Cutlass Supreme Window Problem Part II!!

Well this time the passenger side window doesn't even move at all. it was working before and all of the sudden just quit. Neither the drivers side switch or the passengers side switch will open the front seat passenger side window.

I highly suspect the switch. How do i check switch with multimeter for front passenger door?

Should i

A. buy a cheapy plastic switch from kragen and "rig" it in there?
B. Go OEM?

Does someone other than a dealer carry this or is it dealer exclusive? Cost?

C. Wrong again, it's the motor? How to check with multi-meter?

See if you have power to the motor connector in the door, when using either switch.
