Just to say guys, if you find your Auto Dimming mirror and orange light hasn't worked since ownership , have a look and see if you have fuse No.27 missing in the fuse panel located behind the pull down (first aid) compartment in the boot, this is what I found in mine and by the looks of it, I would say it was never fitted at the factory for some reason!! and as I mentioned in a previous thread; I wonder how many other Veccys out there with this mirror and light have this fuse missing and hence not working.
