Right rear brake lights fail. Entire socket assembly and bulbs have been replaced. Bulbs always have a melted and scorched end. Now the left side does not work although all the bulbs are working...brake lights do not. Only the brake bar at the top rear window works.
Determined it was the black wire causing the short, made a direct connection with a wire I fastened onto the plate and connected it to the lead black input wire bypassing the harness connection. Had the exact same issue on a 99 Montana Driver's side brake light.
brakes light failed, replaced with new bulbs, not working, noticed that wire pins in plate were a little flat and not making good contact, carefully bent wire contacts up a bit, it worked, old bulbs were fine, cost $0.00, tools: small screw driver or paper clip, time to fix: a few minutes

all my lights messed up in back
The rear lights wont. When I signal, on the dashboard, all I see is a dim light on the direction im going to. Basically, the signals dont work and Im looking for a solution
Brake lights burned out repeated, almost as soon as they were installed, then stopped working altogether, some melting and corrrosion in sockets. All other rear lights fine. Replaced rear light circuit boards ( about $25 each) and new pigtail harnesses (about 50$). Problem solved, for now

Wiring must of got hot in the area around a light socket. Replaced tail light from wrecking yard.
looks like previous owner applied some Vaseline to the socket, replaced after finding out light was not working. did not light up until I put some pressure on the bulb, then it worked for about 10 miles. the next trip I noticed it was out again. after that trip I noticed the area where the break light was not working seemed warm to the touch. this makes me think there is some shorting going on.
