You said you checked most of the fuses. You should check the specific fuse for that seat, which should be two separate fuses for Heat/position.
If the fuses are good, then you could check continuity of the circuit by removing the fuses and inserting a test light into the terminals and having someone operate the controls. If the light comes on, the circuit is fine. If not, you'll have to trace the problem.
If the circuit is good, then you're looking at a failed motor/heater.
