air. con.
 

I have a VW Passat 3BG from 2001 1.9 TDI 130 horsepower.
It could not keep air pressure up, so I changed the AC. compressor, and got filled on freon ..
Now run the system itself so fine, and it is checked.
BUT the cold air does not come into the cabin, there are some who have a suggestion for what it might be? it could well blow cold air into before I switched the compressor ..
I have a VAG computer but can not communicate with my control unit for comfort system, because there has been water in the bottom at some point.
