Thanks guys, there is a rather large relay 8 pin under the bonnet on the firewall 50A/20A 8 pin which may be associated with the issue, not sure of it's function but i just know unplugging it doesn't currently break anything that i can find. I think i've found one locally so will replace and try. A lot of the wiring diagrams out there seem mislabelled, aussiblues above doesn't match my fuse ratings etc while it IS tagged as Ka Mk1 on the site. Hoping this gets me over the hump. I never run the AC normally, just had one of the kids in the car on a mid-30's day so weakened. There went half the engines 44kw ;)
