Which of these does your vehicle have ?
Power Windows Description and Operation (W/O AXC/AXE)
Power Windows Description and Operation (RPO AXC/AXE)
Do you know what a RPO code is ?
Need to know which one because one is basic an the other has electronic modules involved , driver door module , BCM - body control module , passanger door module etc..... Both power window circuit's use a circuit breaker an not a fuse . Would not think that being the problem . Broken wire's inside the flex boot from the body to the door maybe.
Power Windows Malfunction (AXC/AXE)
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 switches that control all power window operations. The power window switch contained in the PDM controls the front passenger window operation only.
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 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 right side passenger windows from the master switch, a 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 serial data message to the appropriate window motor to move the window as requested.
When the DDM receives a request to operate a rear window from the master switch, a serial data message is sent to the BCM. The BCM examines the request and checks for messages from other vehicle control modules prohibiting the window movement. If no prohibitive messages have been received, the BCM will send a serial data message to the appropriate rear window switch which will command the window motor as requested.
Power Windows Malfunction (Except AXC/AXE)
The power window system will operate any time the ignition is in the ACC or RUN position. The power window system will also operate whenever the body control module (BCM) is in the retained accessory power (RAP) mode. The driver power window switch contains individual window switches for each of the power windows. All windows may be controlled up and down from the driver master control. The individual passenger power window switches will only control the up and down operation of their respective power window.
Each power window contains a reversible power window motor. The direction the window travels is dependent upon the polarity of the supply voltage. By reversing polarity of the supply voltage the window motor will move up or down. Each power window motor is internally circuit breaker protected.
Battery voltage is supplied to each power window switch through the accessory voltage supply circuit. The power window switch also receives a constant ground source. The power window motor control circuits are connected to ground through the normally closed up and down contacts of the power window switch. When the power 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 power window motor. Since the other side of the power motor is connected to ground through the normally closed contacts of the up switch, the window travels down. By placing the power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.
