01 A6 The back seat AC / heater vents blow very little air. Any suggestions?

Thanks

 

thats the way it is, its very weak the fan is all the way at the front of the car.

 

I was clearing my car out a few months back and noticed two roundish tissues in the tubing going to the rear AC. I removed them through the same place I thought they may have gotten it.

Basically the area under the hand brake has a gap and somehow it seems that a few tissues ended up rolling down in to the tubing for the rear AC. I got a long screw driver (with tape on the end of it) and got the two/three tissues out. It is certainly better now.

I didn't disassemble anything and it is worth looking into.
