The circuit breaker when removed should be in the closed position and you can do a simple continuity test to confirm that it flows current. If the circuit breaker is open then it will have to be replaced and the system further tested.
If the circuit breaker continues to overheat and open the circuit your attention should be turned to inspecting the seat tracks for debris or binding. Even if a soda is spilled in the vehicle it is possible for the track to become sticky enough to overheat the power seat motor.
On older vehicles in some cases corrosion can build up on power seat switch contacts. On some models these switches can be disassembled and the contacts cleaned with either electrical cleaner or even a small piece of sandpaper.
