Many models of the Dodge Durango and other vehicles use power windows in the doors that are operated by switches. Repairing a power switch that doesn't work can be a matter of replacing the switch itself or changing the wiring harness. How much work you have to do depends on exactly what needs replacing. This process can also vary depending on the exact year of your particular Dodge Durango.
Disconnect the truck's negative battery cable at the terminal, loosening the clamp's nut with your wrench.
Pry out the power switch control from the inner door armrest using a trim stick and disconnect the electrical connector in the rear. Skip to Step 8 if this is all you need to replace.
Remove the screws for the door's inner trim panel if you need to get to the switch's wiring --- the Durango's screws are usually behind the door handle, behind the pull handle, up near the mirror and along the bottom edge.
Pull the panel up and off its clips to remove it, then peel back the plastic water shield.
Disconnect the wiring electrical connector from the regulator's motor and feed the wiring out the door.
Connect the electrical connector for the new wiring to the window regulator motor and feed it up toward the position of the control switch.
Press the water shield into position with its own adhesive and reconnect the inner trim panel with its clips and screws.
Connect the wiring to the window switch plate (old or new) and insert the switch controls in position on the trim panel --- usually above the pull handle and to the side of the main handle.
Reconnect the battery cable.
