Auto Down Operation does not Fully Open Power Window (Catch Protection Function is Activated) [08/2016 - ]: Description

WARNING: This page is about a different car, the 2018 Toyota Corolla, 2017 Toyota Corolla, 2016 Toyota Corolla, 2015 Toyota Corolla, and 2014 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.

If the driver door glass or the power window regulator motor assembly (for driver door) does not operate smoothly, the catch protection function may be triggered automatically, resulting in the auto down function being unable to fully open the window.
