Description and operation

Lamp systems

Each vehicle is equipped with various lamp assemblies.

A good ground is necessary for proper lighting operation. Grounding is provided through a separate ground wire.

When changing lamp bulbs check the socket for corrosion. If corrosion is present, clean it with a wire brush and coat the inside of the socket lightly with mopart multi-purpose grease or equivalent.



Headlamps on the Durango are modular in design.

The turn/park lamp module is incorporated into the headlamp module. The module contains four bulbs; a dual filament headlamp bulb, two dual filament turn/ park bulbs, and a side marker bulb.


Headlamps and parking lamps are controlled by the headlamp switch. The multifunction switch mounted on the steering column controls the high beam function, and the turn signal function.



The headlamp switch modules located on the instrument panel. The headlamp switch controls the parking lamps and the headlamps. A separate switch in the module controls the interior lamps, and instrument cluster illumination. This switch also contains a rheostat for controlling the illumination level of the instrument cluster lamps.


The headlamp switch has an off position, a parking lamp position, and a headlamp on position. High beams are controlled by the multifunction switch on the steering column. The headlamp switch cannot be repaired. It must be replaced. Refer to Group 8E for removal and installation procedures, and Group 8W for wiring.



The Daytime Running Lights (Headlamps) System is installed on vehicles manufactured for sale in Canada only. A separate module, mounted on the cowl, controls the DRL.


The headlamps are illuminated when the ignition switch is turned to the ON position. The DRL module receives a vehicle-moving signal from the vehicle speed sensor. This provides a constant headlamps- on condition as long as the vehicle is moving.

The lamps are illuminated at less than 50 percent of normal intensity.



The taillamps on the Durango are mounted at the rear of the vehicle, outboard of the rear hatch and integrated into the lines of the vehicle. The taillamp module contains a housing, lens, and three bulbs.

Dual filament bulb is used for tail, stop, and turn signal operations. A separate bulb is used for back-up illumination.


Tail lamp functions are controlled by the headlamp switch. Turn signal operations are controlled by the multifunction switch. Stop lamp functions are controlled by the stoplamp switch. The back-up lamps are controlled by the back-up lamp switch on the transmission.
