In an attempt to help out my brother, he has a 2000 Olds minivan. His wife says sometimes when using the turn signals, both dash indicators flash. She also says the other night, she had no tailights/brakelights. Today, all works fine. Brother had to fly to China on Saturday (AM) and left this in my lap. I am not a wiring wizard but, from past posts, it sounded like a grounding problem to me. Am I on the right track? I took this approach and found nothing except.....the plug in at the right rear tailight appears to have melted slightly. In playing with the plug, it has 5 or six conections and when I press it into the female plug, all is well. When I release the pressure, the symptoms reappear. THe one pin that appears slightly melted is the black (ground) wire pin. Is it possible that this pin and socket have been "arcing" over the past few years and created enough heat to melt? Are the rear lights on this van run in series? When I pull the plug from the right rear, nothing works. Am I missing anything?
