10-4 on that.
Sounds like you got to talk to a good parts man.

If you need help on it we need more info.
Dual zone or single zone or auto ac controls?
Are the controls working right like vent and floor and defrost switch and fan all speeds and tempt change from cold to hot?
Any check engine or flashing lights on?
What engine?

First thing you need to do is check all fuses in all fuse blocks.
There is several different fuses foe clutch and HAVC controls.

If the only problem is compressor clutch will not turn on.
Unplug compressor.
And check for 12 volt power to clutch on one side black wire should have 12 volts key on.

If 12 volts on one side black wire.
Then go to the other wire Dark /green,
Jumper in a ground wire on it.
Plug clutch back up and turn key on and ground dark green wire,
The clutch should kick on when you ground the ground side dark green.
If so leave it grounded and start engine and see if compressor runs ac lines and ac gets cold.
That is only a test so do not leave compressor jumped very long.

A bad AC or plugged system the pressure can go to 500 lbs or more so be careful out there.

Post back if clutch kicks in and ac gets cold.
