I finally had enough of the molasses-in-January speed of my elec. windows. If this quik-fix has been posted, I apologize. I popped the panels off, tore off all the factory plastic, and greased everything I could find with the same grease I use on the boat trailer. Like brand new! Since I ripped the old plastic off, I also took the opportunity to install the DynaMat I've procrastinated over...all door panels and windows. FYI..low tech solution. ...Kit.
