Could be flasher Common problem on this vehicle Flasher is part of the hazard warning module
How do I replace turn signal on a 1992 Chevrolet caprice classic I want to learn how to do it myself
either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.
There is a faulty ground wire in one of your tail lights or front parking/clearance lights.
An open ground or a short to ground when the signal is on. Usually a bad bulb.
a repair guy needs to do that for you.
Headlights? Brake lights? Tail lights? Signal lights? Courtesy lights? Dash lights? Check engine lights? Need more info please.
If neither signal light works, the flasher may very likely be the problem. The hazard lights and the signal lights work off different flashers.
No it is not illegal, as long as you have operational tail lights, brake lights, signal lights and a plate light.
Try your fuses
194 For side marker/front, 1157 for front and rear signal/park lights
Short circuit , maybe ????
turn signal switch needs replaced!
