Aircon Issue

[silverwqlx]

Hello,
Been a while since I posted anything probably due to the reliable nature of the my 3 door LX. I do have some issues now the first being the aircon doesn't seem to blow cold air...the 10A fuse is good and the button lights up but no refrigeration. I am thinking there is a gas leak or the compressor is gone. Just wondering if anyone has experienced a similar issue and if so what was the fix and the approximate cost ? Note the car has not been driven regularly for 3 months...was just sitting in the garage and warmed up now and then to keep the battery going. Would really appreciate the assistance !
