LR window won't go up,motor been changed & switched been tested with other switch which tested good.Is there a fuse for this window.

I could see one window not working from a broken wire inside the door flex , but not both back windows . Back windows are controlled by LF door module . Both back windows have different grounds - LR G200 an RR G201 . Also both rear window switches have different power supply's .RR switch fuse # 18 30 amp . LR is fuse b# 9 40 amp . Both window motors or switche's going out at same time ???? wouldn't think so .

Doesn't have fuse for power windows . Has circuit breaker ,
System circuit breaker (POWER WDWS Circuit Breaker 30A )
Those rarely go bad .
Power Windows System Components
The power window system consists of the following components:
• Window master switch
• Front passenger window switch
• LR window switch
• RR window switch
• Window motors in each of the doors
• System circuit breaker (POWER WDWS Circuit Breaker 30A)
Power Windows System Controls
The power windows system can be controlled by a power window up or down switch activation.
Driver Window Operation
When the ignition switch is in the RUN or ACCY position, or retained accessory power (RAP) is enabled and the window master switch is activated to the DOWN position, battery positive voltage is applied to the window motor causing the window to open. When the window master switch is activated to the UP position, battery positive voltage is applied to the window motor in the opposite direction and the window closes.
The window master switch also controls the front passenger, LR, and RR windows.
Express Down Feature
The driver window will travel to the fully down position when the window master switch is pressed past the first detent. Activating the window master switch to the UP position will cancel the express down feature.
Lockout Switch Feature
The window master switch has a lockout switch which disconnects the battery positive voltage to the LR and RR window switches, disabling them.
Individual Window Operation
When the ignition switch is in the RUN or ACCY position, or RAP is enabled and an individual window switch is activated to the DOWN position, battery positive voltage is applied to the window motor causing that window to open. When the individual window switch is activated to the UP position, battery positive voltage is applied to the window motor in the opposite direction causing that window to close.

The only way to find the problem would be to view wiring diagrams an test the electrical circuits with a volt meter .

Check a wiring diagram an check power an ground for those systems . Also read factory service information on how they work . Electronic modules involved . DDM - driver door module . If this vehicle came to my shop , first thing I do , hook up factory scan tool an check input data from the door switch to the DDM . Check DTC'S - diagnostic trouble codes .

Your best bet , take it to a qualified repair shop.

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.

What fuse ? Your power windows has no fuse or no relay ! Has a 25 amp circuit breaker .Testing for power an grounds at the window switches would be a good place to start . Do you know how to do automtive electrical testing using a volt meter or a test light ? Using a wiring diagram so you know which wires to test . Here is a web site for free wiring diagrams . http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model an engine size . Under system click on body & accessories ,then under subsystem click power windows . Watch this video How To Diagnose your Power Window Problem Is the Switch or motor bad or no power to the window switch .

Ether the lr motor or switch is bad. Most likely the motor. Could you send me a picture of the switch on the front and back doors so can help you more?

If fuses and relays are good or new, your gonna have to check the window motor and switch next. You'll have to remove the door panel for this and a test light as well which can be found at your local auto parts. Once the door panel is off, leave the window switch plugged in. Connect your alligator clip on the test light to a ground source. Then find the 2 wires that go to the window motor. Make sure your ignition switch is on and stick the tip of the test light into one of the wires that go to the motor and try the window switch. If the test light turns on, stick into the other wire too. If the test light turns on when the switch is hit, you have a bad window motor. If the test light doesn't turn on when you try the switch for either wire, you may have a bad window switch or your main window switch at the driver seat (master switch) is bad. Hope this helps you out. Good luck.

check fuse first/ if good check wires at the switch for voltage if all good check for voltage going to window motor if no voltage replace switch if you have voltage (12) v change motor

first thing first check ur fuse for the power window. look at ur car manual to locate the switch box. if the fuse is good check the window motor by removing the door panal then locating it inside the door. use a power tester to see if power is getting to the motor by connecting it to the positive (red) wire connected to the window motor. if its not getting power the change the motor. if it is then you may have a window switch problem. if you have change the motor, switch, and fuse the you make have a wire shortage proble so take it to a payed professional for further advice or service. good luck

Most likely the window motor/regulator assembly has gone bad.Check for good fuse, if good pull out the switch and make sure you have power to it, if you do then remove door panel and test for power at motor, if u have power but motor won't work replace. Suggest replacing the regulator assembly as well because the cables often fray and cause problems as well.
