It was my first icy start yesterday and I noticed that the wing mirrors were not de-icing.
Any thoughts on why this is?

Also the passenger side air vent is having a problem. All of the grills inside have come loose from one another. Is there an easy way of fixing this before I start hitting it with a hammer. Range Rover Autobiography 5.0SC

Just about to go and have a play to see if I can find the problem. Does anyone think it could be a fuse?
I read the manual to try and find where the fuse is but it seems there are more than one? Does anyone know which fuse it might be? Range Rover Autobiography 5.0SC

Cheers Justin.

It would have been a good fix but it seems to have caused another problem?
Now the wing mirrors fold in and stay in but now my front passenger indicator doesn't work
I have checked the bulb and it's fine.
Anyone have any idea's? Range Rover Autobiography 5.0SC

Quote:

The door mirrors operate when the ignition switch is turned to the 'auxiliary' position.
Operation of the door mirrors is carried out by door modules located in each front door, in
conjunction with the Body Control Unit (BCU).
The BCU can store up to three mirror positions in its memory, which it transmits to the door
modules via the peripheral (P) bus. The BCU also initiates mirror heating if the outside
temperature is between -10 °C and 35 °C.
If reverse gear is selected, the passenger door mirror will automatically lower to enable the
driver to gain a better view of the kerb. When reverse gear is deselected, the mirror returns
to its original position.
For a detailed description of door mirror operation, refer to the Exterior Fittings – Door
Mirrors section of the Description and Operation Workshop Manual.
