With both the recline and the lumbar functions not working the two most suspect causes are things they have in common. One is the switch - it could have an internal open circuit in the power or ground circuit or both switches are faulty. Two is connector C340 under the seat is disconnected or partially disconnected. If you also have climate controlled seats, see if that is working as well - if not that system also shares connector C340. If you need to, we can perform some simple electrical diagnostics from the seat switch.
