How to tell If turn signal switch is bad?
Symptoms of a Bad or Failing Turn Signal Switch
- Turn signal indicator continues to blink when the steering wheel returns to the center.
- Turn signal lights don’t continue flashing unless turn signal lever is held down.
- Left or right turn signals or the Hazard Warning Light not working properly.
Is there a blinker fuse?
The flasher module provides power to the turn signal system. The fuse connects to this device through a strip of lead. If this lead is damaged, then it will likely affect the exterior blinkers.
Why do the turn signals quit working when the lights are on?
The reason the turn signals quit working when the lights are on, is that a 12-volt signal is now being sent down the opposite wire, which was acting as a ground before. Once the lights are turned off, everything will work fine again.
Is there a turn signal for both left and right?
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.
What to do if your turn signal switch is bad?
You may be dealing with bad bulbs or a fault between that side of the circuit and the turn signal switch itself. First, check the bulbs to see if they are still in good shape: No darkened areas or damaged filaments. Then, check the sockets for corrosion, wear or damage. Confirm the ground and power connections are working properly.
How long do turn signal light bulbs last?
Light bulbs die – eventually, they all do. Turn signal light bulbs should last for at least a few years. Most people will have their turn signal lights last for the life of the car. It all depends on how much you drive and how often you use your turn signals.

Is there a way to test a turn signal?
Only the Front Right Turn Signals don’t work. Or only the Rear Right Turn Signals don’t work. Since the turn signal switch isn’t cheap (at your local auto parts store expect to pay about $150 US), it’s best to test it and make sure it’s really bad.
