Apologies if this has been covered before: I couldn't find anything, probably because I'm not sure of the correct name of this component.

One of the pictured items, part number 4M5H-19236-AB, which controls the HVAC blend flaps in my car, a 2010 Focus 1.8 mark 2.5. The one in my car doesn't do anything when I turn the heater control for screen/screen and feet etc. Fortunately, it seems to be stuck halfway between screen and feet! The larger green plastic part is broken about 3/4 of the way down.

Removing the radio, you can see where it connects to the blend control, but then it disappears towards the passenger side to a point where I *just* about cant see what it connects to.

Zero Alpha has a car the same as mine, so I took hers apart too (I got into trouble for that. Think "all picture and no sound", you won't be far off :D) It seems to be the same, although the component in her car moves and does what's expected.

I have the Ford Workshop Information System, but find it a bit counterintuitive to navigate, and couldn't find anything.

Anyone know where I could find the instructions on how to fit this thing? I know you get instructions with things like mudflaps from Ford, but I doubt something like this would be the same, as it's not exactly a 'consumer-fit' item.

Cheers in advance.

The cable simply pulls out of the back of the dial and the flap control mechanism in the footwell.
I replaced one on my old mk2 Focus a few years back.
It's easier to do the dial end first then the footwell end as the flap end plastic part is longer and can snap if trying to flex it into position without the flap end being free to move around.
Make sure you don't spin any dials after disconnecting the cable or you have a faff realigning them.
You may need to disconnect fan speed control wire and temperature control wire in order to pull the aircon control panel up and off for better access for cable alignment.

Thanks Stoney, I didn't realise the other end was on the footwell: it looked to me like it went up into the top area of the dash.

Great stuff! Cheers.

Tbh, It was such a long time ago that I did this job I can't truly recall where the other end leads to.

Best idea is to just trace it back before you remove it and if possible take photos of it's link point to the flap actuator so you have a good reference point to aim for.

Problem solved!

The photo I posted in the OP of the component is indeed the totality of the replacement part: I was barking up the wrong tree looking for the other end of it on the heater box. The yellow arrow shows the end of the component. The red arrow indicates where there is some kind of cable with a toothed socket on the end of it. It's not visible as you can see that the grey plastic section is in front of it.

I was actually trying to pull that part OUT, in order to get a look at it. However, I noticed that there was some kind of spring loading on it, so I let it go and it snapped home, not fully, but more than before. Whacked on the blower and turned the knob for the blend: working! But as Eric Morecambe would have said "Not necessarily in the right order"
 

1. I moved the blend control knob, ignoring it's position until it was clearly outputting to screen only
2.  Pulled on the joint (yellow arrow) until the rod was disengaged
3. Placed the blend control knob at 12 o'clock (screen only)
4. Let go of the joint. It didn't snap fully home straight away, so I pulled on it a few times and it popped in.

All working now. Dunno how it got pulled out, mind.

Hopefully this will help someone else in the future.
