Heater Stuck On Cold

4 posts in this topic

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.

Remove the radio and surround (make sure you have the code first) and access the heater control from behind.

Look for a cable on a large black camwheel.

I suspect it is kinked or detached from the wheel somehow.

The cable should be hooked onto the camwheel at point A and a tensioning block for the cable sleeve should be clipped into point B.

A useful guide to removing the radio (ignore the half about fitting an upgraded radio).

This is what you're looking for-

Yeah always store radio code as a contact on your phone.
