Hey guys, newbie here so forgive me if this topic has been discussed to death. I have a '96 Z71 ext cab that is having headlight problems. I have replaced all four headlight bulbs, low and high beam. When the headlight switch is in the off or parking light position the DRL's work. However, if the switch is turned to the on position, I have no headlights. I installed a "new" switch from the local salvage yard, but no change. Any ideas?
