2012 Honda Accord ex-l drivers window makes grinding noise when lowering to about 2/3 of the way down, then stops. Will go back up but again makes grinding noise. What could be wrong, would cleaning be first step, like in YouTube videos?
Odds are high that part of the white plastic guide pieces on the window regulator assembly have broken. It is a very common occurrence in all Honda models. The video below attempts to show how to replace the window regulator on the Accord, but the video editing and instructional value is amateurish.
