I don't know that the compressor is or isn't turning, the clutch won't engage. It's not getting a signal to engage, though.

Fuses are good, relay is good. No obvious problems with the control panel. jumping the low switch didn't do anything.

Any tips on checking the other two sensors?

EDIT: Scratch that, I DO know now that the compressor will turn. I jumped 12V to the clutch and it engaged. I'm sort of at a loss why it isn't getting a signal to run, but it's not.
