Broke my drivers window the other day when was frosty, you can here the window working but wont go down iam hopeing its just the clips, u can push (gently) against the bottem of the window from the outside and it moves from the seal i think water is getting in so that will be first thing i have a look at this weekend, windows still steaming up after new pollen filter fitted so iam hopeing it something to do with the window ?
