On our '55, I found that cleaning the worm drives enabled the motors to work properly. There was a tremendous accumulation of dust bunnies and under-seat crud on the worm drives even though they were enclosed in clear plastic tubes. The motors are controlled by relays on each motor and powered through a circuit breaker inside the driver's side kick panel. I disconnected the motors from the drive screws and determined both motors worked fine in both directions. The problem was the crud was jamming the drives. Cleaning and light lubing the seat linkage points would also make sense. Review the service instructions in the service manual for helpful hints. Good luck.
