Ford Fiesta '98 - In car heating blowing cold - Nick_R

Having looked on these forums the control valve seems to be the most common problem. Just before I go out and buy a new one... I checked all the pipes going through the valve and they are all hot, which I thought should mean there will be heat going inside the car. Does this mean its not the valve thats at fault?

Could have a blocked matrix or air in system, The valve it normaly the culprit.

The 'heater control valve' is the 'weakest link!' in both the 'Mk4 and Mk5 Fiesta' and the 'Ka' from the same time period.

It might be worth your while, whilst you are replacing the 'HCV valve' and the coolant is drained to renew the 'thermostat at the same time.

Make sure you bleed all of the air out of the system when you are done.
