Hi All, Focus 2002 1.6 Ghia saloon Petrol. The temperature control knob was stuck on cold, I physically could not move it across to hot. I thought it might be a broken/seized/kinked cable but when I took the cable off at the knob and at the drivers feet I could see that it works fine. With the cable removed (red arrow below) I can see/feel that the little black knob it attaches to (green arrow below) is stuck and will not move. Does anyone know what I can try next. I've read elsewhere that the "Blend door" could be stuck. Anyone know where this is or how I can get at it to perhaps manually move it to warm? (It's getting pretty cold out now!). Should I try and remove the white piece in the picture below? Any help would be greatly appreciated.
