Check all fuses first. If all of them are good, you probably have a bad multi-function switch. The only way to correct that is to replace the switch. The switch is at the end of the turn signal lever inside the steering column.
That is a good thing. You want the turn signals to work.
hazards and turn signals have separate flashers. replace flasher for turn signals
Check the fuses and the flasher unit.
There are two flashers, one for the hazards and one for the signals.
For most vehicles the hazards and signals are two separate circuits, they have separate fuses and separate flashers. Check your signal light fuse and signal light flasher.
Turn signals and hazards are two separate curuits. Check/replace your signal light fuse and flasher.
be cause your bulb is blown out
If the 4 Ways/Hazards are disconnected then neither will work the park lights nor the turn signals.
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.
If the turn signals are inoperative check the hazard switch, if the hazards don't work replace the hazard switch, the signals will start working. if the hazards are ok ,the turn signal switch may be bad.
Defective flasher relay.
