Odd driver window problem

[dra2650]

First noticed problem was the widow would change direction when opening or closing. Usually re-opening when trying to close.
Sometimes struggles to close and needs push assist.
Sometimes won't open (like a dead switch).
Sometimes has no problem.

What could cause this?

thanks

Clean the rubber channels the glasses edges ride in.

For best results remove door panel to access completely.... but, you could try just cleaning the upper portions.
