Fiesta Heaters Always Blowing Hot!


Recommended Posts

ok well i expect a lot of you know exactly what im talking about, as ive been told its a common problem! basically even when the heaters are on cold it still blows out hot, and it can get really un-bearable. ive heard that its something to do with the heater valve? if it is, is it something i can do myself? unless any of you might know another problem, im open to any diagnosis.

It's probably your Heater Control Valve (or HCV for short)

Go to Ford to get one as the eBay / pattern parts are of dubious quality. Also getting it from Ford, should it fail within 12 months, (not uncommon) they should replace it free of charge (well my one does :P )

Ford's latest HCV is Finis Code 1714716 (7N21 18495 AC)

Probably about £40 (depeding on our dealer) and I can do one in about 10 mins on a Puma (same as the fiesta) 4 pipes to take off / reconnect and an electrical connector.
