I can't find the work order for mine, but I had the issue with BOTH interior and exterior handles, so you may be right about the microswitch. It doesn't not sound like it is a fault with the motor/control unit which was ~$500 in my case...

There is no "undo" switch but there is a "reset" done via the computer that might fix it. This is what my dealer tried before requiring a service appointment to diagnose and swap the motor unit.
