Chevy S10 - GMC S15 and Sonoma Lighting Issues
I have an all original 91 with only 45,000 miles on it. Now when I turn on the head lights the lights come on but the instrument panel lights go out and the interior dome light comes one. I replaced both the head light switch and the panel dimmer switch but no luck. I took the dash out hoping there was something wrong with the printed circuit on the back but could not find anything wrong. Fuses all seem ok and I could see no visable damage to any of the wiring. Any ideas ? I'd hate to have to trace all the wiring.
