The power window in the right rear backseat is broken

Did the switch work before replaced battery ? 2008 CTS ? Cadillac ? These switches are inputs to a control module , DDM - driver door module . a computer of sorts . A lot of thing's can go wrong with these systems , broken power or ground circuits inside the rubber boot from the body to the driver door . Communication problems between control modules etc... Plus the power windows don't use fuse's , has a circuit breaker for front windows - PWR/WNDW circuit breaker 25 amp located in the fuse box under the back seat , Fuse's are used for rear windows - two 15 amp fuse's LT/REAR an rear ,both are in the rear fuse box under back seat. These rear windows are controlled by the BCM - body control module .

The power windows system consists of the following components:
• Driver door module (DDM)--GMLAN device that receives and transmits messages and signals for window functionality. The DDM contains the driver door switch (DDS) which is integrated into the module. The DDS contains the driver, front passenger, RR and LR window and window lockout switches.
• Passenger front door module (PDM)--GMLAN device that receives and transmits messages and signals for window functionality. The PDM contains the front passenger door switch (PDS) which is integrated into the PDM. The PDS contains the front passenger window switch.
• Left rear power window switch--Provides switched voltage and ground window switch signals to the left rear window motor for left rear passenger window operation
• Right rear power window switch--Provides switched voltage and ground window switch signals to the right rear window motor for right passenger window operation
• Left front power window motor--Contains position sensors and a module that receives signals from the DDM and provides a status signal to the DDM
• Right front power window motor--Contains position sensors and a module that receives signals from the PDM and provides a status signal to the PDM
• Left rear power window motor--Contains position sensors and a module that receives signals from the left rear power window switch
• Right rear power window motor--Contains position sensors and a module that receives signals from the right rear power window switch
• DRIVER DR MOD fuse (15-amp)
• PDM fuse (15-amp)
• PWR WNDW Circuit Breaker (25-amp) -- front
• LT/REAR/WNDW fuse (15-amp) -- rear
• REAR/WNDW fuse (15-amp) -- rear


Power Window Operation
The driver and front passenger doors are equipped with power window motors that contains its own module. Each power window motor receives a hot at all times battery supply voltage and constant ground source. When the right front passenger window switch on the DDS is activated to the up or down position, the DDM will interpret the signal and send a GMLAN serial data message to the PDM. Upon receipt of the message, the PDM will send a signal to the front passenger window motor module on the GMLIN serial data circuit. The window motor module will then supply battery voltage and ground to the window motor to drive the window motor to the up or down position.
The DDM communicates via the GMLAN serial data circuit with the body control module (BCM) to control the rear window functions from the driver master window switch. The BCM is hard wired to each rear power window switch with circuits for window up, window down, and an enable circuit. The rear window switches contain internal logic that when supplied with voltage from the BCM over the enable circuit will driver the appropriate window in the direction commanded.
The rear power window switches are supplied with battery voltage from individual right and left WNDW fuses located in the rear fuse block. When a rear power window switch is activated to the DOWN position, voltage is applied to the motor down circuit and the motor up circuit serves as the path to ground. The window motor will drive in the downward direction until the switch is released or the window has fully opened. When the window switch is activated to the UP position, voltage is applied to the motor up circuit and the motor down circuit serves as the path to ground. Ground for the left rear power window switch is supplied at G200 and the right rear power window switch receives ground at G201.

The power locks work the same .

After replacing the driver door switch (DDS) or passenger door switch (PDS), perform the programing procedure.

If you don't know any of what i posted your best bet , have a qualified repair shop check it out .

Are all windows not working ? Two separate circuit breakers left & right . Both in rear fuse box . Fuse Block - Rear Beneath the left rear seat
Check for broken wires inside the rubber boot from body to doors.
Do you know about electronic control modules ?
The power window system consists of the following components:
?€¢
Driver door module (DDM)

?€¢
Passenger door module (PDM)

?€¢
Body control module (BCM)

?€¢
LR power window switch

?€¢
RR power window switch

?€¢
Window up and window down relays in each of the rear passenger window switches

?€¢
Window lockout switch

?€¢
Reversible power window motors in each of the doors (circuit breaker protected)

?€¢
LT DOOR CB 25A (System power for left rear window)

?€¢
RT DOOR CB 25A (System power for right rear window)

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 DDM contains 4 power window switches which are integral components. Closing any of the normally open, rocker type switches provides the DDM with a request for power window operation. The switches for the 2 front windows have 3 positions Up, Down and Express Down, while the switches for the rear windows have only 2 positions, Up and Down. Each of these switches and their positions is a direct input into the DDM. Upon receiving a request for power window operation, the DDM, transmits a class 2 message indicating the switch and it's changed position.
The PDM contains a single power window switch that is an integral component. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation. The switch for the front passenger window has 2 positions Up and Down. Each of these switch positions is a direct input to the PDM.
The 2 rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows. However the BCM, upon receiving a class 2 message from the DDM, can control the set of relays which will activate the rear window motors.

If you can hear the motor running and the window does not move than the wire in the regulator has probably broken. The rear door panel will need to be removed to access the regulator. Regulators are pretty common and should be in stock at just about any good parts store. I like the Dorman brand of aftermarket regulators and have also has good luck with the NAPA brand as well.

Hello,

If you want to fold down the rear seat when the strap is broken there is a solution to help you out,please follow the instructions given below;

1.Take a flashlight and look down into the square recess where the two seat belt locks come up through the backseat.
2.Besides the straps you will see two pieces of metal, one in "J" shaped and inside of the "J" you will see another piece right in the middle.

3. Take a screw drive and press down on the one that's inside of the "J" while you are pulling up on the strap. The seats will lift out.

That's it,problem solved,so funny you just will have to do that each time.



Thank you for using fixya.

Can you hear the motor turning in the door? If not, that is your problem - bad motor, loose connection......

If you hear it, the window regulator is probably broken. Google it for details. To fix it in a maxima was $75 (cost of part).

The power window regulator is broken. It will need to be replaced to fix this problem. Click on the link below to get a replacement:

The backseats of this vehicle do not fold down. They are placed on hooks and then they're bolted in on the bottom right and bottom left of the seat.
