Bad wiring? The wires that go between the car body and doors or in the center console - has someone spilled some coffee or drink in the center console? Is it just one window or several? (just one - I suspect door, several I suspect center console).

My 2013 VW beetle power windows are no longer working


You need to have the BCM (Body Control Module) put thru a self test, the windows are controlled via this computer module.

I have a 1998 cadillac saville none of the windows will roll down checked all fuses under the back seat and under the hood all fine.


The power windows on your vehicle are controlled by a electronic module .
Each power window is connected to a permanent magnet motor. The motor raises or lowers the glass when the door module applies voltage to the motor. The direction the motor turns depends on the polarity of the supply voltage provided by the associated door module. All four doors have their own separate modules.
A serial digital communications link, called the simple bus interface, is used for communications between door modules and the driver's door power window switches. The use of serial digital communications allows the use of a single wire to convey switching information between the LH front power window switch and the driver's door module. The serial communication is also used to transmit switching information from the driver's door module to the other three door modules.
The door modules apply battery voltage of the correct polarity to the respective window motor when any local, or power door lock switch, UP switch is operated, driving the window up. Battery voltage is applied to the respective window motor in the opposite polarity when any local, or power window switch, DOWN switch is operated, driving the window down.

The first place to start when diagnosing a problem like ths would be to hook up a factory scan tool , checking DTC'S - diagnostic trouble codes. Without a factory scan tool ,forget it , you have no chance of fixing this . Take it to a cadillac dealer . Could have problem with the
Simple Bus Interface (SBI) Serial Data Link
The simple bus interface is a serial data link. This serial data link replaces vehicle cables between various door modules with a single wire. The same amount of information is sent by multiplexing (time-sharing) data to and from each device over that wire. The serial data signals are referenced to ground. If the simple bus interface is lost, the RFDM, LRDM, and RRDM will enter the sleep mode. With the door modules in sleep mode, no power window operations are possible.

  • Power Windows Completely Inoperative
  • Window regulator control switch.
  • Circuits open or shorted.
  • Window regulator electric drive.
  • Driver door module.
  • PERFORM Self Test to retrieve Diagnostic Trouble Codes. If no DTCs retrieved, GO to Pinpoint Test C .
  1. VISUAL INSPECTION CHART
  1. Mechanical
  2. Electrical
  • Front door power window regulator damaged.
  • Front window run damaged.
  • Front door window glass out of window run.
  • Front door window glass broken.
  • Lighting control module.
  • Driver door module.
  • Circuits open/shorted.
  • Loose, corroded connectors.
  • Damaged window regulator control switch.
  • Damaged window regulator electric drive.
  • Power distribution box Fuse D 40 for heated back window concern; Circuit Breaker 14 (20A), Circuit Breaker F (30A) or window regulator safety relay for power window concern.
  • Fuse junction panel Circuit Breaker 14 (20A), Fuses 6 (10A), 9 (5A), 15 (15A), Fuse 13 (10A), Fuse 4 (10A) or Circuit Breaker 12 (18A).
  • Scratched grid.

  1. If the inspection reveals obvious concerns that can be readily serviced, correct the concern before continuing with Inspection and Verification.
  1. If the concern remains after the inspection, connect the Rotunda New Generation Star (NGS) Tester, 007-00500 or equivalent, to the data link connector (DLC) located beneath the instrument panel to perform DATA LINK DIAGNOSTICS test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the driver door module, go to Pinpoint Test A . If the NGS responds with NO RESPONSE/NOT EQUIPPED for lighting control module, go to Pinpoint Test B . If the DATA LINK DIAGNOSTICS test is passed for the driver door module and lighting control module, retrieve continuous DTCs and execute self test diagnostics for the driver door module and lighting control module to retrieve current DTCs.
  1. If self test is passed and no DTCs are retrieved, go to Symptom Chart to continue diagnosis.
  1. If DTCs are retrieved for the driver door module, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index to continue diagnosis. If DTCs are retrieved for the lighting control module, go to the Lighting Control Module (LCM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
  1. If the driver door module cannot be accessed by the NGS tester, go to Pinpoint Test A . If the lighting control module cannot be accessed by the NGS, go to Pinpoint Test B .
Rotunda Service Bay Diagnostic System (SBDS®) 001-00001 may also be used to diagnose this system.
You'll need more then wiring diagrams ! A good scan tool for starters .

My power seats and only the power windows on right side quit working on my 2007 silverado classic lt1500 I replaced the circuit breakers already and it did not fix the problem


Does you truck have Memory Seats ? There are 2 options of power seat systems available in full size trucks. The first is 6 way driver and passenger power seats without memory. The second is an 8-way driver seat plus 4-way lumbar with memory, heat and optional cool function.
If you replaced the circuit breaker , did you check for B+ voltage at the switch ? If you have memory seats there is a control module that is in the mix.
For the power windows same thing here ,the BCM - body control module is involved .A factory Tech 2 scan tool is still the best tool to use ,checking data parameters .
The switch for the front passenger power window has 2 positions UP and DOWN, and it's position is a direct input into the PDS. Upon receiving a request for power window operation (switch activation), the PDS supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to drive the window UP or DOWN.
The front passenger power window can also be operated from the driver master control. The front passenger window switch on the driver master control has 2 positions UP and DOWN and it's position is a direct input into the DDS. Upon receiving a request for front passenger power window operation, the DDS transmits a GMLAN message indicating the changed switch position. When the PDS receives this message, the PDS supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to move the window UP or DOWN.
GMLAN - is a data bus communication network that vehicle modules talk together on.
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.
Your best bet would be to take your truck to a GM dealer !

Electric windows go down on its own without key in ignition


Some year models of MKZ, maybe other Ford products too have problem with windows going down when the lock button is pressed on the ignition key. These models have a safety feature that when you press and hold for two second one of the buttons (look in your manual) on the ignition key the windows and sunroof will open. I was told by the dealer there is a problem with the receiver in car.

Driverside window stays down


there is a module that drives the regulator power window assembly.
the module(express widow module) is probably at fault.
if the module does not register that the window is all the way down,it will not allow the window to go up.

Electrical problem


Instrument cluster problem maybe . Without testing we'd only be guessing . Have seen this a lot at the dealer . The best thing would be to hook up a factory scan tool an check for DTC'S - diagnostic trouble codes first. The electronic's on these vehicles are complex to say the least . All the warning light's , gauge's etc.... are controlled by a module an data network . GM class 2 serial data buss. Power windows also are controlled by a module . DDM - driver door module.

Power Window System Components
The power window system consists of the following components:
• Driver Door Module (DDM)
• Passenger Door Module (PDM)
• Body Control Module (BCM)
• 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 windows)
• RT DOOR CB 25A (System power for right windows)

Your best bet , take it to the dealer .
