Drivers side power window doesn't stop when it reaches the top/bottom

I noticed this morning when I was driving to work that if I rolled my window down that the motor didn't stop running when it reached the bottom. I rolled the window back up and noticed it did the same thing and kept running when the window was all the way up. My truck has the auto drivers window so if I push down it goes down on its own but does the same thing and the motor is still running when it reaches the bottom. The other 3 windows are still all working properly. Any one else run into this issue? Any idea what failed in the power window assembly? Thanks in advance for any help!

PS - I did search for this but almost every power window issue I found was for the window not working at all. Couldn't find a thread with it just not stopping.

 

Your master switch contacts could be corroded or dirty. Take apart the master controller and clean the copper contacts.
