How to Replace a Volvo Window Regulator

by Susan DeFeo

When windows malfunction, the first suspect on a Volvo is the window regulator. The devices are installed beneath the car doors. Although expensive to fix by certified Volvo mechanics, the removal and installation of a Volvo window regular can be accomplished by the do-it-yourself mechanic.

Remove Old Regulator

Be sure the window is raised to the full "up" position. Then disconnect the negative battery terminal (always do that when working on a car). If the stereo in your Volvo is equipped with an anti-theft device, be sure that you have the activation code before disconnecting the battery, or you won't be able to re-activate the stereo.

Remove both the interior door panel and the moisture barrier.

With the window in the fully "up" position, duct tape it over the top of the door frame to secure it in place.

Disconnect the wiring to the window motor.

Remove the bolts holding the regulator and remove the motor from the regulator cassette.

Installation

Tighten the mounting screws to hold the new regulator loosely into position. Attach the window to the regulator with the old safety clips, making sure they are seated correctly. Reconnect the negative battery cable so you can power the window.

Loosen the front four mounting bolts and roll the window up and down. Tighten the bolts as the regulator seeks and finds its best position. It should take no more than four or five seconds for the window to fully open.

Raise the window to its stopped position. Loosen the stop at the edge of the regulator and roll the window up fully. Check that the stop meshes with the gears. Readjust if necessary, then tighten it in place.

Raise and lower the window to ensure proper operation. If binding occurs, lubricate the run channels with a good silicone spray lubricant.

Install the moisture barrier and the door pad.
