Auto Up Operation does not Fully Close Power Window (Jam Protection Function is Activated): Description

WARNING: This page is about a different car, the 2012 Lexus LS 460. However, it is still accessible from the selected car via links, so may be relevant.

This symptom may occur to all door windows.
If the door glass or the power window regulator motor does not operate smoothly, the jam protection function may be triggered automatically, resulting in the AUTO UP function being unable to fully close the window.
