How to Repair an Isuzu Window Lift Mechanism

by Don Bowman

An Isuzu window lift mechanism is a single-post, cable-operated window regulator with a separate window motor. The window motor operates the cable by using a gear. Before working on a faulty window motor or regulator in your Isuzu, test the operation of the remaining windows. Also, listen for the motor operation when activated; this will identify whether it's the motor or the regulator that has failed in the vehicle.

Remove the two Phillips screws in the armrest region. Take the Phillips screw out of the plastic cover in front of the interior door handle. Insert the common screwdriver between the door panel and the door, and pry the trim fasteners from the door.

Disconnect the electrical connectors from the window and door lock switch. Pull the moisture barrier from the door enough to gain access to the window regulator. Disconnect the electrical connector at the window motor.

Remove the 10 mm bolts securing the window motor to the regulator, using a ¼-inch drive socket. Remove the motor. Loosen and remove the two 10 mm nuts securing the regulator to the bottom of the window glass. Raise the glass by hand, and insert the common screwdriver vertically from the top door ledge; this will act as a wedge and prevent the window glass from falling.

Remove the four 10 mm nuts securing the window regulator to the door. Pull the window regulator out of the door.

Install the new window regulator into the door, and secure it with the four 10 mm nuts. Hold the window glass and withdraw the common screwdriver from the door. Lower the glass carefully to meet the window regulator-lifting channel. Insert and tighten the two 10 mm bolts to secure the window to the regulator.

Install the window motor, rotating the motor slightly as needed to mesh the gears of the motor to the gears of the regulator. Screw in the bolts and tighten them. Connect the electrical connector to the motor. Install the remaining parts in reverse order of removal.
