Audi A4 Heater problem

[imported_Bradley]

I have an Auni A4 1.8 97 model. The heater control seems to be broken. The fan speeds and the heat work, however the button at the bottom for switching between keeping the circulating and taking air from outside, seem no to work. I can pushit in and out and when the lights are on the symbol is lit unless i press it


DOes anyone know if this is ok.

Or is is broken

If its fine how do you determine weather the air is coming in from outside or circulating.

Hope people can help.

Korlinski,

I believe the re-circulating button does not work when the air flow dial is pointing in the windscreen position. I think it is because you need fresh air to demist the windscreen.

Does it work when the air flow is pointing towards the feet?
