Ok, ive been having some problems with my windows..... first the drivers side used to roll up and down , but got slower,,,and slower and slower. Now it dosent roll up all the way,or go at all....it just sits there The BACK window,,,, it rolls down ,(real slow,) but dosent roll up all the way. ,,,again the driver side got slower and slower,,,,,,,and stopped. And the back is starting to go real slow, and dosnt roll all the way up,but goes down slow. Is there something i can grease up??
