    Caution: Disconnect the power window switch when working inside the driver door. When operated, the Express Up/Down Feature allows the door window to move very quickly, without stopping, which could cause personal injury.

    Notice: Apply protective coating/tape at the insertion point of the small flat-bladed tool in order to prevent damage to the inner door trim panel.

    Important: 

       • When removing a door trim panel or switch plate, the ignition switch must be in the OFF position. This will eliminate the possibility of shorting out the switch if a flat-bladed tool, awl or metal object is used to remove the switch from the harness.
       • Use a flat-bladed tool in order to remove the power window and door lock mounting plate assembly from the trim panel.

  1. Insert the tool at the front of the mounting plate. Press rearward to release the mounting plate retainer and lift up on the front of the plate.
  2. Press down on the rear of the mounting plate to disconnect the tab. Lift out the mounting plate with the switches attached.
  3. Disconnect the electrical connectors.
