Volvo Repair: 940 GL-Air Conditioning, leak leaks, voltage supply

Question
I just bought a used 1994 940GL.  I had the air conditioning charged and it worked very well.  Now after a week, the air conditioning is not working, what could be the problem?  

Answer
Hello Joe,

       It would seem to me that you may have a leak...leaks do occur..often.
The many connections and seals expand and contract causing leaks in older A/C systems.
       Perhaps,a fuse failed...or a bad connection related to voltage supply issues.
        Use a test light to trouble shoot this potential electrical problem.

         Again, I think you have leak.
         Have it tested for leaks...see if it holds the vacuum that is used in testing procedures and recharging.
         

            Bye,
