Ok All you stilo gurus i need your help. im having a major problem with my climate control. im getting major cold air on the left hand side and very hot on the right side. I assume its probably a distribution motor. the thing is though, which one? because i am confused.

The top left side as your sitting in the car of the climate unit is for the windshield vent of what i figured out. right below it i assume controls the middle and bottom flaps. The outside air is in between the tunnel all the way in the back.

Where is the dualzone flap which i assume is responsible for the major temp diff of each side?

BTW i have already tried doing the relearn procedure but it aint working. (also noted my top windshield motor is not working probably a plastic connector but i havent had time to deal with it yet i dunno if this is affecting the relearn process for the dualzone as well)


Also while trying to figure out which motor is the problem i found this plug coming from behind the ashtray and have no idea where its suppose to be connected. i do see though that it shares the same wire loom as the ash tray light. i looked it up in elearn and found the ashtray light is connector G35 but couldnt figure out what the other connector was i think but not sure its the aerial for the jkeyless entry? (which i dont have btw)

I have the same problem, but not as serious as you. After fixing the defroster flap (as you mention) I'm happy. I can't fix anything outside now, as it's -18°C and I have no garage.

This guy (in the thread above) has made a drawing of the problem area, and I plan to get to it when spring comes. I get max heating with the A/C on 16°C on the driver's side (same as your driver's side).

I never got to fix this last summer.

If you find out anything of relevance, please post it up.

Morten, from the work you've done so far on this, do you think there's anything by way of preventative maintenance that people can do to stop this happening? (e.g. liberal lubrication of the flap actuators, cogs etc).

There is nothing that can be done to prevent it. I am planning to make a simple guide of it, but making time for it right now is quite difficult. The servos are very strong, and I thought earlier that the flap itself would be the one telling the servo to stop. But it is the white link that sends the signal. The servo stops when the link meets an obstacle (metal), and after time it will break. I will use Photoshop to explain on pictures later.

Dealer says it is a dash out job, and I can understand that, since they have to think of their embloyers back and health.

It is possible to fix one link / servo within 45 minutes.

But the main problem with the hot/cold issue is yet to be dealt with. I need at least 30 more °C before I dig up that one.

so let me get this straight the right side of the aircon aseembly there is that white thing that is like a lever and that is what is actually telling the module what position the servos are in?

Any ideas on the connector guys?

ok i reread the post again and again. i guess below the three gears that control the middle and lower vents there is that bosch module that is causing the problem connected to those 3 gears? IM a bit confused though what does the servo flap controlling where air is wanted have to do with lets say the heat/outside air flap?

I didn't find that connector my console. Could it be for an optional extra somewhere?

Hello guys,
What does defroster flap do ? does it allow engine heated air in car interior or puts hot air to front windshield.
Outside air flap what it does? does it let air straight from outside as is no heating or cooling it, or it alows outside air pass by angine and get warm?
To make figs clearer i will say i have now only cold air straight out of outside or i can make it colder by turning conditioner anything else doesn't work ,:slayer:

Yes.... the defrost actuator and flap direct air to the front windscreen to defrost it.

The outside air actuator and flap (also known as recirculator) allows air into the car from outside. The air will be hot or cold, depending on the position of the temperature control(s). The flap can be either open or closed and is controlled by a button on the control panel. On cars fitted with automatic climate control, the flap can also be controlled automatically by a pollution sensor mounted below the windscreen scuttle panel.
