My driver window works but none of the passenger windows do? What could be issue on 1997 Mercedes-Benz E420

None of the passenger windows roll up or down neither from the switch on the window nor the switches on the center console near the gear shift.

Defective master switch.

Replaced master switch and windows still don't work, just the driver side works. Could it be the regulator motors?

No way all could be bad. Possible broken wire where drivers door hinges.
