It could be a switch, if you pull the door card off and unplug the connector off the motor and put a test lamp across the two terminals in the plug and operate the switch the lamp should light up, if it does it is most likely the motor, if it doesn't then it is most likely one of the switches, either the master of the slave switches.
Is it an update or pre-update as I have pre-update parts that I have tested.....
