Hello all. My wing mirrors are dead no adjustment or folding. I've checked the fuse it seems to be ok in port 1 a little 5a. I've pulled the switch out on the centre console and I've got 4v going across black and red to brown and black. But I can't find any wiring diagrams or specs to go off, any help will be greatly appreciated. It's a 06 altea 2.0 tdi fr
