Remove power window switch assy by prying at the ends with a small screw driver while pushing the tip in to release the tabs on both sides.
Remove all screws holding panel on, there should be one by the vent window, one by the arm rest, and there may be some on the bottom of the door panel depending on what style door panel you have. The panel will then pull out and up and slide it over the interior handle. (there are nylon push retainers that hold the panel on) may need to replace some on install to keep a nice tight rattle free door panel. the factory regulator has the window motor attached to it and if its never been changed you will need to drill 3 1/2in holes in the door (you will see small dimples) where the screws that hold the motor to the regulator are on the other side of the sheet metal. If there are holes great, should be 8mm screws. Unplug window motor and wiggle the motor out (keep hand on glass incase it comes down, has taken skin off more than once).
install is reversed.
