Several Jazzy models, some have actual mechanical release, to freewheel-manually push, the chair.
Did they forget to reengage it after they worked on it?

Essentially the power module is sending the same sort of PWM power to the motors if the chair is moving at all, so it seems unlikely that the power module is bad.
The joystick pod sends signals to the power module, and while the signals are different, they travel over the same wires, so it seems unlikely to be cables....
In most (all?) systems, there is a programming function for 'joystick travel' intended to allow adjusting for people that have difficulty moving the stick to it's travel extremes.... If that was not set right, it might cause the described problems. So could a partial failure in the circuitry that senses the joystick position, but I can't think of anything other than programming or a joystick pod issue that would account for the symptoms described....
