The window the past couple days is as smooth as can be and it moves up and down pretty quick. Maybe it needed to go up and down a few times to get the grease I put all over the track on the little wheel and stuff IDK.

 

a guy at the dealer told me as part of maintenance your suposed to lubricate the rubber on the sides of the window with silicone grease. ever since ive been doing it, all my windows go up and down real nice. 0.1 seconds apart from each other.


FYI: the grease on the plastic wheels doesnt matter nearly as much as the sides. its all about friction coefficiants and surface area. plastic and metal will have less friction than glass and rubber and the 2 wheels only touch like 2 square mm whereas the rubber touches about 100 times that.
