ok the blower works but no heat, what would be the first most common thing to check, bearing in mind i checked the hose to the heater matrix thing, they are getting hot, just no hot air, would it be an easy fix?

oh one more thing, the radiator fan only comes on when i disconnect it from the thermostat switch, and off when plugged in, it doesn't ever seem to come on when plugged in, would that be the switch bolloxed or summin else, if so where would i get the stat switch?

cheers
