I would like to know the wiring diagram for the passenger side window switch. I'm trying to test it to see if it's just a switch that has failed because the motor works the regulator is fine, the fuses are good and so are the relays. Thank you

The easiest way is to unplug the window motor and use a test light to see if it is getting power and ground while you work the switch. This guide can help:
