      well it wont blow out cold air. usually when i would turn it on you could hear the engine rev as it takes the load of the compressor and now it doesnt do that. and isnt the radiator fan supposed to kick on whenever you have the ac on? well mine doesnt.

        the radiator fan only kicks in when the cooling system of the engine gets to a certant temperatur and when the a/c system lines get at a certant temperature and usualy only kick in when you are rest, i.e. sitting at a red light or stuck in traffic.

          so do yall think that its my compressor or just low on freon? i havent got the money to get the gauge so as soon as i do where do i hook it up to? the port on the accumulator?

            You can just get an R134A refill kit at Wal Mart or someplace like that that includes a gauge and a can of freon. It's not too expensive. I think that's where I got mine. And yes, you hook it up to the accumulator (the big silver cylinder). That's the low-pressure side. Never hook anything up to the high-pressure side.

                there is a lot that goes into teh AC system. first comfirm that the compressor is not coming on at all or if it going on and off rapidly.


                if it's not at all then the next step will be to see if you have the correct amount of pressure in the system. we can go from there
