No Power to A/C Compressor

[1stexplorer000]

I have a 1998 Ford Explorer 4.0
I don't have power going to my A/c Pressure Switch.
I have power going to my A/c relay.
I put a new relay in and all my fuses are good.
I was wondering if anyone has any ideas why i am not getting power to my pressure switch behind the compressor???

Is the relay pulling in, (relay coil signal power)?
Is there power at one end of the switched side?
Have you checked continuity of the pressure switches?

What do you mean by the relay pulling in??

energizing/clicking

I havent listened for a clicking, but with the truck running it might be hard for me to hear it!

The compressor won't engage if the gas level is low.
