I am still trying to troubleshoot the lack of any seat movement except the lumbar support in my driver's seat. Can I switch the known good passenger controls which appear identical to try moving the driver's seat? What is the grille cover on the floor directly under the front near side of the driver's seat covering? Those holes probably serve their function well, but could let rain run straight unto the compartment. I have looked at the circuit board inside the seat button case; there is no sign of water damage. There was a definitely deluge occurring the last time the seat worked and prior to the driver's seat restraint light appearing. Is there a pin out available for the F15? I miss not having a Bentley service manual.
