Flasher relay bad. This is a separate flasher relay from the one controlling the hazard lights.
Start by identifying the cause of the problem, then figuring out how to repair it is easy. It'll either in the power supply, the switch, or the wiring. Start diagnosing.
Probably the turn signal flasher
I hope you are not driving this vehicle with so many faults? Obviously an electrical system problem. Start with the obvious thing, fuses, then check all the bulbs by removing them and looking at the filament wires and the base to see if they are broken or corroded. Finally check the flasher both regular signals plus the hazard flashers, and replace as needed.
Probably the Electronic Flasher. These ,when the fail,will allow the Signals and/or hazard lights to work intermittently. The flasher is the same for both the signals and hazards.
Your fuse box should be located above the glove compartment. However, I believe the signal flashers are located under the hoodin a larger fuse compartment on the passenger side of the engine compartment.
There is two flashers involved, one for the signals and one for the emergency flashers. Perhaps you changed the wrong one.
Check bulbs - they are double filamented with the smaller beign for brake and turn signals Check the sockets for power and ground Could be an open wire under bed Possibly a problem insdie the steering column
Check the fuses first of all. I think the Durango has two flashers as well, one for the hazards and one for the signals so it could be a bad flasher.
Possible causes include broken wire, failed switch, blown fuse, faulty flasher.
I have a '92 Dynasty and the turn signals quit working. The manual said that this happens because of a burnt-out bulb somewhere. Did you check those?
may have a bad signal switch,or may be a blown fuse
No
