Blinkers dont work - 1994 Toyota T100

double, anon posted, why?

You may need to replace the blinker controller, a small device that manages the timing and sequential on/off to the bulbs.

Blinkers and hazards normally work on the same fuse. Sounds like the hazard switch has a problem.Get the hazard switch out and bridge the two connector wires to the switch. If the hazards then work the problem is in the switch.If it don't work you may have a problem in the wiring between the switch and the flasher relay.

its your flasher

I would suggest that it could be the flasher as I had a similar thing happen on my motor cycle. If it does not work at least flashers are cheap.

does the hazard signals work? if they do, then replace all turn signal bulbs.

If the left front light works,then you don't need a fuse you need a bulb for the left rear light.

you didnt say but have you checked the bulbs in front blinkers to see if there bad replace if bad and that should fix your blinker problems

when you use the right turn signal, does it blink faster?. Could it be the bulb holder is damaged or rusty?

It has a bad bulb. Find the bad bulb to fix this issue.
