Ok, changed ignition switch some time ago. During all the pulling i was doing to disconnect one of the looms/plug, i must have 'yanked' a wire somewhere that has shorted out my heated mirrors/rear window demister circuit. my 25A fuse will blow straight away now. had a few good hours under the steering wheel a while ago trying to trace the wiring. sad thing is, my haynes book of lies doesnt quite tally up with the colour coding of my rear demister switch circuit (no surprises there then). anyone got a good wiring circuit diagram and most importantly, a good indication of where the loom may earth out. i have lost both circuits but can here the (a) relay click when pressing the switch even with the 25A fuse gone.
