Power seat position and operation is controlled through the power seat switch. In most vehicles, when the occupant pushes the switch, the internal contacts are closed and current is allowed to flow to the seat adjustment motor. The seat adjustment motors are bidirectional, with the direction of the motor rotation being determined by which direction the switch is pushed. If the power seat switch is no longer working, it will be obvious because you will not be able to move the seat using the switch. Watch out for signs as well to get it checked before it goes completely out.
