The A/C in my truck has never worked since the day I bought it, which is over two and a half years ago. Presumably the system is empty (R-12 printed on the compressor). Is there a way I can tell if the compressor is good myself, rather than take it to a shop? If the compressor is blown then to hell with it, maybe someday I'll find a good one at a junkers. In the meantime I'd stick a sunroof in it instead. The clutch works, as I discovered yesterday when I applied +12v to the green wire ontop of the compressor. Any ideas? Thanks.
