In this guide, I will demonstrate how to fix a faulty power window switch on a 2005 Nissan Frontier (King Cab). I did this after the driver-side switch for controlling the passenger window did not work. After further inspection of the switch circuit board, I noticed that the electrical contacts were dirty. After the electrical contacts and reinstalling, the windows worked again.

  1. Approach driver-side door controls. Insert the first trim tool on the right side of the  button molding. Insert the second trim tool on the left, and shimmy it open.

    • Bend this LED back to allow for the removal of the lever.

    • Remember to bend this back into place during reassembly.

  8. Using a thin spudger, carefully pry these two latches off of the lever. Do not pry against the copper rail marked red. Only pry against the area marked green. Carefully wiggle the  lever off, and remove the small metal parts from under the lever. These parts are moving electrical contacts.
