instrument panel lighting
Question:
A cry for help! The instrument panel in my ‘99 C2500 Suburban has just recently gone on the fritz. The light for the instrument panel does not seem to come on when I turn on the lights. I checked the fuse and replaced it (even though it did not appear to be blown) The interior dome lights still come on, as do the instrument lights on the AC and radio panels, but for night time driving I can’t see my gauges worth a flip. The buzzer that usually sounds when you leave your lights on after you’ve cut the ignition is not working either. I don’t think my taillights are working, although the brake lights are still functioning. This is the first time I’ve run across this problem in the numerous Chevy and GMC trucks and suvs that I’ve owned or operated. Any ideas or advice would be appreciated.
Response:
Start with the taillights. The running lights are grounded to the body [ rear bumper ] follow wires until you find ground. Remove ground, clean and reinstall [ A stainless screw is recommended, as is painting over clean, tight, ground ] A mickey mouse body ground would cause the stop lights [ which have a seperate ground ] to work, and the running lights not to. Could also be faulty light switch.
