My lumber motor in drivers seat working but lumber not working. What next? on 2006 Lincoln Town Car

When I press the button under driver seat to operate lumber. I can feel the motor but its not catching so as to make the seat adjustable for lumber use. How can this be repaired?

could be one of the cables fell off the motor or one is broken
