TO TEST JUST THE AC PUMP/CLUTCH.
Take a piece of wire and connect one end to the +(plus) of the battery and the other end to the plug for the a/c compressor ( there's only one wire that goes to the compressor). Your basically jumping the compressor to see if it comes on. If it does place your can of r134 on there and charge it up. It should be fine after that.
1. If you jump the compressor and still does not turn on - its dead.
2. if you jumped 12v to the clutch and it came on and while on. you connected the r134 and charged it then reconnected the plug to the compressor and the ac still does not come on that means your hi/lo pressure switch on your receiver/dryer is bad.

TO TEST THE ELECTRICAL SYSTEM.
or VERY short periods of time you can check the compressor by bypassing this pressure switch (jump the 2 pins with a wire) and the compressor should kick on and run normally... dont do this for more than a minute or so though. cross the 2 prongs and the compressor thinks theres enough freon in the system and runs.

sorry its 9pm here in NJ, so my picture is dark
