Most often, when you have a good seat switch and good seat motors but can not get them to cooperate, you have fatigue in the wire harness that flexes between the door and the body of the car.

As a test, switch on power at the ignition. Operate the seat switch at the same time open the door. Or sway the door back and forth as you are still operating the switch and see if the seat comes alive...even for a second.

One or more severed wires in the harness is the cause.
