Also, if I put 12v to the terminals on the motor itself, it just makes a buzzing noise, doesn't blow. Can someone guide me to what I should do next? I suspect the pump is shot so I'm going to replace it, but not having any voltage appear on those wires concerns me a little. I haven't taken out the relay yet to check it, figured if the pump wasn't working, no further troubleshooting until I resolved that. Thanks!
If the motor has broken and does not turn then it is possible that the fuse for it that is on the RCM has blown. It could have blown because of the power called for when it would not operate. Also look at the contacts on the relays to see if any are burnt, if they are burnt they should be replaced.
While you are at it check the solder joints shown in the RCM repair thread.
