Rear Passenger Power Window Operation
The rear passenger power window switches receive battery voltage through the window lockout control circuit if the window lockout function is disabled. Ground for the rear passenger power window motors is supplied through normally closed up and down contacts of both the rear passenger power window switches and the driver power window switch. When the either rear passenger power window switch is placed in the down position, the power window motor down control circuit is switched to 12 volts and is applied to the down side of the rear passenger power window motor. Since the other side of the rear passenger power motor is connected to ground through the normally closed up contacts of both the rear passenger and driver power window switches, the window travels down. By placing the rear passenger power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.
The rear passenger power windows can also be controlled from the driver power window switch.

Did you try pushing the lock out switch on the drivers master switch ?

Rear Window Defogger System Components
The rear window defogger system consist of the following components:
?€¢
HVAC control module

?€¢
Liftgate module (LGM)/endgate module (EGM)

?€¢
Rear window defogger grid

Rear Window Defogger Operation (With LGM)
Battery positive voltage is supplied through the LGM 2 fuse to the LGM for the rear window defogger system. When the rear window defogger switch is depressed, the HVAC control module illuminates the rear window defogger indicator, and sends a class 2 message to the LGM to enable the rear window defogger. The LGM enables the rear window defogger by allowing battery positive voltage to the rear window defogger.
When the rear window defogger switch is pressed for the first time, the defogger cycle lasts 10 minutes. Further operation results in 10 minute defogger cycles.
DTC B0283 Electric Rear Defrost Circuit - do you know what DTC'S - diagnostic trouble code's are ?
Circuit Description
The liftgate module (LGM)/endgate module (EGM) monitors the voltage level on the supply voltage circuit of the rear window defogger. The LGM/EGM test the supply voltage circuit of the rear window defogger every 160 milliseconds. With the rear window defogger inactive, the supply voltage circuit of the rear window defogger will have no voltage present. With the rear window defogger active, the supply voltage circuit of the rear window defogger will be near system voltage.

GENERAL PROCEDURES Rear Window Motor Initialization CAUTION: Make sure that no obstructions are present in the power rear window system when carrying out this procedure.
NOTE: This procedure must be carried out when repairs are performed on any part of the power rear window system including when: the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window module is installed, and any operation in which grease or lubricants are applied to the power rear window system.
NOTE: All power rear window components (window glass module, window regulator, window motor, and glass runs) must be installed and torqued to specification before carrying out this procedure.
NOTE: Steps 1-6 must be completed within 30 seconds. The entire procedure must be completed within five minutes.
NOTE: Once the ignition key is turned to the ON position in Step 6, it must remain on until the entire procedure is completed.
NOTE: Steps 7 and 9 require that the power rear window control switch be held in the closed position until the power rear window motor stalls the window in the upper header seal. Step 8 requires that the window control switch be momentarily turned to the open position.

1. Start with the ignition in the OFF position.

1. Turn the ignition to the ON position.

1. Press the power rear window control switch vent button six times.

1. Turn the ignition to the OFF position.

1. Press the power rear window control switch vent button six times.

1. Turn the ignition to the ON position. The power rear window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has entered initialized mode.

1. Rotate and hold the power rear window control switch to the closed position until the window stalls in the upper header seal.

1. Momentarily rotate the power rear window control switch to the open position and release. The power rear window will carry out a one-touch down operation until the window stalls at the bottom of the travel stop designed into the window regulator.

1. Rotate and hold the power rear window control switch to the closed position until the window stalls into the upper header seal. Once this operation is complete, the window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has been successfully initialized.

1. Verify correct operation of the power rear window by moving the window to the fully open, vent, then fully closed positions.

Rear Window Defogger Description and Operation
Rear Window Defogger System Components
The rear window defogger system consist of the following components:
• HVAC control module
• Liftgate module (LGM)/endgate module (EGM)
• Rear window defogger grid
Rear Window Defogger Operation (With LGM)
Battery positive voltage is supplied through the LGM 2 fuse to the LGM for the rear window defogger system. When the rear window defogger switch is depressed, the HVAC control module illuminates the rear window defogger indicator, and sends a class 2 message to the LGM to enable the rear window defogger. The LGM enables the rear window defogger by allowing battery positive voltage to the rear window defogger.
When the rear window defogger switch is pressed for the first time, the defogger cycle lasts 10 minutes. Further operation results in 10 minute defogger cycles.
Rear Window Defogger Operation (With EGM)
Battery positive voltage is supplied through the EGM 2 fuse to the EGM for the rear window defogger system. When the rear window defogger switch is depressed, the HVAC control module illuminates the rear window defogger indicator, and sends a class 2 message to the EGM to enable the rear window defogger. The EGM enables the rear window defogger by allowing battery positive voltage to the rear window defogger.
The following conditions must be met for rear window defogger to operate:
• The end gate glass position is not below the index position.
• The window express down movement is not requested.
• The window down movement is not requested.
If the end-gate glass is not fully closed, the DIC displays "Tailgate Glass Down" when the rear defogger operation is attempted.
When the rear window defogger switch is pressed for the first time, the defogger cycle lasts 10 minutes. Further operation results in 10 minute defogger cycles.
