My left blinker is doing absolutely nothing. Not blinking fast, nothing. The bulbs are good, and I changed the fuse. For a while it would start working randomly especially if I just left the lever down and waited long enough. Lately though that’s not even working. What’s most likely to be the problem?

Hello,

On this vehicle the turn signals are controlled by the hazard switch. It has built in flasher relay for the turn signal as well as the hazard lights.
The left and the right turn signals are controlled by separate pins, and it is possible to have one side functional but not the other.

I have attached diagrams below for your reference.

Please let me know of any questions.
Thank you.
