Turn signal stays on

Hello. Problem is that when pushing the turn signal arm left or right to make a turn, the turn signal indicator on the dashboard flashes quickly and prompts me to check the front left/right turn signals. The left turn signal does not blink in fact it stays lit even when car is turned off, and the right front signal does not blink at all. The rear signals both work fine. Tried replacing the front bulbs, no change. Had the fuses / fuse box under hood checked, no burnt out fuses there.

Thanks

Hello,

There is a relay that could have gone bad, also I would try cycling the hazard switch which will clean the electrical contacts. Here are some wiring diagrams (BELOW) and a guide to help you do some testing. Also check all of the fuses.

Please run some tests and get back to us so we can continue helping you.

Cheers, Ken

My front passenger side blinker (in the head lamp, not the side marker) does not work. The bulb will come on with the park lamps but the blinker and hazzards do not. All the other blinkers are working, and they do not blink fast like when a bulb is out. I checked the fuses under the dash and next to the battery. I also changed the bulb and no luck. Any ideas?

Have you checked to see if there is power to the socket which would indicate the socket itself is bad and not connecting with the bulb properly?

I didn't check it, but the bulb will light up with the parking lamp switched on, just not the flashers. So it gets power for at least the one function.

Check to see if power is there. Using a test light, make sure you have a good ground and see if it lights with the flasher only.
