Constant Hot Air In Fiesta '05 1.4

[danjama]

Hi guys, it seems the heating is stuck on inside my Fiesta - hot air blows through all vents regardless of where I set the dials. I did a bit of research but could only find info on this problem on the previous mark of Fiesta - the common issue was with the heater control valve. However, I can't see a HCV in the place I would expect on my Fiesta (two inlet pipes near bulkhead). Can anyone shed any light on what may be at fault here? Is it the HCV and where is it located? Or could it be something else?

Very grateful for any advice, want to get this fixed before another heatwave arrives.

(Also of note, the faster i'm going, the hotter it gets).

Surely someone can help with this? ;)
