Help Needed Please! Rear Screen Demister

Hi all,



Rear screen demister has stopped working and no illumination on the button when pressed. I have checked the 7.5a fuse with a multi meter and its fine, heater is working which it says on net are on same circuit.



Is there another fuse anywhere or can anyone suggest what else I can look at, haven't got a circuit diagram so a bit stuck.



Thanks in advance



Mark
