Window dead; did broken switch fry motor?

Redirected my 964 turbo after a motor transplant but pass window is dead; tried a combo of all three switches & replaced a bad regulator fuse#4 but window still dead; did the broken switch on pass side fry something common??

Did you put 12V directly to window motor? On the passenger side switch, pull the switch plug and connect 12V and ground to pins 1 and 2, I think. I will check my wiring diagram.

I'd like to further diagnose this w/o pulling the door apart if testing the wiring from the switch to the motor doesn't work...but feel I don't have a choice at that point. Pin's 1 & 2 are labeled I assume??

If you have checked you are getting power to the motor I would suspect the motor is seized operate the switch in the down position and tap the motor with a hammer, my passenger side window has a tendency to seize now and again a few thumps on the door card is usually enough to get it working
