stops working??????
I have already tried replacing the headlight switch so that is not the issue.
Any ideas guys??? this is my daily driver so it kinda makes it hard to get to work at 3am with no lights......
