I discovered over the weekend that my 3rd brake light wasn't working. I looked around inside the engine compartment and discovered that the wire leading to the brake light was cut in two. I wired the wires back together, but the lights still were not illuminating.
Using my test light, I have determined that each bulb socket is getting juice, but the lights aren't illuminating.
I'm not an electrical genius, but shouldn't there be a ground wire leading back into the engine compartment? I don't see anywhere in the bulb socket wiring that a wire connection is missing.
