How to Fix the Power Window on a Chrysler

Save

Chrysler cars and trucks are manufactured with motor-driven window regulators, which raise and lower a pane of glass within a door. Several issues with the power window can lead to its failure, including wiring, fuses and damage. The average backyard mechanic can fix a power window in a Chrysler in about an hour.

Things You'll Need

  • Socket set
  • Screwdrivers
  • Check the fuses for melted filaments. The fuse panel is located at the driver's side kick panel for most Chryslers. Replace any blown fuses.

  • Check the other windows for proper operation. If only one window does not function, or is extremely slow, then the motor could be damaged. The switch should be checked before replacing the motor, and the procedure will follow.

  • Disconnect the positive terminal on the battery by turning the bolt counterclockwise. Set the loose terminal aside, but not touching any metal.

  • Remove the power window switch assembly by prying the edge up with a screwdriver and pulling the unit firmly from the panel. Once the assembly is out, disconnect the wiring harness adapter plug by pulling it apart. Set the switches aside. Some models may have multiple switches, which can be interchanged with the suspect switch to check for operation. Reconnect the battery temporarily. If the window operates properly with the ad hoc switch, replace the bad switch at this time. No change in operation indicates a bad power motor.

  • Turn the interior door handle screw counterclockwise to remove it.

  • Turn the arm rest bolts counterclockwise, if applicable. This will free the hardware connections to the panel.

  • Pull the panel free from the door metal, disengaging the pop rivets one by one. The plastic rivets that hold the panel to the door can become brittle as they age and may require replacement.

  • Disconnect the motor from the wiring harness by releasing the catch on the adapter plug and pulling it apart.

  • Turn the motor mount bolts in a counterclockwise direction until the motor is free. The motor can be pulled straight out, away from the window regulator gears.

  • Replace the motor with a new unit, then position it back onto the window regulator gears. Turn the mount bolts clockwise until snug. Reconnect the wiring harness by pressing the adapter plugs together.

  • Press the door panel against the metal door until all pop rivets have engaged into their holes. Some rivets may have trouble lining up, so work the panel around until all of the rivets are tight.

  • Turn the arm rest bolts and the interior door handle screws in a clockwise direction until they are snug.

  • Replace the power window switch assembly by pressing the adapter plugs together, then seating the assembly into the panel's opening. Most types of switches used by Chrysler simply press into the panel.

  • Reconnect the positive terminal on the battery by turning the terminal bolt clockwise.

Tips & Warnings

  • Use lithium grease on the joints of the window regulator to lubricate them.
  • Use caution when working on a vehicle's electrical system.
