rear demister

[deanster12]

when the car starts it starts alright and idles smooth but when i press my rear window demister button on the car starts to shake and judder as if misfiring or wants to cut out this is doing my head in especially on cold mornins when theres a shit load of ice on your back window.

Just boil up a kettle and pour hot water on the window. So much quicker :A:
