perhaps you overlooking the switch it self, it may be getting power but is not "transmiting" it.(switch is bad) or the wiring fro the switch to the motor.
It is probably embedded in the rear window glass. In convertible models I believe it is inside the passenger door.

I have a 1972 Corvette and the power window relay is in the shifter console, just forward of the power window switches. I would believe it's in the same place in the '73. Good Luck
