The driver side blinker is not working properly(The turn signal )

I have a 2003 Suburban, Problem with the left turn signal, the blinkers work sometimes .Only happen with the left side. The passenger side works without a problem. I replaced the multifunction switch it and still the same. What else could be causing this?
The emergency lights DO work, and it doesn't seem to be a problem with any of the bulbs

SOURCE: left turn signal turns on emergency blinkers

These functions are all controlled by the turn signal switch, also known as the multifunction switch, this is a common issue you have and will require you replace the switch.

the most common problem is the light boeard in the tail lights usually replace the board full of bulb sockets and that takes care of it but before condeming the board make sure you are getting power to it

SOURCE: turn signals and back up lights dont work.

Test the circuit board wires on the back side of your taillights where the bulbs go in to see if power is going there with the blinker on, if yes replace the circuit board (quite common with these trucks). If there is no power back there check your flasher relays for each turn signal, assuming they dont click off and on when you tip the turn lever. if all else fails, head for the multifunction switch behind your steering wheel inside the column that your turn signal/wiper/cruise control lever is connected to.

SOURCE: No turn signals or emergency blinkers

I had the same problem twice before. Solved it the same way both times. In my case it was the Hazard switch at the top of the steering column. It was stuck. I knew it was that because the signal lights had been functioning perfectly until I parked my car alongside the road with the hazard lights on to do some nighttime fishing and sip a little white lightnin'. (just kiddin' about the white lightnin')

When I got back in my car to go, I turned off the hazard lights but I had no turn signal lights! So I kept pushing that hazard button up and down for about 30 times with my left turn signal arm down until it started working again. So after having this happen to me twice, I learned a valuable lesson: Don't ever use hazard signals in this car.

Have you checked the contacts to make sure they have good contact with the bulb base? I have a 1995 Ford Contour. The turn signal went out. I replaced the bulb and it would work when it wanted to. I checked the contacts and sure enough they weren't making good contact with the bulb. I took a screwdiver and slightly bent the contacts a little. It has worked good ever since.

SOURCE: Rear blinker does not work need to access bulb

Your rear bulb is burnt out if you say the front one is working .. the speed up of flashing means your bulb is bad.. you might have to get in the trunk and unscrrew those hand wing nuts and push that tail light outward to get to the bulbs ... thanks Jerry and holler if you need more.

Saturn 2002 VUE Turn Signal not working properly.


You need to check your left side turn/park lamp bulbs for correct part # & installation.If that checks out you deffinetely have a ground problem.When you have other lights blinking with you turn signals you have either a bulb incorrect or a bad/poor ground.If bulbs check out check your forward lamp harness ground.Hope this helps

Left turn signal is blinking fast,where is the relay located at?


You did not say if the right signal blinks ok or not. Assuming it blinks like the left, the best way to find the blinker is to leave the engine off but the key switch on and turn your blinker on. Now LISTEN and you should hear the clicking. If the right side blinker is normal then you may have a bad turn signal bulb or ground to one of the signal bulbs. An easy way to check your turn signal bulbs is to turn on your emergency flashers and look at the bulbs, they all should blink at the same time and with the same brightness. Good Luck

Blinkers not working


Did you check the bulbs? If one bulb is burned out, the blinkers won't word on that side. You could have one bulb burned out on each side. Start the car, put left signal on. Check front and back lights. Is one light on but not blinking? If that's the case, the light that's not on at all is burned out and has broken the circuit so the good light stays on and won't blink. Check the other side. You also have a 'flasher' , actually 2. One for emergency flashers, one for the turn signals. It could be that the turn signal flasher is shot. You just have to unplug it to remove. It's probably located near the fuses. good luck countrycurt0
