I have a B7 2006 A4 saloon with dual zone climate
the air started to blow cool on drivers side whilst warm/hot on pass side when the temp was set to HI or warm. I looked on this site at other threads and thought it could be the motor that controls the flap behind dash, I removed the panel under the column and saw a yellow three part arm above the two heater pipes, this was hanging loose and by manually moving this i was able to make the air blow warm. there is a box the size of a matchbox with a wiring block going in to it fixed by 2 bolts, I assumed that this is the motor and the arm should be connected to this, the end of the yellow arm looks as though it has sheared at the point where it fixes, it doesnt look as if the arm can be repaired, does a new motor come with a new arm or part of, it is arkward to get to and fixed on with 6mm bolts
any light shed on this would be welcomed.
thanks
