Those are the typical symptoms of a problem with the mutifunction switch. The dielectric grease becomes impregnated with metal flakes, which jumps the contacts inside the switch. The clicking that you hear is the flasher relay located behind the glove compartment. Replacing the switch is not that hard for a DIYer. Some guys have remedied the problem by taking the switch apart, cleaning out the old grease, and applying new grease.

SOURCE: turn signals hazards flasher don't work jeep
I NEED TO LOCATE THE SWITCH WHERE IS IT ?
MY INDICATORS NOR HAZARD LIGHTS ARE WORKING I DONT KNOW WHAT IS WRONG WITH IT CHANGED BULBS BUT NOTHIGN THEY ALL WENT OUT AT THE SAME TIME
SO THERE MUST BE A RELAY SWITCH SOMEWHER BUT DONT KNOW WHERE ?
THANKS FOR HELPING
Hi,
If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.
Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
SOURCE: Where do I install the electronic flasher relay for the turn signals?
If the turn lights come on and don't flash, like mine did, I found the flasher behind the ashtray.If you can't reach it,there are only 4 screws holding the bracket (1/4 in.nut driver) that holds the ashtray.
Turn on the Durango and check each of the four turn signals
to make sure that the bulbs are not burned out. If you find one that has gone
out, replace the bulb and retest the turn signals. When a bulb goes bad on this
circuit, the resulting operation can mimic a bad flasher or one that is
failing.
Locate the combination turn signal flasher and relay. It is
on the left end of the driver's dash. Open the access door and view the
collection of relays and fuses. At the left side of the mounting block is a
larger flasher and relay. This is the combination turn signal flasher and
relay.
Test
the relay by placing you finger on the relay housing and activating the turn
signal. If you have found the right one, you should feel a clicking as the turn
signal blinks. Remove the relay, replace with the new relay and close the
access door
.
Start the Durango and activate the turn signals to check that they each work. The light should turn on and should blink. Also, check the hazard lights to make sure they work.
