Air con matrix removal

Hi All,

Anybody had any experience in getting to the air con matrix behind the dash. My air-con stopped working & got it re-charged, it lasted a couple of days & all the while I could smell oily gas type smells coming through the air vents. I therefore believe it's the matrix behind the dash that has gone & want to get to it to have a look. I can see how to get to the hot radaiator but the air con side looks like a black wall!

This is on a 59 plate 1.4HDi

Any help appreciated!

Hi zebedee2001. I have not had to replace one before, thankfully. The heater/cooling evaporator housing on the C3, as for many cars, is a very long and complicated job. Stripping out the dashboard to get to the guts of it.

I think you will find the evaporator unit for the Air Con being accessed after removing part 7 in the diagram. This is underneath the whole unit, so I would imagine you need to remove the whole thing to get to it.

Follow the arrows and this is where I think it will be
6 is the electric heating element

No.7 but from the drivers foot well view.


and 7 and 6 from the passenger side

The video shows a LHD C2 heater matrix removal, but also shows the air con evaporator in place when the heater matrix was removed. It is the same setup in a C3 2002-2009 RHD.
