I've had this problem several times. There was a wire going into the bottom of the relay box in left side under seat in engine compartment that had backed out. The connector pin kept backing out. I cannot remember what number it was but you should be able to find the seat switch relay and figure out where the connectors are.
Hello James,
I think it's a wiring problem, we had the same problem in the past. The wiring (several wires that are connected to each other) that runs to the OPSS had come loose, you can only see this if you loosen the protection. If I'm not mistaken, it was the wiring on the left side between the transmission and the engine. If I'm not mistaken, it was the wiring on the left side between the transmission and the engine. Our machine was a European version so I'm not sure if an American version has the same wiring.
Good luck
