Good info - Thanks. My sunroof is the simple older style that only retracts. It isn't capable of raising the rear up for venting. Question about the hand crank. I did try the hand crank. I found the little adapter that fits into the motor assembly(?). Is there some other part that I'm missing? What turns the adapter? Am I supposed to put some pliers on it to get it to crank?

The hand crank is useful when the motor is not working. Your motor works so you won't do much more than the motor did. You should have a device in your tool kit that allows you to turn the drive nut from the motor shaft into the "transmission" which is a clutch device and set of gears to drive a worm and roller that pushes and pulls the cable.
