04 Pontiac grand prix turn signal and window problem
1 Answer
For the power windows, there is a circuit breaker. On the hinge side of driver door, should be wiring harness. Probably has a protective rubber boot covering, pull covering back far enough to see wire colors. Yellow wire is voltage, black wire is ground, check them both. Use a test light. Because you open and shut the driver door, so much, sometimes the wire breaks?
