Hello to everybody on this forum. Before anybody slates me for repeating this thread, i have looked through the previous threads using the search facility and honestly i am none the wiser. Firstly my car, a 2.3 petrol y reg 67000 miles runs okay on a run and doesn't overheat in traffic so i assume that the water pump is working fine. The blower switch is working on all speeds but there is no heat through the vents at all. The air conditioning switch, recirculating air switch and the auxhillary heating switches are not doing anything. Obviously, the rear heater switch is not working. Is it possible that a relay has caused this problem, and if so where are they located and how do i test it. I thought that a flap might be stuck open or closed due to the electrics? Please can anybody help me with this problem as going on holiday soon to a cold Blackpool. Also, the rear wiper works but in jerks, stop start etc. Any advice greatly appreciated. Dave
