How do I fix the turn signal? The driver side signal light does not blink, it stays lit, even after the the ignition is turned off! The passenger side turn signal works fine.

Could be a problem with the flasher relay , I'd start with that

Not the flasher. It's the turn signal switch that has shorted.

have a load test done on the battery as there may be a dead cell Have an auto electrician check the reason for the indicator light staying on

Looks like a blinker relay stuck.

Plain and simple...Your turn signal circuit is shorted to your headlamp circuit. What USUALLY causes this is an incorrect light bulb has been installed in the vehicle or the light bulb was installed incorrectly. There are other possible causes of these circuits being shorted together, but 99 out of 100 of the times that I have seen this it is either because somebody just replaced a bulb or a bulb socket melted somwhere on the car. Be sure to check both the front AND rear bulbs.

did you check ALL the bulbs for ALL the lights?

What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.

If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.

Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.

If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.

But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.

This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.

Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.

you need to replace the rear driver side light bulb. it will fix the problem.

You have a shorted bulb. Replace the bulb.
