Answers :

When you put on the A/C find out if the compressor is engaging. There are pressure switches for both too little freon or too much freon. If the compressor is not engaging there is a switch on the low pressure side close to the oblong cylinder where you put in the freon. Unplug the switch and put a jumper wire on the wire harness plug. The compressor should engage. If it does you either have too little freon or the low pressure switch is bad.
