Yeah I go through an AC compressor every year because of mud and water. Need a new one at the moment actually. I have gotten mine in the past from niss4x4 in melbourne, they are around 200 bucks sent over from memory. Do you know what type you need as I have one at home from a different model D22 than mine. I can take a pic and post it up on here if you are interested. I went out last weekend to the byford hills to ride motos with a bunch of mates, we ended up getting busted by the water corp as apparently its a water catchment area. Suck balls that there is becoming less and less places for us to go and have a bit of fun.
