Are u talking just the under bonnet end of things or the complete aircon system?.....
If ure just talking under the bonnet side of things ,its easy to do......
Remove aux belt and throw in bin..
Undo pipes on rear of aircon compressor
Unplug wiring on compressor.
Remove 4 bolts holding compressor and remove...
Replace aux belt with one from a vx220
Pipework i just cut out what i could see,as it wasnt goin back on..
Before doin any of the above get the system emptyed by a garage as you will get hung if you get caught letting it out into atmosphere..
I wudnt personally remove any of the aircon from inside the car as you will have to replace the complete heaterbox assembly with one from a non aircon car..
