I cannot adjust the wing mirrors on my MY2011 FL2. The lights on the L and R buttons don't light when selected and the toggle does nothing.

I can't find a fuse related to this in the manual.

The mirror units themselves fold and open properly and the windows also work.

Any ideas?

Update

The only fuse I can find that might do the circuit is FA1 (25 amp) in the luggage compartment fuse box. However, while checking everything again the problem has gone; so I suspect a problem with the switch itself. FL2 2010 (Facelift) TD4 XS
