Ok, I still dont understand how the shop can charge you for charging a system that does not work.
Ok. The compressor gets it command from the computer after it sees pressure in the system. Assuming it still has freon, the low pressure switch may be bad. Also, the inside switch on the dash will send a command to the compressor as well.
There are many factors that go into making the compressor work. You will need some help from a shop to diag it for you.
One simple thing you can do is see if there is power to the plug at the compressor. It should be 12 volts and the other side is ground.
