The HVAC control module monitors the voltage level on the supply voltage circuit of the rear defog relay. The voltage level should be low while the rear defog relay is de-energized. The voltage will be near system voltage when the HVAC control module energizes the rear defog relay.

Conditions for Running the DTC

Battery voltage must be between 9-16 volts.

Conditions for Setting the DTC

The HVAC control module detects a short to battery or open/high resistance in the defog relay coil control circuit for 1 second or greater.

Action Taken When the DTC Sets

1. The HVAC control module stores the DTC to memory.
2. The rear window defogger will not operate.

Conditions for Clearing the DTC

1. The DTC clears when the fault is no longer detected.
2. The current DTC will become history when the request for the output is removed.
3. The history DTC will clear after 50 consecutive fault-free ignition cycles have occurred.

The front and rear power windows are controlled by the driver door module (DDM) and front passenger door module (PDM). The DDM and PDM each contain power window switches that are integrated into the module. The DDM contains the master power window switch that controls all power window operations. The DDM supplies the left rear power window switch with a 12-volt reference and signal circuit. The power window switch contained in the PDM controls the front passenger window operation only. The PDM supplies the right rear power window switch with a 12-volt reference and signal circuit.

When the driver power window switch is activated to a desired position, the DDM examines the request and checks for messages from other vehicle control modules prohibiting window movement. If no prohibitive messages have been received, the DDM will send a LIN serial data message to the driver door window motor to move the window to the desired position.

When the DDM receives a request to operate one of the right side passenger windows from the driver master control, a GMLAN serial data message is sent to the PDM. The PDM examines the request and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the PDM will send a LIN serial data message to the appropriate window motor to move the window as requested.

The DDM and PDM supply their respective rear power window switches with a 12-volt reference and signal circuit. The rear power window switches contain separate resistors for each switch position. When a rear power window switch is activated, the associated door control module interprets the signal and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the door control module sends a LIN serial data message to the appropriate power window motor commanding the requested window position.

Power Windows System Components

The Power Window System consists of the following components

1. Driver Door Module (DDM)
2. Front Passenger Door Module (FPDM)
3. Left rear door switch
4. Right rear door switch
5. Window regulator motors in each of the doors
6. DR MDL/PWR WNDW circuit breaker 25-amp

Power Windows System Controls

The driver power window is controlled by the driver window switch which also serves as the master switch for all windows. The passenger windows can be controlled by the power window switches located on the driver power window switch or from the power window switch mounted locally on its associated door.

The power windows can be controlled in the following modes

1. Up
2. Down
3. Express Up
4. Express down

Driver Window Operation

When the driver power window switch is activated to a desired position, the DDM examines the request and checks for messages from other vehicle control modules prohibiting window movement. If no prohibitive messages have been received, the DDM will send a LIN serial data message to the driver door window motor to move the window to the desired position.

When the DDM receives a request to operate the a right window from the driver master control, a GMLAN serial data message is sent to the FPDM. The FPDM examines the request and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the FPDM will send a LIN serial data message to the appropriate right window motor to move the window as requested.

Rear Window Operation

The DDM and FPDM supply their respective rear power window switches with a 12-volt reference and signal circuit. The rear power window switches contain separate resistors for each switch position. When a rear power window switch is activated, the associated door control module interprets the signal and checks for messages from other vehicle control modules prohibiting the window movement.

If no prohibitive messages have been received, the door control module sends a LIN serial data message to the appropriate power window motor commanding the requested window position.

Express Down Feature

The driver window will travel to the fully down position when the driver window switch is pressed past the first detent. Pressing the driver window switch to the up position will cancel the express down feature.

Lockout Switch Feature

The window lockout switch is part of the driver master control. The lockout function is used to prevent the passenger door windows from being operated from their locally mounted switches. When the lockout switch is pressed momentarily, the switch contacts are briefly closed, the LED indicator on the switch button is illuminated, and the DDM processes the switch signal. The DDM sends the switch status via GMLAN serial data to the FPDM. Both the DDM and FPDM will prohibit the passenger windows from being operated from their locally mounted window switches. When the lockout function has been activated, the passenger door windows can still be operated from the driver master control

Rear Window Defogger

The rear window defogger system consists of the following components

1. HVAC control module
2. Rear window defogger grid
3. REAR DEFOG relay

Battery positive voltage is supplied at all times from the rear defog 3 fuse in the rear fuse block to the switch side of the REAR DEFOG relay in the rear fuse block. When the rear defogger switch is pressed in the HVAC control module. The HVAC then applies a ground to the REAR DEFOG relay. This energizes the relay and allows the battery positive voltage to be applied through the switched side of the relay to the rear window defogger grid. The rear window defogger grid is grounded at all times at G307 and G306.

The rear window defogger will turn off automatically after it has been activated. This time is determined by a dynamic timer which varies the amount of time the rear window defogger is allowed to be on based on ambient temperature and vehicle speed. The rear window defogger will be extended when the ambient temperature is cooler or while the vehicle is in motion.

If the battery is low, the BCM will send a signal to the HVAC, which in turn will disable the rear window defogger by not providing voltage to the REAR DEFOG relay.
