Product Information
Keeps your windows sliding freely
Pack of 4
This window guide slide rolls along the guide rails inside your door and keeps you window moving smoothly in the up and down position. Small parts like these can break resulting in a complete failure of the window lift mechanism. We recommend replacing these guides when replacing a window regulator for best service life.
The window regulator is responsible for moving the piece of glass inside your door up or down. Window regulators can be manual (hand crank style) or powered (rolled up or down with the flip of a switch). Window regulators can fail after thousands of cycles. The most common failure of any window regulator is the pulley where the cable spins around. Most regulators use a very simple pulley system and due to the material they are constructed from they can fail easily with age.
When window regulators are worn and on the verge of failure there are typically warning signs. You will typically hear a clicking from inside the door panel when the window regulator is being operated. Alternatively, the motor which powers the pulley system may become weak over time resulting in a slow moving window in comparison to others. If you are experiencing these types of symptoms it's highly recommended to inspect and replace the worn parts.
