Help! No Air...
 

Car is Audi 5000, non turbo, '86.
No matter what position the AC (Auto, Econ or defrost) is put on there is no air comming out from any of the vents. When driving on the highway, there is some air comming out but it is related to the high speed i guess. If the AC is on, the air that comes out is cold. If the car is not moving - no air blowing at all.
2 months ago, air was blowing ONLY from the top vents but then it stopped for no reason.
Please help and suggest what could be the reasons for this problem. Any relays, bad wires, connections, fuses to check and replace....
It is getting cold and in the morning and windows get very foggy when there is no air blowing at all. Hard to drive. How to fix all this?

Thanks in advance.

There should be a law against auto-climate control systems in cars.! Nothing but trouble!
