I have a 2004 S-Type Sport diesel suto 2.8 and no problems for the 12 months I've had it till now -- the heater , when switched on, just blow warm-hot air all the time, and the AC doesnt work (though the lights come on), whatever temperature set. My local garage doesnt think it's the AC needing a regas -- probably some electrical fault -- does anyone know what it might be?Many thanks -- Alan
