Just when everything was working well...

My front power passenger seat in my '03 PAU is stuck in the forward, or upright, position. I moved it forward to get a large package in the back seat and now when I move the button to tilt it back, I just hear and feel a "clunk" underneath the seat, but the seat doesn't move.

Does the tilt motor use a cable, or a set of gears to adjust the seat?

All other movements of the seat work fine.
