So I have a 95 Suzuki Sidekick and the RR brake light doesn't work when my headlights are on and it is dim when my headlights are off. My reverse light doesn't work at all. I replaced the plunger, replaced the bulb, and cleaned any corrosion off. The ground on that socket has a few wires that broke away from the wire and it was doing the same thing before that happened. I'm not really sure what's the problem? Can someone please help me? I have researched A LOT! It would be greatly appreciated.
