Question about Cars & Trucks
There is a clutch which make the compressor engaged. If the clutch is old it sometimes slips. Loosen the (normally) three screws in the front of the compressor. Then put three (or more)
plastic tabs under the screw heads before tighten them again. You find the plastic tabs as closure of your bread plastic bags. The thickness is perfect to make the aircon run again!

There are a few different possibilities for a vehicle doing this. A low refridgerant level can, or a temp control on the dash is not operating properly.

May be your heater/AC control unit in the dash if you have already replaced the mixing valve for the heater.Must be a problem. I just responded to the same issue for a 2004 Focus.

Not sure how you know if the freon is full without the unit running. There are a number of switches which can keep your A/C from coming on. There is a low pressure switch which is usually located on the larger line and sometimes located on a silver cannister (called an accumulator) which is the low side of a compressor circuit. There is also a high pressure cutout which is usually located on the back of the compressor unit. Both of these switches can be jumpered out to see if they are the reason for the compressor not working. You remove the two wire connector to either switch and place a small jumper wire between the two wires on the connector block. The other reason my be a low idle cutout switch and this will also usually be located near on on the compressor. You can also test it the same way as the other switches. If it is the low pressure switch then of course you will need to add freon which you can purchase from any auto parts store. They usually come with instructions and all the equipment needed to add in freon. If it is high pressure, then some of the freon should be recovered from the system by a technician. If is the low idle cutout then you will have to take it to a mechanic to understand why it is idling so low. Hope this helps.
