Saab: saab 900 ac, saab 900, air conditioner

Question
i know you said 80's 900s, but i have a 96 900 and all of a sudden the air conditioner stopped blowing cold air.  now it's like just the vent is on or something.  maybe you can give me some tips.  thank you, either way.

Answer
I would check the following, please keep in mind that I don't know air conditioners real well:
-AC fuse
-Check that the compressor clicks when the vehicle is running and you turn on the air conditioner.
-Have a shop check the high and low side pressure
