There's ANOTHER secret module that's missing - the seat MEMORY module. Mounted under the driver's seat, it controls both sides power seat position, and the heaters. It gets data link messages from the DDM when you control the heaters.
If you have a tech tool, you must have access to the schematics. The memory seat system is a lot more complex than the manual power seats.
