well my ac dont work, it work like 2 years ago. i check the compressor and it seem like it works it makes a clicking noise when i plug it to my battery. wat else should i check for? any help would be appreciated.

 

the system might need to be recharged.

 

so the compressor wont run if you are out of freon?

 

no. it wont blow cold air. i didnt know the compressor wasnt runnning... hit it with a hammer, or replace it.
