my 90 td5 2002, just got it, its just had a new head fitted, but the temp needle sits right in the middle of the dial, once its warmed up, but when i put the heater on it blows only cold air, not even a hint of warmth, freeeeeeezing me nuts off, any ideas please
cheers Plod
or the pipes are connected? There should be no reason for it to blow cold air unless it isn't actually getting any hot water in the pipes....
