You could try to see if the relay works

Initializing : Relay compRelay;
compRelay(COMPRESSOR_RELAY_CHANNEL),

and then set it to turn on if you hit a button

if (stick.GetRawButton(PICK_A_BUTTON))
compRelay.Set(Relay::kOn);
else
compRelay.Set(Relay::kOff);

If this works (side car relay light turns on) on the hardware side, but it doesn't turn on, check your hardware. Also, make sure you connected the relay to a relay port, not a pwm port

Once this works, and you know if the compressor works, and you can debug the auto cutoff switch.

P.S. if you're running a 2013 crio image with 2014 wpi, it won't work, we tried.
