Driver side power window works, passenger side doesnt witheither switch. Took door panel off motor works when jumped. Checked my switched voltage and ground at the connector and I have voltage but no ground. Where do i go from here thankyou
The motor is grounded through the contacts in the passenger’s power window switch and the passenger multiplex control unit.
Possible broken wire or corroded terminal at connector or wiring at passenger door jamb. Check the wiring at Connector C464, specifically the blue wire at terminal no. 12 and the blue/yel wire at terminal no. 17.

ok I will check those. Is it common to see the multiplex unit fail or the switch
The multiplex control unit and switch are less likely to fail unless something like corrosion from moisture/water, bad/old solder joints, etc. affected them. There are three multiplex control units in the circuit (driver's door, driver's under-dash, and passenger under-dash).
The wires and connections at the door jamb are more likely; but, nothing can be ruled out. Door are opened frequently throughout the life of the vehicle, especially, the driver's door; so, you may also want to check the wiring and connector on the driver's door jamb too.
This is a description of how the passenger power window works:
Passenger Window
Once you turn on the main switch in the master panel, the passenger window can be operated from the passenger’s door switch or from the master panel. When you open or close the passenger’s window from the master power window switch, the door multiplex control unit sends a signal to the driver’s multiplex control unit through the BRN wire. The driver’s multiplex control unit sends this request to the passenger’s multiplex control unit and turns on the window motor by supplying voltage to the motor in the proper direction.When you move the passenger’s power window switch to UP, voltage is applied to the passenger’s power window motor. The motor is grounded through the contacts in the passenger’s power window switch and the passenger multiplex control unit. The window then moves up as long as you hold the switch in the UP position. If you move the passenger’s door window switch to DOWN, voltage is applied in the opposite direction, and the window moves down as long as you hold the switch in the DOWN position.

All circuits that you gave checked out ok no opens or shorts
Power windows need help
