How to replace turn signal and hazard light flasher on a 2002 durango

What fuse are you pulling ?

Hazard Lamps
The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.

Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.

Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.

According to the manual, there are two fuses for the turn signals/hazard lights, Fuse D in the power distribution center (in the engine compartment), and Fuse 10 on the Junction Block (left side of the dashboard assembly). Also on the junction block is the combination flasher unit. If these all check OK, you'll need to check the wiring and connectors from the junction block to the combination switch on the steering column, and the combination switch itself.

There are two separate flasher blocks, one for hazards and one for turn signals, listen for the clicking with hazards on there usually right next to each other, when you find it swap the flashers around and see if the turn signals start working and the flashers quit.. Otherwise you could also be looking at a turn signal switch problem

A mechanic would check for voltage at the multi-function switch in the column. Those three circuits go thru the turn signal switch.

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.

Models from 98 on use a combination flasher. This flasher is mounted either on the front or on the back of the junction block.
The combination flasher is a smart relay that functions as both the turn signal system and the hazard warning system flasher. It is designed to handle factory-fitted equipment. If aftermarket equipment is added to this circuit (such as trailers with lights), the flasher will automatically try to compensate to keep the flashing rate the same.

1. The flasher contains sophisticated internal circuitry that cannot be tested with conventional equipment. Substituting a new unit for a suspected defective version is the easiest test.
2. On air bag-e quipped vehicles, disconnect the battery negative cable(s) and wait two minutes from the air bag capacitor to discharge.
3. Remove the junction block cover. If the flasher is accessible, grasp and pull the flasher from the fuse panel.
4. If the flasher is not mounted on the outside of the junction block, remove the steering column cover from the instrument panel. Reach through the opening to access the fuse block on the back of junction block. Pull off the flasher.
5. Inspect the socket for corrosion or any other signs of a bad contact.
   

To install:

1. Install a new flasher in the connector.
2. Install the fuse panel cover.

Hope helps (remember to rate and comment this answer).

check the flasher some times ther is one for the 4 ways and for the turn lights

there are two different relays for flasher and turn, I would check the turn signal relay, if seems good I would check the switch.

Check the combo flasher,both the hazard and turn signals work off this two part flasher (one piece)

The flashers are timed thru the hazzard switch. The hazzard switchneeds replaced. As for your other problems, has to be a body control module. The dealer will need to program this peice, as it holds the miles.
