maybe we need more info. it gets hot when you idle down, but gets cold again when you give it gas?
i did a quick word search of the forum for "compressor" and there's lots out on the boards. some guys are shimming, or removing a shim on the a/c compressor, and some guys are just refilling and pressurizing the system. sounds like they are having same problems you are, and fixing it.

HELP!!!! A/C Clutch Turns Off below 1500 RPM's randomly

there's just a couple links.

When the engine is up to temp and you shut the engine off does the fan clutch keep turning? If it does then its bad. Your not moving enough air through the condenser at idle. When your up to speed you force air thru. Replace the fan clutch and you will probably be OK.

you might clean your condensor with some air or water hose at low pressure it made a difference on my 01 v10
