What is wrong with my turn signal?
You may be dealing with bad bulbs, a bad flasher relay, a faulty turn signal switch, or a bad wire or connector between the flasher unit and the turn signal switch. First, check the bulbs to see if they are still in good shape: No darkened areas or damaged filaments.
Why is my turn signal switch not working?
The turn signal switch is the device near your wheel which controls your signal. A faulty signal switch can’t send a signal to the blinkers to work. Sometimes the problem may lie in the wiring, or in the switch itself. If the problem lies with the switch then it’s likely getting stuck in position due to the clock-spring.
How can I diagnose a turn signal problem?
Diagnose Turn Signal Problems. The flasher contains what’s known as a “bi-metallic spring,” which is a flat strip with one kind of metal on one side, and another kind on the other. The flexible strip connects the electrical supply from the box to the wiring that goes to your turn signal switch.
What causes turn signals to go bad on a car?
