Your diagnosis of the switch seems ok, but when you jumpered the switch did
you still have good voltage on post 1? A high-resistance on the green could
supply enough power to light your lamp but not to power the motor.
Similarly did you check that you had voltage at the connectors by the fan
motor? If you have voltage on both the green/yellow and the black the
problem is a bad ground. If it is on neither it is bad wiring between the
switch and the motor. If it is on the green/yellow but not the black it is
a bad motor, but always check both sides of ther bullet connectors.
