    today i finally got my ass into gear and patched in the heater feed for my electric mirrors. Was feeling chuffed at finally doing it, however, going out for a drive before and i realised i now have no dash lights, nor heater control lights.

    I changed the switch, checked the fuse, checked the dimmer, the side and headlights all come on, but no instrument lights. I doubt very much all bulbs (as the heater control light isnt working either) have blown, can anyone shed any light (no pun intended :) ) on the matter?

    I did have the fuse box down while i found the white/green rear screen demist wire to scotch into for the mirrors, but other than this i didnt do anything else. Im finding it a bit strange! ive checked all relays and connections are all in ok on the fuse box, does anyone know of any specific areas on the fuse box i should pay attention too?

    cheers all!

    Well I had to ask :lol: I'd say you might have disturbed a plug on the back of the fusebox somewhere, have a feel round the back of it and make sure they're all pressed in fully.

    Check the Grey/Blue wire from the Back of the switch, this might have a break someware or chaffed/ Got trapped.


    This is your Dashillumination wire,


    trace it behind the dash and see whare it goes and what has happened to it.


    let me know

    It depends what year your MK2 is, the pre90 ones are different, I put the wiring for the pre90 fusebox a few posts down in that FAQ :)
