AB> I've managed without air conditioning in my car since autumn but my wife   
   AB> and I have a baby on the way so I'll need to get it fixed before next   
   AB> summer. I've been told that it's not just lack of Freon. Besides the   
   AB> compressor, what other things are there to go wrong? The car is a 2005   
   AB> Toyota Matrix (Corolla hatchback).   
      
   If it is low on Freon, there is a leak somewhere in the system.  Depends on   
   how big of a leak.     
      
   I would buy a can or two of the A/C charge with leak/fix in it.  Give that a   
   shot and see if you are good.   
      
   There are many parts of the A/C that can leak or be issues.  I had a leak in   
   the accumulator, which isn't more than $100 or so for the part - but getting   
   to it was a good deal of labor.
