First step, put a jumper wire across the harness connector to the low
pressure switch at the accumulator (you called it the receiver /dryer) and
see if the compressor engages with the engine running and the A/C turned on.
If it runs then you are probably just low on refrigerant. If it still
doesn't come on then get a good repair manual and follow the trouble
shooting procedures in the book.
