Rear demister relay

[craigo]

Hi, having problems with my rear demister! the light doesn't come on but the heated rear window is constantly on, switch does nothing... Does anyone know which relay controls it? Thanks!

HRW relay is not in the engine bay fella as far as I'm aware .
It'll be the bigger relay on the interior UCH .

Yeah it'll be UCH controlled more than likely
