Oldsmobile Alero Window Motor

Beginner's Guide to Troubleshooting Oldsmobile Alero Window Motor Problems

The window motor is one of those parts of the Oldsmobile Alero that we only tend to notice once it stops working. A major component of the Alero's power window system, the window motor drives the window pane up and down the driver's and passenger's side doors. The Oldsmobile Alero window motor is designed to last the life of the car, but weather conditions, factory defects and other factors can cause the motor to break down. In this article, we'll show you some of the common problems of the window motor in the Alero and how you can troubleshoot them.

The window pane won't go all the way in or out

If the glass window pane does not completely rise or lower, the window motor or the pane may be obstructed by a foreign object. This is especially common during the winter months, as ice buildup can cause the gears to lock in place. The obstruction usually occurs inside the car door, so you're likely to have to remove the interior panel of the door to take out the blockage in the window motor.

The motor hums but the window doesn't move

If you hear the motor humming after pressing on the power window switch but the window doesn't budge, one of the gears or the linkages that attach the window motor to the window pane may have come loose or damaged. Check the various connections of the window motor and re-attach, repair, or replace the linkages if necessary. Also, check the window motor gears to see if the gear teeth are in good condition; worn, chipped, or defective gear teeth will not be able to raise or lower the window pane effectively.

The motor isn't working

On the other hand, if the window motor remains silent after the power window is switched on, the motor or one of its electrical connections may gone burned out and need replacement. Use a voltmeter to check if electricity is running through the motor and see if any of the wiring to and from the motor are intact. If the motor and the wirings appear to be in good condition, the problem may be with the window motor fuse or with the power window switch itself.

  • Pointers on Maintaining the Oldsmobile Alero Window Motor 27 February 2013

    The Oldsmobile Alero window motor is one of the more reliable parts of the vehicle and rarely needs replacing, but this doesn't mean that it is completely invulnerable to wear and damage. Because of this, proper care and maintenance is crucial to ensuring the motor's continued smooth operation in your vehicle. So if you want to get the most mileage out of your car's window motor for many years to come, all you have to do is to follow these easy maintenance tips:


    Make sure that the window channels are clean and free of obstruction.


    Over time, the window channels on the interior edges of the car door windows will accumulate debris which, in turn, can restrict the movement of the window pane and impose additional stress to the window motor. So when you're getting your Oldsmobile Alero washed, have the insides of the window channels cleaned as well. In addition, we also recommend checking for and replacing torn and damaged weatherstripping on the windows as these can obstruct the window pane movement as well.


    Avoid parking your car outside during winter.


    While the Oldsmobile Alero is tough enough to withstand a cold winter night, parking the car outside for long periods during the winter months will cause ice to build up inside the car window and hamper the operation of both the window motor and the regulator. In addition, the melted ice and snow can cause the window motor to rust and malfunction. So make sure to park your Alero inside your garage or, if an enclosed parking space is unavailable, at least cover it with a winter-proof covering.


    Check and replace worn seals and gaskets.


    A lot of problems with window motors involve damaged window seals and gaskets. These seals and gaskets help keep moisture and window noise out, but over time they start to come loose from their mounting or get torn from the constant movement of the windows. A loose or torn gasket or seal can hinder window movement and cause unnecessary stress on the window motor, so make sure to repair or replace damaged gaskets and seals as soon as possible.
