1996 Buick Century Question: Replace electrical motor on window
Answer #1DaveJHM February 27, 2011, 03:27Master
Power window motors and / or regulators can indeed fail. To minimize failure, use only original GM parts. Clean and lubricate glass runs on all windows - these channels get dry and have debris build up that causes the windows to become sluggish or even bind...causing abnormal drag and load on the motors.
