Locks are independent of seats. The PDL actuator is a 2 way Solenoid so reversing the Hot is what unlocks or locks the door.
Only one direction usually means a switch issue if its both doing same thing.
Newer cars use a stepper motor and a worm gear thats much lighter, more reliable and uses way less current.
Easy to upgrade and not seen.
