So is there dual drive motors? When your on the seat and activate the seat switch, is there a display message for brake pedal to be pressed, which type of direction control? Shift lever or is it on the accelerator pedal for monotrol? Do you have access to the service menus?
Typical AC motors in any of these situations are not a rebuild unless it's a specific code for the encoder.
Do you hear the brakes activate or release?
