Hi,

I recently developed a problem with my blinkers. They don't work; there is no flashing, and no indication of flashing on the dash. At the same time, my cruise control, hazard lights, and brake lights stopped working. I replaced a few fuses, now the cruise control, brake lights work. I sprayed wd-40 on the hazard light switch, which started to work. Nothing I did would get the blinkers to work. I replaced the multi-function switch, which also didn't help. Could this be a relay problem or grounding issue?

 

the hazards and the blinkers have two different relays. one on the front of the fuse box and one on the back.

 

Thanks for the response. Are you referring to the instrument panel fuse box or the power distribution box?

 

the fuse box is inside the cab.

that is the one i am referring too.
