Heat system is not working correct?

[Quattro Ayes]

Hi all. I can't get my heater to blow air up on the windows. It is only letting air down to the feet. And I have tried to push all the buttons on the heater. Anybody have had the same problem? Cheers Anders

Anders, you've not told us enough to know which unit you've got but assuming you've got the climate control only fitted as OE to LHD cars then it looks as though the flap motor which directs the air to your feet or the screen has either broken or a wire to it has broken.

You can find the wiring diagrams on S2central.net and there was a post not too long back on a similar topic which contained information in testing out the flap motors.

If you disconnect the loom from the climate control unit to the motor, you can drive the motor on its own using a 9v battery wired to pins 1 & 2 on the motor. Just reverse the battery to make the motor and flap go the other way.

Yes it is the climate control in my s2 avant. Okay I will try that. thanks

if you have the klimatronic, you can check for faults on it.

[Quattro Ayes]

Okay. With vagcom?

[Skull]

no, with the klimatronic

hold the recirculation button pressed, and pres the up arrow.

now it should write 1c

release all buttons. press recirculation button again.

write here what numbers you get on the display.

[Quattro Ayes]

Okay. It writes 11,7-13,5-15,5-08,7 It comes in that order.

A lot of faults

11,7 Central Flap, sporadic block

13,5 Footwell/Defroster Flap, static block / Motor is cycled; software attempts to eliminate block

15,5 Air Flow Flap, static block / Motor is cycled; software attempts to eliminate block

08,7 Temperature Regulator Flap, sporadic block

that is weird. it shows that 2 flaps are blocked permanently, 2 are blocked sometimes. i think what follows it to remove the dashboard, and see what is the problem in the box. either something is broken (levers) or something is blocking the flaps. very strange.

How do I get in there where it happens the easiest way?

[Skull]

There is no easy way. You need to remove the dashboard, and remove the whole klimabox from the car

here is a guide how to remove the dashboard and klimabox.

Okay. Thank you skull. I will get to it one day and see whats blocking the damn thing.

[Error404]

I bet its the foam padding on the flaps is coming off and making a mess everywhere

[Quattro Ayes]

Maybe. But the only solution is getting the dashboard out and see whats in it. Nobody who knows a trick which could help? How long does it take to pull it out?

[Skull]

one day alltogether. it is very time consuming, specially if you are going to do this for the first time...

[Quattro Ayes]

I am.
