What is wrong if the brake lights in a 1999 Cavalier Z24 do not work but tail directional hazard and center all lamps have been replaced?
The brake light switch may be faulty. This switch is located near the brake pedal and is activated when the brake pedal is depressed. If the switch is faulty, it will not send a signal to the brake lights, causing them not to illuminate when the brake pedal is depressed.
