Hello! I just recently purchased a 1992 Chevy Suburban 1500 2WD, and most of the exterior lights do not come on. That includes the headlights, tail lights, brake lights, and turn signals. The park lights do come on in the front, as well as all dash lights working/dimming. I have checked all the fuses, and will be replacing the turn signal switch, as well as the light switch. I have not checked to see if there's power to the bulbs yet. Is there a wire or ground that connects the brake lights to the headlights, that would cause them both to go out? Or is it just two separate issues that are happening at the same time? I can see there's some sign of mice, but not much, so my guess is a chewed wire or wires.
