C5 Dual Zone Climate

[Guest Visa10E]

Hi there, the split zone climate on my 02 C5 2.2 HDi Exclusive seems to be only half working - ie when both sides are set to 22 the left centre vent is blowing out hot air and the right cold air, if I whack it up to full blast it gets slightly better but still not equal. Is this merely a 'characteristic' of the system, ie its designed to be used with the air con on for example or is this a common fault?

Any clues? Now the passenger side only blows hot air out even if I put it on 16 with air con on!

There are probably little motors that move the various flaps to give the air distribution/temperature so chances are one of these is not working.

Unfortunately you have encountered a fairly common problem with the C5 heating /ventilation system. I seems the flaps that redirect the airflow have gear teeth on them and being made of plastic these wear out. If you have a look through this forum it's been talked about a few times before. I can't remember the solution but being a C5 it will undoubtedly be complicated and expensive. Good luck. Malcolm

Pretty sure there was mention of a modification kit from one of the resident Citroen techies.

The problem seems to have gone away for now, and only seems to rear its ugly head ocassionally, ive found that turning the ignition off and on again can sometimes cure it, but for now I'm just going to live with it as I'd rather spend the money on cambelt etc I would like to know what the previous guy meant with a 'modification kit'

Had the same problem on my 2001 C5 V6. The servo motor needed to be replaced, otherwise the control for the hot/cold air will be next to non-existant after a while. Repair ran £160, covered by warranty (used car warranty is three months in Sweden where I am).

In my experience the issue was not the motor itself but the fact it was spinning inside the flaps   https://drive.google.com/folderview?id=0B9Ls81E7uVtLY3JUNjlZdndyb28&usp=sharing
