the power seat module can defintly be causing you issue with the seat movement.
I would check few things before such as visuall inspection of all the wires under the seat, make sure that your switch plate is working, make sure the seat module is getting
power and aslo grounded. your heated seats are another issue altoghter, heat pads under the seat covers can be defective, but again is the switch working sending a command signal, do your basic testing and visual inspections, keep it simple
csheck fuses, ground packs, connectors. good luck
