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.
