My son has a 1997 Tahoe LT and the door buzzer will stay on even when the car is running with the doors closed. All of the lights including the door open and dome lights will not turn off unless I hit the the dome override switch. I had a friend put new speakers in his car and was wondering if the problem may be in the door panel. Does anyone know a quick fix on how to stop the buzzing so I can at least have him drive it to school prior to fixing the entirre problem
