Sorry for the late reply.
Can you operate passenger door from master switch on driver door? I'd have to check wire harness going into passenger door, hinge side of door. The wire harness usually has a protective rubber boot covering. Pull the boot back far enough to access proper color wire for the system you want to check, voltage and ground.
I can't rule out the master switch.
