This sounds like an internal electrical fault in the seat control module/ecu itself.I have seen this ecu fail internally before in the past and had to replace it for issues like this here.I have had seats become stuck like this on the CLK and wasnt able to correct this until the seat control module was installed and programmed to the vehicle.You can try and disconnect the battery for about 5 minutes (keep in mind you may need a radio code to reprogram the radio after this is done) to see if this resets the seat control module to correct this here.If this does not work let me know so we can continue from here to see if we can free the seat up.
