How to Replace a Window Motor on Vehicles

by Contributing Writer; Updated June 12, 2017

The Vehicles Chevy Vehicles power window system relies on a window switch, window motor and window regulator to operate properly. If any of these three components fails, it renders the entire system inoperative. The motor transforms the electrical energy sent to it from the window switch into kinetic energy it uses to turn a gear on the window regulator, which moves the window itself. If you have entry-level auto-repair experience, you can tackle this task and get back to enjoying the convenience of power windows in your Chevy Vehicles in about an hour.
