Re: Power Window Won't go down!
My guess if tinting makes this problem worse, perhaps the glass is getting so hot that it is acting like a bimetal spring. Unequal heating even by a few degrees across the thickness of the glass could add up to a fairly strong spring action.
This results in the window being locked into place, especially since modern power windows have torque sensors that shut the motor off when it gets too large of a load.
I don't think you can blame any particular brand of car for this. I wouldn't be surprised that most power window motors come from one of a half-dozen or so parts suppliers all over the world.
