I've got the same problem now. When I turn on the lights, the right rear brake light stays on. None of the other bulbs are out, I re-soldered the connection in the wires going to the RR taillight.

I should also mention that 2 years ago my taillights on both sides went out and I had to remove the connector from the taillight to the wiring harness on each side because all the terminals were corroded. I hard wired all the conections by soldering them and the connections have remained clean. I cut the tape and shrink wrap to make sure.

Where does the taillight ground? In the manual it shows a ground near the taillight and then it looks light each license plate light has a ground. Are these grounds actual grounds to the body or is there a common ground point.

I believe I have a short somewhere that is causing the RR brake light to stay on. Any ideas on places to check for shorts along the wire loom?

I've been working on this problem for a couple of months and now my inspection is due so I need to figure this out. I'd appreciate any help. Thanks.
