Well the compressor on the fan belt makes a whining noise. I always thot it was just the way the Rangers sounded until my buddy got one and it dosent make that noise. Im not sure on what to put for description other that it hums and makes a whining noise :P

And it only makes this noise while the compressor clutch is engaged? Or all the time?

Then it isn't the AC compressor, since the compressor isn't running the whole time the truck is running. It is probably a pulley (either the AC or some other one).

I don't know. Pulleys come as a whole thing. But if the noise happens all the time, it could be any number of things.
