My power mirror wires were cut in half by the small piece of metal that slides into the door between the two hinges and keeps the door from "over-opening" (hope that's clear). The wires were loose inside the door, and apparently got snipped by that sliding piece.
Also, for my power locks, I had a wire that broke inside the rubber hose section where the wires go from the door to the body (like leebee said). Only the wire itself was broken... the wire insulation was still intact, which made it really hard to find the problem. That problem was intermittent... every once in a while, I would open the passenger door, and when I got it halfway open, I'd hear all the door locks click to the open position. It got really annoying until I took the time to tear it apart and track down the problem.
