My AC in my 94 LS went out in the middle of last summer. So I thought the refrigerant ran out, so I bought a can of R134a refrigerant and recharged the system, this worked for like 2 weeks then it went out again. So I just kept charging it with a can of refrigerant every couple of weeks.

After a whole winter now, it's getting hot again. (YES, it does get hot in Michigan too.) I charged my AC again with a can of R134a, but this time, it only lasted like 3 days.

So do I have a leak in the system? How can I tell and get it fixed? is it expensive to get it fixed?
OR do I have something broken? Thanks in Advance

you probably need a new AC compressor....they usually ten to fail after awhile on Legends......im working on getting one for my coupe right now. at the dealership the ac compressor costs about 700. im trying to get used one from a junk yard for like 150.

First step is to take it to a facility having an A/C charging station and have the system placed under vacuum. This will determine if there is a leak. Then a partial charge with dye to determine where leak exists.

there is no doubt you have a leak, you just need to know where and what is leaking. Most modern facilities can test using a sniffer rather than the older dye technique (it is hard to see the dye with the congestion under the hood and the sniffer will detect very small leaks). I doubt it is your compressor. Most likely either a bad hose fitting, seal or condensor. Be prepared though....a new condensor is about $600 installed (you will need to replace the drier as well if the system is taken apart). Sometimes if you replace the leaking part and get the system fully charged, the next weak spot in the system will go out.

I went through that whole weak link breaking thing on another car I owned and it ended up costing a lot - it would have been better to bail early but you don't know that until too late. I just had my AC fixed on my coupe and it ended up being an electrical relay - it would just blow warm air. There is a great troubleshooting section in the service manual that has you fix the most likely suspects, but in your case there is no mystery.
