Power windows wont roll up or down on 2006 Cadlliac cts


With the electronic's involved ,your best bet would be to take to a qualified repair shop . The door 's have electronic control module inside that control door lock's an window operation . Hooking up a professional or factory scan tool an viewing input data an checking DTC'S - diagnostic trouble code's would be the first step any professional technician would do . You probably have no idea what these are ? Messing with these systems can render your vehicle unuseable if you do not know what you are messing with .

Power Windows System Components
The following components are used to control the power windows:
• Driver door module (DDM)
• Passenger front door module (PDM)
• LH rear door module (LRDM)
• RH rear door module (RRDM)
• Driver door switch assembly (DDSA)
• RH front power window switch
• LH rear power window switch
• RH rear power window switch
• LH front power window motor
• RH front power window motor
• LH rear power window motor
• RH rear power window motor
• Class 2 serial data link
• DR MOD PWR C/B 30 Amp circuit breaker
• DRIVER DR MOD 10 Amp fuse -- DDSA and DDM logic, DDM internal driver operation.
• PSGR DR MOD 10 Amp fuse -- PDM logic and internal driver operation.
• REAR DR MOD 15 Amp fuse -- LRDM and RRDM logic and internal driver operation.
Power Windows Operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a power window switch built into the driver door switch assembly (DDSA) , or, from a power window switch mounted locally on its associated door. The driver door window can be operated only from the driver door power window switch built into the DDSA.
When the driver door module (DDM) receives a driver door window switch request from the DDSA, the DDM examines the request and inspects to see if it has received any messages from any of the other vehicle modules prohibiting the movement. If no prohibitive messages have been received, the DDM then applies power and ground to the driver door window motor to move the window as requested.
When a passenger door module, passenger front door module (PDM), LH rear door module (LRDM), or RH rear door module (RRDM), receives a window switch request from, either the DDSA or the window switch mounted locally to its door, the passenger door module examines the request and inspects to see if it has received any messages from any of the other vehicle modules prohibiting the movement. If no prohibitive messages have been received, the passenger door module then applies power and ground to its associated window motor to move the window as requested.

So do yourself a favor an take it to a qualified repair shop.

Power Windows Operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally to its associated door. The driver door window can be operated only from the driver door window switch built into the DDSA.
When a window is operated from the DDSA, the DDSA interprets the window switch signal as a specific window switch request and sends the information to the driver door module (DDM) via the power door serial data circuit. The DDM examines the request and checks to see if it has received any class 2 serial data messages from any of the other vehicle modules (i.e. ignition switch position) prohibiting the movement of the window. If the window being operated is the driver door window, and if no prohibitive class 2 messages have been received, the DDM then applies voltage and ground to the driver door window motor to move the window glass as requested. If the window being operated is a passenger door window, and no prohibitive class 2 messages have been received, the DDM sends the request, via the power door serial data circuit, to the appropriate passenger door module. The passenger door module then applies voltage and ground to the passenger door window motor to move the window glass as requested.
When a passenger door window is operated from the power window switch mounted locally to its associated door, the passenger door module first checks to see if the DDM has received any prohibitive class 2 serial data messages. If there are no prohibitive messages, the passenger door module powers the associated passenger door window motor.
Both front door windows have the express down feature. This allows the front door windows to be fully opened by momentarily pulling the appropriate window switch lever to the second detente and then releasing.

2008 Silverado. I have no power to either drivers side window. Driver's switch will not work for either drivers side window. The rear driver's side switch won't work the window. I doubt it both motors and...


Circuit breakers rearly fail an they reset them selfs . You could have broken wires inside the flex boot from the body to the drivers door . Taking the door panel off an check for B+ voltage to the switch an a good ground would be a good test to do. But first reading up on how these systems work would be good thing to do.
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)

Rear Passenger Power Window Operation (RPO A31/AN3/DL3)
The body control module (BCM) monitors the window UP/DOWN command from the DDS. When the rear window UP or DOWN command is received, the BCM sends a signal to the appropriate rear window switch. The rear window switches continuously monitor the up and down signal circuits, if no function is being commanded, the signal voltage is at approximately B+ voltage. If the UP or DOWN function is commanded, the BCM signal voltage drops approximately 5 volts and the appropriate rear window switch will then command the window in the UP or DOWN direction.
DTC B3819 00: Left Rear Window Up Control Circuit
DTC B3820 00: Left Rear Window Down Control Circuit
DTC B3822 00: Right Rear Window Up Control Circuit
DTC B3823 00: Right Rear Window Down Control Circuit

Having the vehicle checked for DTC'S mite be a good idea .

2004 gmc envoy window won't go up rear wiper obstruction


I know this question is old, but I am responding so others with the same problem can see. I wired the Rear Window Motor Park Signal wire and the Rear Window Motor Speed Signal wire together and it completely bypassed the rear wiper motor. Now the window goes up and down. This doesn't fix the rear wiper motor, but you will be able to have access to it now that the window is out of the way

I made and album to show.

Cannot get the rear window to stay up . the drivers side rear window slides down as I drive.


Either the window fell off the track or the motor is faulty. You will most likely have to remove the screws and then pry off the door panel to access the window, frame, and motor
