Why will the turn signals work only if flashers are on but the flashers will not work at all?
The relay that handles the turn signals is separate from the relay that handles the hazards.
Most likely you have a burned out turn signal relay. Most likely the relay is located in your fuse panel and is a very inexpensive item to replace.
turn signals and hazards have separate flasher cans both look the same and are generally in the fuse box replace the hazard flasher can. they cost about 2 dollars at auto store
There may be a lamp with one of the turn signal elements burned out. If one is burned out turn signals may not work even though the lamp appears to be working when the lights are on.
Otherwise replace emergency flasher or possibly turn signal switch in steering wheel.
I had the same problem on my 2003 Saturn L200. When I cycled the Hazard Signal/switch for about 30 seconds, both left and right turn signals once again worked!!
Hazard and turn signals usually use separate flashers, switch the flashers to see if turn signals work and hazards don't, if so replace the flasher you need to replace the blinker flasher unit it is different from the hazard unit they cost about 4 bucks the flasher unit is the big round thing in the fuse panel in the dashboard
What would fix emergency 4-way flasher in a 98 VW Jetta TDI when the outside lights won't flash but the red indicator light on the module lights up steadily and turn signals are normal?
What would cause the turn signals and emergency flashers to stop working on a 2003 JEEP Wrangler X. I checked the fuses and bulbs and they are good.?
If your turn signal flashers stopped working, play with the emergency flasher button on top of the steering column. Our 97 Sable turn signals quit once and luckily I pushed the emergency flasher button in and out many times and the signals have worked ever since. But the emergency flashers don't work, but I can live with that.
