A window regulator is the mechanism inside the door that guides and supports the glass as the power window motor drives it. This Dorman OE Solutions window regulator supplies the regulator mechanism only. The power window motor is not included, so follow the vehicle service procedure for transferring or replacing it.
Signs a regulator may need replacing include a window that moves slowly or sits crooked, glass that drops into the door, or grinding and clicking as the window travels. A failed motor or switch can cause similar symptoms, so diagnose the cause first. If a worn regulator is the problem, this 2004-2009 Toyota Sienna window regulator replaces it.
