Compressor Relay doesn't fire???

[Invictus3593]

After an accidental +12v-to-frame short, our Compressor Relay suddenly will not fire. We put the robot into Test mode and tried manually starting the relay, but we don't even get the green relay light on the sidecar (keep in mind none of the robot code changed). We have changed the sidecar (confirmed fried), crio (smells fried), 9403 card, relay, anything that is inbetween the computer and the sidecar that could interrupt the code from reaching the SideCar but still no relay. The pressure switch isn't stopping it, that works fine.

The odd thing about the whole situation is that all of our motors, solenoids and everything EXCEPT that relay works. We don't have any other relays, we tried different relay channels and even bypassing the router and going straight tether-to-crio. Still nothing.

Any ideas on what our problem could be?
