What's missing in the pics?

Hi.
My first post and my first Citroen
It is a 52 plate C3 1.4HDi (92PS) Exclusive with digital climate control.
This seems to work... but there appears to be something missing from the heater housing, which lets air blast into the passenger footwell. I found a picture on Google that shows what I think should be there and a shot of mine for comparison. There is a bundle of wires tucked away behind with a four pin connector that looks a lot like the one on the photo. I assume whatever switch/sensor should be there broke a and a previous keeper never bothered to replace it.
My question - what's missing and what does it do?

Any help appreciated. I tried the local dealer by phone, but it was difficult to explain and they wanted to know what part I wanted - I just don't know!

Its this:

and this is what it looks like when fitted:

The cabin supplementary heater for cars with diesel engines

Have a look at citroen-c3-questions/diesel-heater-exch ... t1320.html where the pictures above were originally posted.

And have a look at this ebay link if you wanted one cheaper than the dealer price Heater element C3

Some more pictures of the cabin heater on a Citroen C3 after removing from the car.

Excellent thanks very much

I can't confirm which part I had due to its absence and I see two part numbers listed, 6436A9 from the post you mentioned and 664447a on Ebay?
Any idea on the difference? I'll message the sellers aswell.

Thanks again

Btw local dealer wants £153 for it, but won't give away the part number

6436 A9 is the Citroen part number and 664447a is the Valeo part number for the same part. The ebay link is the right part

Part ordered for £20 incl shipping (new allegedly).
Most grateful!
