Sorry to ask an off topic question but I was hoping that someone might be able to help me. Just bought my son a 1983 GMC S15 with a 2.8L six and am having some electrical problems. The dash lights are quite dim and when you turn the light switch to brighten them they never get very bright. In fact when you turn the light switch very far all the electircal guages quit working! I did not think that the light switch is supposed to affect the power or working of the guages is it? Is the light switch faulty? Any help would be appreciated.
