I1999 Silverado 6.0. Passenger side power window inop.

check fuses -relays are you getting power to switches /motors check and test power feed

the window motor may be out or wires loose

What's with the 1994 C/K 2500 above an 2007 Silverado ? 07 on 94 frame ? New body have all the 07 electronics ?
Power Window System Controls (RPO A31/AN3/DL3)
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The driver master control switches are integrated into the DDS. When a power window switch is activated in the up or down positions the DDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the DDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist and during window motor operation the DDS continues to monitor the motor current to verify proper window motor operation.
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)

Passenger Power Window Inoperative

1. Ignition OFF, disconnect the C1 harness connector at the PDS.
2. Test for less than 1 ohm between the ground circuit terminal 6 and ground.
?‡'
If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
?‡'
If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

4. Ignition OFF, reconnect the harness connector at the PDS.
5. Ignition ON, observe the scan tool Passenger Window Switch parameters while using the passenger power window switch. The reading should change between Off/Up/Down/Express Down.
?‡'
If the parameter does not change, replace the PDS.

6. Ignition OFF, disconnect the harness connector at the passenger window motor.
7. Connect a test lamp between control circuit terminal A and control circuit terminal B.
8. Ignition ON, command the passenger window UP and DOWN by using the passenger window switch. The test lamp should illuminate when commanding the UP and DOWN states.
?‡'
If the test lamp is always OFF during either of the commands, test for a short to ground or open/high resistance on either control circuit. If the circuits test normal, replace the PDS.



?‡'
If the test lamp is always ON, test for a short to voltage on either control circuit. If the circuits test normal, replace the DDS.


9. If all circuits test normal, test or replace the passenger window motor.

not sure what you need power goes to the master window switch then to the drivers window motor then the drivers switch that goes to the passenger side in a series so the drivers switch for the passenger side can be bad causing the passenger window to be inop of work up from one and down from the other

Motor is not turning in second direction to lower window. Either the new motor is defective or the device that reverses the electricity to the motor is defective. Regulator?

Take motor out and feed it juice - will turn. Reverse polarity and it should turn in other direction.

you will need a new window motor that you can find on ebay the clicking sound you hear is a relay built into the passenger side switch to control the window motor.

any restriction under the seat
fuses or relays knocking out
ground circiut check
motor

This may be just a case of inadvertently hitting the window lock out n th driver door window switch by mistake. Check that first. Here's some background on window operation

Principles of Operation
The driver power window regulator motor is controlled directly by the master window/door lock/unlock switch (and its integrated "auto down" module). Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The driver power window regulator motor is a reversible motor that is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The passenger power window regulator motor is controlled directly by the passenger power window switch and can also be controlled by the master window/door lock/unlock switch. Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The passenger power window regulator motor is a reversible motor, which is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The power rear quarter glass is also directly controlled by the master window/door lock/unlock switch. The power rear quarter glass power latches also utilize reversible motors. The power rear quarter glass power latches are operated by applying power and ground to the motor leads to open the window, and then reversing polarity on those same leads to close the window.

I wouls suspect you have either a inoperative window regulator (the frame work for the power glass) or a bad power window motor. More often then not the are sold as a single assembly and are not very hard to replace on this vehice.
