hello to all forum members.
i am new, actually this is my 1st post

Anyway, my problem is:

My car is 1.2 stilo 3D with a dual-zone A/C-heating unit.

On morning, like any other mornings, i press the button to start spreading the heat. The weird think was that whatever button is pressed (top, front, low, or any combination of those) i could get some heat (or some cold) only from the top part. No kind of air is getting out from bottom or front. it doesn't matter which button is pressed. The air is always coming from the top.

Anybody knows anything about it ???

I want to say sorry for my English. (not my native language).

Thank you in advance
Marios

I had the same problem. There is a switch type thing behind the dash. Have a search for threads started by me.

first of all try this:-

CLIMATE CONTROL SELF-LEARNING PROCEDURE

The AUTO and MONO buttons must be pressed simultaneously within 40 seconds of the ignition being turned to the ON position in order to active this procedure.

A few seconds later a figure will appear on the display (in place of the driver's side set temperature) which will count down to indicate the time remaining before the start of the procedure. At the same time (i.e. whilst the count down is taking place) the previous self-learning status is signalled on the passenger temperature setting:

'1' flashes if the previous self-learning procedure failed.
'0' indicates that the previous self-learning procedure was successful.

This procedure is not carried out if at least one of the above mentioned buttons is released whilst the figure on the left hand side is not zero (this is designed to check the outcome of the previous self-learning procedure).

Exiting the procedure zeroes the 40 second counting period from when the ignition is switched ON, to allow the procedure to be repeated without having to switch the ignition OFF.

Each time a new control unit is fitted, the flap actuator learning test must be carried out using the diagnostic equipment and the unit must be personalized through programming.

if still no joy try this:-

if those 2 dont work then i can help no further!

Thanks Richy,

Did what you said,turned the ignition to on, pressed the Auto and Mono at the same time, and bingo. it seemed to have reset itself,cold coming from both sides now.

Many Thanks

Tom
