Driver Side Window Switch/Motor

colwell3

I'm trying to determine if my motor or my switch needs to be replaced. All other windows work but the driver side window doesn't go up or down. I can't hear a noise coming from the motor. The overhead light doesn't dim when I activate the button either. My test light comes on with three different terminals at the switch connection. One being green/white (pin #16, pink/blue (pin #7, & red/black (pin #18) (only w/power turned on). What steps do I need to take to determine which one is broken?
