Sparqui

I just purchased a 1998 Toyota Corolla LE. The moonroof doesn't work, but I knew this before I bought it. The power windows in the door work fine, so I think it isn't a blown fuse since everything I've read indicates that the moonroof and power windows are all driven off the same fuse. I put a volt meter on the switch after pulling it down from the headliner, and none of the 4 wires soldered to it (black, red, yellow, orange) have 12v with the key on. The weather is getting nice here in Issaquah and I would like to have it working. Does anyone have any suggestions for what I can try next?
