Both turn signals work when they want to. The hazzard lights work just fine. All bulbs are great. The turn signal indicator will flash inside the car for a few seconds and then stop. The outisde turn signal lights stop too.

My turn signals work sporadically and have turned off after blinking once or twice and sometimes don't blink at all. What do I need to check to fix it?

I bought the car over 2 years ago and i have always had this problem where the back right blinker would quit working and now it is both i have to take the bulbs out and put the same bulbs back in and it works. But i hate having the inconvience of my back blinkers not working when i am on a busy interstate.

Recently had driver's side rear bulb go out and replaced it. Confirmed correct bulb. Afterwards, turn signals started to work intermittently and are going downhill from there - now I can only get a few flashes before they shut off altogether.

I switch the blinker switch and the blinkers may go off once, either side, then stop. Rarely work without a problem occuring.

All turn signals and brake lights stopped working. Took into Firestone and they diagnosed it with a short in the Signal switch. Replacement was $224.00 for switch, $50 Diagnostic testing, and $20 Safety Check. A whopping total of $338.00.
