Sounds like the memory seat module has gone berserk. Not moving rear or forward could be due to a bad horizontal seat sensor, but the way the switchs are operating one would think it is the module.

There is a memory seat calibration for new modules. So, I would unplug power and let it sit for a few minutes, plug back in and try the calibration procedure. (Not sure if unplugging with do anything, but it might be worth a try.)

Memory Seat Calibration
The memory seat module uses position sensor inputs to establish soft stop locations for the adjuster motors several millimeters ahead of the physical limits of the adjuster assembly. After replacing a memory seat module or adjuster components, it may be necessary to reset the adjuster motor soft stop locations. When the repair procedure has been completed, operate the seat adjuster switch in every direction until the seat adjuster reaches its mechanical hard stop by repeatedly pressing and releasing the switch as necessary.
