Thanks for all the suggestions. I was able to get the motor off by 'jogging' the power a little, then it was a matter of following the suggestions in the FAQ section on Sunroofs. I think the only problem was that one screw that holds the motor in, fell out and allowed the motor to loosen a little and the gear slipped on one of the tooth racks and the slides got out of adjustment. Once that was readjusted and the motor put back in, it works fine.
