Back window While driving the back window sensor will send a door open signal. But the window is shut. How can I corret the problem

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 .

Each door opening has a switch that the door triggers as it opens and closes , one of the switches is faulty or the door is not making contact with the switch , try the rear hatch door switch first . as far as I know they are not computer connected .

Don't know how you read these codes but their is no H in back .

DTC B3832 or B3833
Express Up operation of the front door power windows is monitored and controlled by the front door modules, the window sensors, and the 4 connecting circuits. Each front door window motor has a window sensor mounted to it. The driver door module (DDM) and the passenger front door module (PFDM) each supply battery positive voltage and ground to power their respective window sensors. Each door module communicates with its sensor via a power window high speed serial data circuit, and a power window low speed serial data circuit. The window sensor detects differences in the window motors electrical pulses to determine if there is an obstruction to the travel of the window glass. The door modules use the information generated by the sensors to disable the Express Up movement of a window, or reverse the direction of travel, in the event that a passenger, or other obstacle, has become trapped in it.
The power window low speed serial data circuit is a unique 2-way serial data link between the door module and its sensor. The actual position of the window glass, in relationship to the distance traveled by the window, is communicated via this circuit, as well as state-of-health messages and the direction in which the window is traveling.


DTC B3832 may be set and the Express Up function disabled if the vehicle or the door module has recently lost power for any reason. You should first attempt to re-initialize the Express Up function. Refer to Window Motor Programming - Express Function .
If DTC B3832 is accompanied by DTC U1714, utilize the DTC U1714 or U1716 diagnostic table before using this table. Refer to DTC U1714 or U1716 .

DTC B1420
Battery positive voltage is supplied at all times to the seat adjuster switch and the memory seat module (MSM) through the same circuit. The MSM uses this battery voltage input to determine if battery positive voltage is applied to the seat adjuster switch.
DTC B1825, B1850, B1860, B2355, B2365, or B2375
Circuit Description
The position sensor that sets this DTC is attached to the seat directional motor. It receives a 5 volt reference and low reference from the memory seat module (MSM). The sensor sends a voltage signal that varies with the movement of the seat through the signal circuit to the MSM. Then based on this voltage signal, the MSM determines the position of the seat.

Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, observe the appropriate Sensor parameter in the Memory Seat Module Sensor data list.
Does the scan tool indicate that the Sensor parameter is within the specified range?
0.25-4.75 V

Sure you can move the seat back . Connector # 3 at the MSM ,pin's S & N - lite green & tan wires . Give a ground to one an B+ to the other ,if it moves in wrong direction switch the wiring around ..

its a switch with a rubber cover on it you can push it in and out, may just need a clean with some wd40 as they rarely go unless water is getting in the back of them.

One of the most common causes would be a faulty crankshaft position sensor. When the sensor malfunctions, it overheats and stops sending a signal to the computer. If the sensor stops sending a signal to the ignition module, it will cause the car to shut off. Replacing the crankshaft position sensor should cure this problem. There are a lot of other possibilities such as a faulty ignition control module. When the car stalls suddenly while driving it is usually due to loss of ignition spark. Clean all the fuses in the main fuse box. Some of the fuses provide power to the ignition system. If you have poor fuse connections it can cause the problem also. If you need more help on how to repair your crankshaft position sensor I would suggest checking out this sites HowTo section http://www.buyautoparts.com/howto/

This is the short story.The transmission sends a signal to the ECM that sends a signal to the BCM (This is what locks the doors) The ECM also sends that signal to the ABS. When the ABS doesn't sense a signal from the wheel sensors, the ABS light comes on. Have the codes checked. Let me know. Randy

you probably have two switches in your door. one for the door ajar and the other for the door handle. It sounds like the door handle switch is stuck; sending a constant signal to the module showing the door handle being actuated when in fact it is not.

one of the door sensor/switch is defective. it's sending a signal that a door is still open

one of the sensors in the door pillars has come loose.rear door is a problem as you will need to remove panel from inside to release mechanism,sometimes it can be done by lowering window , remove the rubber strips either side of window and with a coat hanger pulling the lever on the lock.if your lucky ,better off calling out your local mobile mechanic to open door for you

Somwhere along the lines someone might have installed an oxygen sensor eliminator kit. It basically sends a straight even signal back to the computer to tell it everything is ok. These are often used when people are trying to trick the computer on the vehicle to dump more fuel into the motor. I would check for a wire harness near the sensor that might just have a plug of some sort stuffed into it. If this is not the case, I would have to ask a few questions about the vehicle before I could give a more complete answer.
