ok so i dont know whats happened but today i tried fitting a solenoid to my boot but via my rear wiper switch. (so push rear wiper, boot pops e.t.c) and took me ages to set up. Finally set it right and it worked once. Now no power whatsoever and have realised that the windscreen washer switch now does not work aswell. The wiper's work but no the washer or rear wiper? Tried the fuses but they seem fine (btw how do i tell if its a fuse) and replaced in case. Just seem brainless as to what it could be? any ideas guys??
