Typical of one of the things you can't really test picking up a car on a warm morning… -3 today and frost on the car. Pressed the rear screen heater button and the little icons illuminated for the scrceen and mirrors. Mirrors seemed okay, no apparent heat from the rear screen matrix.
Anyone else come across this? I'm thinking it is likely a break somewhere on the matrix, as it will be a single fuse for the mirrors and rear?
