Now answering to Lady J!
Turned on my heated rear screen/wing mirros this morning to clear the condensation off my wing mirros and the driver side mirror didn't seem to clear. Stuck my hand out the window and touched the mirror and it didn't even feel warm. It was working the other week. Anyone else had this? Am sure its only a fuse/wire or something and will get it checked out (i.e. get my dad to look at it!!) just wondered if anyone else had had this and knew what it might be.
