^^^^ Your truck looks bad a$$ anymore pics not trying to thread jack sorry about your window problem maybe talk to a tint shop or window shop sometimes in the past with another type of vehicle I had which shall remain nameless the windows would get a little tacky from use and a good cleaning would help them slide better perhaps there's a product the 2 entities I mentioned would know of that also acts to lubricate the affair. Good luck.
