The turn signal on your vehicle is mounted on the front and back of the vehicle, on both the left and right sides. Once your turn signal is activated, the left or right side lights flash to indicate which way you are turning. Some modern cars have turn signals on the driver’s and passenger’s side mirror as well.

How to Check Your Turn Signal

If you suspect one of your turn signals is bad, you can check it without any equipment. A bad turn signal is normally indicated by a quick flashing light when you put the blinker on. To check the signals, turn your vehicle on and put it in park. To test the right turn signal, push the blinker to upwards. With the vehicle still in park, get out of the car and see if the signal is blinking both in the front and in the back and on the right side. Next, get back into the car and push the blinker all the way down, indicating a left turn. Get out of the vehicle and check to see if the light is blinking both in the front and in the back on the left side. If one of the lights is not illuminated or is blinking rapidly, you may need to replace the bulb.

Potential Problems With Turn Signals

If the turn signals light up, but do not flash, it is time to replace the flasher. If there are no turn signals on either side, check the fuse as it may be defective. Another problem is both turn signals on one side not working. This could indicate bad bulbs or bad ground in both housings. While testing the turn signal, if one signal light does not illuminate, check for corrosion in the socket, replace the bulb, and check for poor ground at the socket. It is a good idea to have YourMechanic look at your vehicle in case the turn signal switch needs to be replaced.

Basic Turn Signal Laws

While driving, you are required to use your turn signal. If you fail to use your signal while changing lanes, turning, or making other maneuvers while driving, you may get pulled over and be cited by a police officer.

Turn signals let other motorists know your intentions while driving a vehicle. If one or a few of your bulbs are not working, consult a mechanic in case the problem is more complicated than just changing a bulb.

Ford Focus - Turn signal light is not working - Chandler, Arizona
Julio did a great job with diagnosing my rear signals and brake lights problem. He was very personable and easy to work with and explained things thoroughly and gave me options. He also advised me of other maintenance needs and prioritized them without trying to push me to fix things that weren't urgent problems. He ruled out the fuses or switches being issue and correctly identified the problem as coming from the bulbs (I didn't realize the bulbs could be multi-function so had not checked those). I highly recommend Julio Pereyda.

Pontiac Firebird - Turn signal light is not working - Euclid, Ohio
Matt kept me apprised of his est time of arrival. Upon arriving he immediately got to work diagnosing the issue with my repair. He pointed out to me in great detail the problems of my repair, he gave me a quote and we've scheduled the actual repair for next Saturday that coincides best with my schedule. He recommended a inspection before submitting the repair. So I am very pleased with the service Matt has provided so far. I will submit an updated review next Saturday after my repair. This is my 2nd time using the "Your Mechanic" service and just like the 1st time, this service is a "Godsend" not having to spend an entire day off sitting in a repair shop and getting an accurate assessment of my repair and an affordable price. I have already referred "Your Mechanic" to my friends and family after my 1st repair with them last year. But I will keep singing their praises for as long as they keep up the level of service I've experienced so far. Thank you once again.
