Hi folks. just wanted to know if anyone else has had a problem with rear window heater. I have a 15plate astra J 2.0l diesel. Periodically when i start the car and scoll through the menu to the top consumers screen it tells me my rear screen heater is on when i have not pressed the button for it. There are no fault codes stored so was wondering if anyone else has had this problem and if they managed to resolve it.
