1998 Pontiac Trans Sport Question: Brake light signal light problem
It sounds like what you have is a "feedback" issue caused by a bad electrical ground. Most of the electrical circuits in our cars use the metal chassis to complete the "ground" side of the circuit. When the ground side is not functioning correctly the electrical current has to go somewhere so it flows backward through the circuit looking for a path to ground. Check both brake light bulbs, sockets, and grounds for proper operation. Repair any faults and then recheck the operation of you lights. - Russ
The tail light connectors are not as heavy duty as they should be. The connector heats up and melts the plastic and the voltage is not correct causing the problem. - Visitor
My wifes van is doing the same. Have you figured out the solution yet? I have replaced ALL the bulbs and still doing it. Very frustrating. - chewie1
