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 .
Yes they run a wire loom that has wires that are not used in some models. One thing you need to check is the wire loom because it flexes every time the door opens and closes and wires can break .Also you may want to go to autozone website and make a free account, you can put in the year make and model and look for the free repair guides for wire diagrams.
All - driver - passenger - front an back ? Look for broken wires inside the rubber boot from the body to the door ,driver side !
Power Windows Operation
Power Windows
The vehicle is equipped with power windows controlled by the door modules. The DDM receives a window switch request, over the SBI serial data, from either the passenger door module wired to the window switch pressed or from the driver door switch assembly. The DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation.
If the status information to permit window operation is correct, the DDM sends the command to the door module controlling the window to move the window as requested.
Windows Power and Ground
The windows are powered by discreet power and ground circuits. These circuits are in the same dedicated connector as the window motor drive circuits.
PWR/WDO 30 amp circuit breaker located in the rear fuse box ,DRVMDL fuse 10amp located in the same rear fuse box . This power the driver door module (computer )
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door. The driver door module (DDM) is the master control for the door lock system but the rear integration module (RIM) contains the program that determines when the lock functions are permitted.
The exterior key cylinders are wired to either the DDM or the passenger door module (PDM), depending on the location of the key cylinder. The interior lock switches are wired to the driver door switch assembly (DDSA) and the PDM. The DDSA and the PDM send the lock switch requests to the DDM over the simple bus interface (SBI) serial data circuit. The DDM then sends the lock requests to the RIM over the Class 2 serial data circuits.
The door lock operation modes are controlled by the rear integration module (RIM). The RIM examines the requested function from the DDM, or the remote function actuator (RFA), as well as the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. The RIM determines if a locking function is permitted, and commands the DDM to perform the function permitted. The DDM then sends commands to the rest of the door modules via the SBI to implement the selected locking function.
All programmable modes of lock system operation are stored in the RIM. The RIM checks the lock function program selected against the lock requests, the transmission selection and ignition key switch condition to determine if the requested function is permitted. If the requested function is permitted, the RIM then commands the DDM to perform the lock function over the Class 2 serial data circuits. The DDM commands the individual door modules to perform the lock function over the SBI serial data circuit.
So no windows work? Is the window safety lock off? . What year and model? Some power windows have fuses, some have relays, and some (most) have circuit breakers which automatically reset.
One thing all have in common is that the driver's door switch is called the master switch. From the (?circuit breaker?), and with the key on, one hot wire will come into the master switch connector- it is only hot in on or run. And the ground for the power windows starts at this switch and goes back into the cabin to a nearby ground. If no windows work and no liquid was just recently spilled on the master switch, you need to check for broken wires in the door opening. The multi-wire harness in the door opening may be covered by a rubber boot-peel it back or take it off and check the wiring. The ground wire is usually black. A wiring diagram would indicate the color of the power wire. If you have a voltmeter or test light, and can get at the connector for the master switch, turn the key to on and probe all terminals in the connector. There should be one hot wire to the connector for the windows. If you have it, and it is not for the locks or some other function, then possibly the master switch is bad or the ground wire is broke or not connected.
On some vehicles, the master switch can be removed from the door panel to get at the connector. On others, the door panel has to be removed first to get at the switch and connector.
I don't know liter size of engine? May not matter. You see the power window circuit breaker, not only check the circuit breaker, check the circuit for voltage, use a test light. The circuit goes hot with key on.
You can also check wiring harness on hinge side of driver door. When trying to operate window, the tan wire is voltage and black wire is ground. Sometimes those wires break because you open and close the driver door so much.
I just solved this same problem on my 1989 Camry. The problem was a broken wire somewhere in the door or rubber boot, running between the master switch in the drivers door and the connector (E1, 10-pin blue connector) in the left kick panel. Put one lead of your ohm meter on the pin with the GRN/WHT wire (green with a white stripe) on connector E1, and the other lead of your meter on the same color wire at the master switch connector. If your problem is the same as mine you'll find this wire is broken (no continuity). Try some of the other wires in the same way to ensure you have the right wire bundle. The fun part was fishing a new 16 gauge wire through the boot. I used a fiberglass wire pulling rod from Harbor Freight tools, pulled a heavy string through, tied the new wire to it, and pulled it through. Tip: Pull in some extra wires at the same time; I found another broken wire that stopped my left rear window from working also. I cut the wires near each connector and crimped on **** connectors to splice in my new wires. Works great. Good luck -- Mark
Maybe everyone is as befuddled as me! What kind of system lowers a window with a door key? This is a new one on me.
Usually, power windows have a circuit breaker, rather than a fuse in the circuit.
If you pull off the master switch on the driver's door, on the connector there, you should have one hot wire to the switch with key on in the ignition. You say no power to switches:is that because the switches don't work, or have you verified no power on any wire to the masterswitch?
If you do have a hot wire at the masterswitch, then likely you have a bad masterswitch, or the ground for the power windows may be loose, but that doesn't seem likely if you got the window to roll down with the key. If you don't have a hot wire to the masterswitch with key on, then you need to check the wiring going into the door. Maybe a wire got broke there. Good luck.
Here is a little information on how window regulator works. Also step by step instruccions on how to remove and install the window glass.
Door Glass & Regulator
Power Windows Diagnosis & Testing
When the rear window lockout feature is enabled, the circuit is open and no voltage is supplied to the rear window switches. When the feature is not enabled, the circuit is connected to battery positive voltage. If this circuit is shorted to ground when the lockout feature is not enabled, the PWR WDO circuit breaker may cycle continuously OFF/ON until, either the lockout switch is pressed to open the circuit, or the circuit breaker is permanently damaged. All windows may be partially or totally inoperative while the fault is present.
Inspect for aftermarket devices which could affect the operation of the system. Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom. Faulty electrical connections or wiring may be the cause of intermittent conditions. Removal & Installation Window Motor & Regulator
Position window approximately half way down in the door.
Remove the interior trim panel.
Remove the water deflector.
Tape the window to door frame to prevent it from moving.
Remove the three front door window regulator motor screws.
Disconnect the electrical connector from the window regulator motor.
Remove front side door window regulator motor.
To install, reverse removal procedure.
Window Switch Front
Remove the front door pull cup screws and pull cup from the front door trim panel.
Disconnect the electrical connectors from the front door power window control switch.
Remove the front door window control switch using a small, flat-bladed tool at the side of the switch.
To install, reverse removal procedure.
Rear
Remove the rear door pull cup from the rear door trim panel.
Disconnect the electrical connectors from the power window control switch.
Remove the rear door window control switch from the pull cup using a small, flat-bladed tool at the side of the power window control switch to release the power window control switch retainer.
Remove the power window control switch from the rear door pull cup.
REMOVE THE DOOR PANEL TO GET TO THE WINDOW MOTOR. REMOVE THE CONNECTOR ON THE MOTOR. LOOP A TEST LIGHT FROM BOTH TERMINALS. WITH THE KEY ON AND BOTH SWITCHES IN PLACE, CHECK TO OPERATION OF THE SWITCHES. IF THE LIGHT COMES ON IN BOTH DIRECTION THE WINDOW MOTOR IS BAD.
THERE IS A CIRCUIT BREAKER BUILT INTO THE WINDOW MOTOR. SOMETIME HITTING THE MOTOR WITH MAKE THE CIRCUIT BREAKER RESET BUT THE MOTOR WONT LAST LONG DOING THAT.
ALSO TRY PULLING DOWN ON THE WINDOW WHILE TRYING THE SWITCHES. THE WINDOW COULD JUST BE STUCK. THIS HAPPENED TO ME.
