Why does my blinker sometimes not work?

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. This problem requires advanced knowledge of wiring to fix.

If both rear turn signal lights are not working correctly, it’s most likely due to an electrical relay or fuse that supplies power to the tail lights. However, if it’s a fuse, it’s likely that the parking lights (when you turn on headlights) and/or hazard lights are also not working.

Why are trailer lights not working?

Because the most common reason for trailer lights not working properly is a bad or missing ground, check the trailer’s and truck’s ground connection first. A poor ground often becomes the culprit when only some lighting functions are working and when lights go out when you push the brake pedal.

Why would a turn signal stop working?

Most experts will tell you that if your turn signal isn’t working, it’s because of one of two reasons. Either your bulb is burnt out, or you have a faulty turn signal relay. A turn signal bulb, like other broken lights or worn out bulbs, is easy to replace.

Why is your turn signal blinking fast?

The main reason why turn signals start blinking really fast is a bulb failure in the head lamp. When the bulb fails to work properly because it has been damaged or broken, the resistance switches adapt to the sudden change by making the light blink repeatedly in a very fast manner.
