My 1989 Pioneer Blinkers

My blinkers won't work but my hazard lights do work, the switch in steering column has been replaced twice, it has new flasher, my back-up lights work so it's not fuse. Does anyone know what it could be?

Which flasher did you replace. The hazard one is seperate from the turn one. Do your indicators light up on thr dash.

Replaced both flashers. No indicators do not light up. I'm thinking about pulling steering wheel again and bypassing switch to make sure it not faulty switch.

 Does your heater blower and radio still work? If no it's probably the ignition switch. If yes and you've already changed the turn signal switch, first turn the key to on/run and switch the blinker on. Check for voltage at fuse and at flasher on the fuse box side. You may have a bad connection somewhere causing an open condition, meaning the voltage is not passing through.

 I'm having the same issue but haven't had a chance to look into it yet. I have a feeling mine is caused by corrosion at the fuse box, but I haven't had a chance to verify.

 If you figure it out please post up what you found.

If you have power to going to the turn signal switch from the flasher, it could be a bad hazard switch or the turn signal switch (but you said that has been changed twice).  I would try playing with the hazard switch while the turn signal switch is turned on and the key is in the run position to see if they start working.

Thanks, I will check all that and get back with results.

 Got a chance to work on mine yesterday. Turn signal and ignition switch were good. Turns out i'm not getting voltage from the fuse to the flasher. I'm guessing the connection between the two behind the fuse box is bad. Or could be the fuse holder itself. I put in a temporary bypass for now using an inline fuse and the flashers are working again. I plan to do a dash swap sometime this spring/summer and will dissect the fuse box then.

My MJ was having the same problem. Turns out the socket for the flasher had corrosion on the ternainals. It would either not blink, blink slowly, or stop in the middle of blinking. A small file and come contact cleaner fixed my problem.
