1998 Chevy Truck V8 Four Wheel Drive Automatic 110000 miles
I've been chasing this problem for about a week now. So far I've checked: all fuses, interior wires, replaced light relay in the interior fuse block, replaced the light switch (commonly go bad?), And checked all the bulbs. I also went to the dealer and had them print out the light wiring diagrams so that I could start tracing the wires. I'm starting to suspect that it may be the DRL module, but I've never dealt with that before and would welcome any help in that area. I also did not think that it would be the high beam relay as both the low and highs are out and that is only a 4-pin. All interior lights, parking lights, and signals work perfectly as well.
