I've just fitted a second hand large multi-function screen due to the bottom half of my original not lighting up,everything worked fine until this morning,the climate control and heated rear window aren't working.
I unplugged the screen and tried it again and heater worked fine again,i've just went out to it and its not working again!!
The part number on the back is the same as the old one and all the functions work,anyone know whats causing this?
I plugged the original one in and all was fine so its something to do with the new screen.
