ok any ideas anyone, my windshield can not be cleaned, the windshield wipers chatter accross and its impossible to clean, always smears, and streaks, and theres always this film that keeps building up on the inside of the window, i dont smoke and I dont know whats going on, i simply cant clean the windows, and same with the rear window, everything seems fine until the sun hits it, or until headlights hit it, any ideas anyone????
