2003 Hyundai Elantra How do you disconnect driver door wiri

Electrical problem
2003 Hyundai Elantra 4 cyl Two Wheel Drive Automatic

Only down switch works on passenger side power window operating from drivers side or passenger side. I disconnected passenger window motor leads and reversed leads and windoe went up. About a year ago I had a dealer work on a similar problem and they replaced a broken in the door conduit which moves when you open and close the door. I know about about continunity testing but can't where the nearest connector to the flexing wires. I can see a white plastic under the rubber seal which I assume id a male female connector but can't seem to get it apart. Need help.
