The passenger window is coming down. It is not the motor or the master swicth

The next step is to check voltage at the motor while pressing the switch.

A common problem is for wires to break in the rubber boot in the door jam, pull back the boot and check for broken wires carefully. I have seen this before and I am able to repair the wires and get the window working again.

You are going to need a volt meter to diagnose this if you cannot find any broken wires in the jam.

I did check and did not see any broken wire
the window goes up and if I reverse the polarity of the motor plug it goes down
is there a separate fuse or something else to move the window down?

There is a passengers multiplex control unit.
