Did you check the rear hatch switch and that the dimmer knob isn't turned all the way up?

If could be a defective headlight switch itself. I had to replace mine last year because it was doing strange things.

The GM manual will have the diagnostic procedures for the interior lights. The manuals can be downloaded here, go to post #77 for the 1999 links:

88-98 Service Manuals

I looked at every post, there's lots of excellent info in this thread! any chance there is a link for a 1991 GMC Suburban V1500 manual that can be shared? On the forum, search the engine thread " service manuals " look at all the manuals, find your year, 91. It will cover all the models based...

Push in the "Overide" button by the headlight switch, instead of pulling the fuse. I have run my truck for years like this. I will check my barn doors now that I am thinking on it. I have replaced both contacts at front doors.
