Ford Fiesta heater always cold

Hi there
On your model there should be a control valve for the heater under the bonnet slightly to the left just below the windscreen, you can see the heater hoses going into it, this will be faulty, a common problem, assuming of course all your other controls internally are functioning ok. cheers

I agea with Rizzo,not long done this job on my daughters Fiesta,heater control valve under the bonnet ,as Rizzo said two pipes going from the front two going out at the back of the heater control valve ,very cheap part and easy job to do,you will loose a little water doing it,unclip the hoses front and back ,it fits on the bulk head between your wipers,took me 15 min, hoses need a bit of persuasion to get off,then you are flying,good luck.ps look in your book ,if no book have a look on ebay for the heater control valve for you car so you know what to look for,
