My toyota 92 pickup truck turn signals don't work;

try turning on the hazards, if they work then it is probably the signal flasher gone bad. these are 2 different flashers they look the same. you didn`t say what car/year you have so I can`t tell you were it would be located. if the hazards don`t work check fuse if this is good then it could be the turn signal switch that is bad.

Not one a 91. You should have a fuse for the turn signal and on for the hazard. Also you will have two flashers for it.

bad multi-function switch

Check the switch and may be on seperate flasher unit

you may have a blown fuse. that would be where i would look first.

you don`t say but do the lights work either on the front/back on both sides.if not then it may be a fuse that needs replacing or need a bulb replacement.if the lights work but don`t flash then it sounds like a signal flasher problem.the flasher is located in the fuse panel under the dash on the drivers side.if the hazard flashers work then turn them on to find the hazard flasher by the fuse panel then you will know what the signal flasher looks like and change the signal flasher.make sure you change the one for the signals and not the hazard one.if the hazards work then i would say the signal switch is good as the hazards work through the same switch.

Yes, the problem is the turn signal flasher is defective. You can has two flasher relays. One for the turn signals and one for the hazard lights. That is why the hazard lights flash and the turn signals do not. Replace the turn signal flasher relay located on the drivers side of the steering column, mounted behind the instrument cluster in the convenience center. They are both mounted in the same location so turn on the hazard lights and the one that you put your finger on that is not clicking is the turn signal relay.

if turn signals work, check flasher for hazard lights, you can swap with turn flasher to test

The hazard lights has it's own flasher, change the flasher for the turn signals and see if that works. To find out which flasher it is, put on the hazard lights, and put your finger on the flashers, which ever one you don't feel clicking is the turn signal one.

Suggest you change hazard flasher 'can' first, then go to the hazard switch. I'm betting it's the flasher can.
