How to Repair a Toyota Corolla Power Window

Repairing a malfunctioning power window in your Toyota Corolla depends primarily on the year of your model. The window itself is comprised of the main components -- the glass, regulator, wiring and switch -- but their exact installation depends on the year it was made. Some parts may not be easily accessible on some models. Check with your mechanic to see how easilyyou can perform work on your own windows.

Instructions

    1

    Pry the control switch for the window out of the door trim panel using a trim stick or a similar flat tool. The switch plate is normally located on the armrest.

    2

    Remove all small trim panels near or on the main panel -- this can include the mirror panel, door handle and armrest panels -- and then unscrew the door panel with your screwdriver and pry the panel off the door with a putty knife or similar tool.

    3

    Remove the door access plate that covers the access hole if needed. There are usually three screws in a triangular pattern.

    4

    Reconnect the power switch to its electrical connector and lower the window, if needed, to access the window glass bolts. Remove the bolts with your wrench and push/slide the glass out the door.

    5

    Inspect the wiring; disconnect it from the regulator, feed it out the door and replace it if the wiring is damaged.

    6

    Unbolt and remove the window regulator from the door. On many newer models since 2003, the regulator is a more permanent fixture in the door and will require professional assistance.

Installation

    7

    Install the replacement window regulator in the door using its bolts. Connect the electrical connector to the regulator.

    8

    Slide the glass (old or replacement) through the slot into the door and within the regulator channels and bolt it in place.

    9

    Reconnect the access plate to the door with its screws if needed.

    10

    Connect the door trim panel with its clips and screws and then reconnect the other trim panels. Reconnect the switch plate with its electrical connector.
