There is a fuse and relay for the compressor. Most times when it doesn't come on and is full of freon, it is the high pressure switch that is bad.

check the wire from the ac clutch back and look for a dead short to earth . look for pinched wire. Wire worn by drive belt etc. Any indication of where a live wire is touching earth.

Check fuses and relays. On relay just switch with one you no works.

In a fuse box near the battery.

If you do not have enough refrigerant in the system. The low pressure switch will prevent the compressor from engaging to avoid damage.

Check your pressure.

I don't recommend this, but you may need to jump your low pressure switch to get the compressor going to add more refrigerant to the system. But if your low on charge, it may be "best to take it to a shop to have them fill the system".

check for bad fuse under hood. also check for ac relay issue. also under hood . you will find a power dis. center under the hood. (just like a fuse panel)the system does use pressure switches, but check the fuse and relay first. if you have power and ground at the compressor and it does not engage, then the ac clutch is bad. you can check that at the two wires at ac compressor w/ a test light.

The AC relay is located in the under hood fuse box. The cover should have a legend for location. Its one of the bigger black ones. You can rotate it with the horn or ABS one to see if its the problem. You may have a small fuse also in that box for it. If this doesn't solve the problem then you either have a leak or a computer problem. What a shop will do is try with a bidirectional data scanner turn the AC on. If they can't get it to turn on with a scanner then you most likely have a failed PCM if they verified you do not have low pressure or a relay or wiring or switch issue.

There may be a fault in the control group in the dash--there is a resistor that controls motor speed as well as the speed switch.
