The window regulator on a 2001 Oldsmobile Alero is a cable-type assembly. The cable is notorious for breaking pulleys and twisting. The motor and regulator are separate parts but can be purchased as a complete unit. To remove and replace the motor, you must remove the regulator from the door. If you can hear the motor operating when the switch is activated, the regulator is bad. No noise from the motor or intermittent operation is indicative of a bad motor.
