Why is my car signal not working?
One Side of the Turn Signal Lights Doesn’t Work.

First, check the bulbs to see if they are still in good shape: No darkened areas or damaged filaments.
Why is my right turn signal not working?
Electricity—takes the path of least resistance. The turn signals on most older GM cars do not have a ground wire. They get their ground through the screws that mount them to the body. There is a good chance that your mounting screws are corroded enough to cause a bad ground at the light.

Although some models use a separate light for the left and right turn indicators, other models use a single light for both turns. If your instrument panel has only one indicator light for both left and right, check the flasher unit. Some vehicle models combine the brake light, taillight and turn signal into one light bulb.

Furthermore, sometimes it is necessary to access the turn signal switch. You’ll have to remove covers and, possibly, the steering wheel.

What happens when your turn signal Flasher stops working?
If your turn signals have stopped working, it’ll be doing one of these things: blinking rapidly, coming on without blinking, or nothing at all.

Why is my left turn signal light not flashing?
Operate the switch to turn the left turn signal light. Back probe the wire that supplies power to the switch; the test light should flash. If the test light doesn’t flash, there is a problem with the flasher unit or an open or short between the switch and the battery power source.
