Who fixes a broken rear demister on a car? Don't tell me its a £1000 replacement glass for a copper line please! I want a professional mechanic/window fitter/sparky to install a copper line x 2 that works or a repair. I need specifics as generally people around here are scared of these repairs or just don't know how to do it. There are companies in USA who supply a stick kit which is elements to attach to original bus bars however the window would need prep work as it has a green tint or film applied at factory.
