Hi people,
The mrs got in the car this morning and pressed the defrost function on the climate unit.......blower powered up, but it didn't direct the air to the screen! All other functions work fine except this!!
Car is an A4 1.9TDi SE Avant 2003 with climate control
All help or advice greatly appreciated!

Ive had this 3 times with mine in the last 6 months,
Everybody said its definitely the green flap motor behind the glove box, Each time on mine it had been the climatronic dash unit at fault, but only ever replaced with another second hand one,
A good diagnostic code read is the first step really[emoji106]

Cheers fil1973, great info as to the location and possible cause! Do you happen to know how i access this motor/problem? I've got VAG-COM and will get it on there today or tomorrow.
Cheers

I would certainly start with the flap motor as it is by far the most common cause. Whip the glovebox out and the motor has a green arm attached which controls the flap. Operate the controls to go to defrost and back and see if the arm moves, if it doesn't (or only moves slightly) that is almost certainly your problem. Either try stripping and lubricating the mechanism inside the motor unit as well as cleaning the contacts (fiddly but possible and many people report success) or buy a new unit (about £100 last time I got one).

Nice one guys, I'll have a look over the weekend and report back! I also recall a previous 'flap fault code' on a previous diagnostic but it cleared and continued to work......watch this space!

All sorted, it was the flap motor. I got one from a breakers car with 60k less mileage for less than a tenner and took less than 30mins to fix! I love this forum!!!

Great .I sorted mine by regreasing it about 2yrs ago.The original grease hardens in time and blocks the cogs.I think its a good idea to use the flap regularly even in summer to keep it from gumming up cos it seems to be such a common fault and its a pain to lose the demister just when you need it most
