I recently went on a trip up to Coffs Harbor from Melbourne and had the aircon working sweet the whole time. I've got back and all the sudden it doesn't work anymore!

I had a look and it has gas in it and when I press the aircon button it starts spinning the aircon rotor on the belt. I also felt the gas pipe leading into the firewall and it is freezing cold.

Anyone had anything similar happen?

What kind of car? my AU is pretty random with it's ac, can be freezing cold etc and after a while normal air. but iam used to it.

Sorry yeah, forgot to mention it is an AU 1999 model..

When I press the aircon button it lights up but there's no difference in temperature between the aircon and having the heater set to cold.

can u hear or feel the clutch engage on the compressor. (when u push the button on the dash the revs drop slightly and then pop back up) or hear a loud click/clunky sound? if not this may mean your aircon needs to be regassed
