when i was under the back of the front seats hoovering i did notice a wire going up the back of both seats and a wire going to the base of each seat. ill have to take a look at the rack of switches above the fusebox. ps are all renaults fitted with these's mini fuses. where are you susposed to get them from at a good price :dare you sure it has got them ? the button one that year was normally down the right hand side of the dash i think, the later buttons were on the seat base.
