Look at the diagram carefully.
The 2 wires from the driver power window switch:
VT/WT( connected on the push down side of the passenger power window switch) and BR/WT(connected on the push up side of the passenger window switch.
Now, if the passenger switch is diffective on the down side, it won't matter if you use the driver switch.
The up side works, that is good news for the motor but not the switch.
Check the wireVT/WT for open.
If it good. Check power at the connection on that wire to the passenger switch(down position)
if there is power, change the switch.
