1988 GMC C1500.
Okay, so I just noticed when my DRLs are switched on, my brake lights don’t work. Everything else works as designed. With the DRLs OFF, the brake lights work. When I have a turn signal on, the brakes work as well. Hazards work. Signals work. Literally everything except when DRLs are on the brakes don’t. Please help!
