My 300's aircon/blower and front and rear wipers are no longer working.. checked the obvious.. ie fuses in footwell and relays under bonnet. but all seem fine.. kind of obvious that theres a poor connection / dry joint somewhere, but where should i start looking...? was hoping that this may be a common problem and someone out there might give me a clue.. zx's seem to be as regular as clock work in respect to things packing up, anyone had this? cheers Gaz, 91 300zx n/a grimsby.
