AC pump wont engage

[MXJUNKY774]

My ac pump wont engage with the switch on the dash. The light comes on but the clutch wont engage. I ran jumper wires from the battery and it kicks on. The fan only works on high. Is it the switch? I don't know. I tried a working relay out of my F250 and it didn't change anything. Anyone???
