Question about Cars & Trucks

1 Answer

What would cause lack of power going to the drivers window but let all the other switches in the control panel work?

The motor and regulator are new. There is absolutely no power going to the drivers side window at all. There is also a new control panel.

Hi Kathryn:
Have you used a voltmeter to check the new control panel output? If there is no power to the drivers window, then the switching in the control panel may be defective. If there is output, then it should be getting to the window motor, and it should work unless it is defective, or possibly not grounded.
Hope this helps.

    Hi! The control panel was actually the first thing we replaced, after that didn't fix anything we replaced the motor and regulator. We ended up using the voltmeter yesterday. We learned that there was no power going to the motor at all. Today we applied an electric current to the motor and it worked but only while it was attached.

    This explains it better in a similar vehicle; "I have a 2000 Tahoe ("New Body Style") that the driver side window just quit working the other day. No sounds coming from the window, it doesn't even try to go up and down. All of the other windows can be controlled from the master switch, just not the driver's window. If I apply 12 volts to the motor, it goes up and down. I checked for voltage at the connector to the motor, and nothing happens when I opersate the switch. Thought the switch might be bad, so I replaced it with a new master switch. Now I have a nice lighted switch, but no response from the window. Any idea how to troubleshoot the door wire harness?"

    Hi AgainKathryn:

  • Ted Maxwell Apr 04, 2015

    Sounds like you've got it pretty well isolated. I'm coaching on logic now as I don't have a wiring diagram or one of those vehicles to tear apart. Can you confirm with the voltmeter, which wire(s) are the output for the problem window? I'm assuming that there is a multi pin/plug connector at the master switch, If you unplug it and then operate the switch, you should be able to determine which pin(s) are for the drivers side window. If you have an electrical schematic for it, all that testing would not ne necessary. If I'm understanding you correctly, the motor has pin/plug connectors, as does the master switch. Try to match the colors of the wires at the problem motor with the same colour wires at the pin/plug that would connect to the master switch. Use a continuity meter to try to find where the break in the circuit is. Can anyone else out there explain how the regulator is involved?

    We found the problem! There's a wire that goes from the motor to the main wire circuit that was dead. So we have to go to the dealership because none of the auto shops have the proper wire needed. (I live in alaska)

POWER WINDOWS NOT WORKING & POWER WINDOW/REGULATOR ISSUES


It can be issue with motor itself. If it's not going up, then how its working down. But still it feels like weak window motor or is issue with power window switch. Get the voltage tested at switch and motor. Also try another working window motor at not working window side.

Power lock and power windows dont work can`t find fuse


Number 21 is for the door lock fuse and relay, its a 10 amp fuse.
Number 7 is for the body control module, its a 10 amp fuse.

The fuse panel is under back seat.If all fuses checked out ok,then its faulty drivers door module called as DDM.

My 1995 Honda Accord power windows just stopped working. Drivers side is fine. It is the rear 2 windows and the front passenger side will not go up. Checked fuses they were all fine. any suggestions?...


It could be the motor of the power windows.

  • Troubleshoot
    • 1

      Check the fuses and switches. Your owner's manual and fuse-box cover have fuse and switch diagrams. Look for the power window relay and power window motor labels. Tug out the fuse and check it for damage. Check the switches for deterioration or abnormalities. You can get a new fuse or switch at an auto parts store or super center and easily replace it.

    • 2

      Get out your tool box if you've eliminated fuses and switches as the cause of the problem. Now you have to remove the door panel to get a better look at your window's power source. For the driver's side and passenger-side doors, remove the door pad and inner moisture barrier. Use an upholstery-removal tool to help pry the panel off. The rear windows require that you remove the two center channel screws at the top of the door frame and two lower bolts in the bottom of the door. Check under the weather stripping if those bolts aren't evident.

    • 3

      Lower the window until the glass bolts are visible. Use the 10mm socket wrench to remove the bolts in the large and smaller access holes. Standing at an angle inside the door, tip the glass gently toward the outside of the door. Pull it out and set it in a secure place.

    Inspect the Motor and Regulator
    • 1

      Access the regulator by removing the front channel and regulator mounting bolts. Older models have additional roller bolts.

    • 2

      Use a digital voltage meter to test regulator power before completely removing it. A reading of less than 12 means you have a wiring or switch problem. Recheck the fuses and switches. A reading of 12 means your wiring and switches are getting power to the motor, so the motor is inoperative for another reason.

    • 3

      Remove the motor and regulator. Wear protective gloves and keep your hands clear of the regulator gear spring. You can expect it to snap abruptly on removal.

    Install New Power Window Motor and Regulator
    • 1

      Use oil to grease the roller guides and sliding surfaces of the regulator after removing all the parts. Confirm that the breather pipe is in position to keep water out of your new motor.

    • 2

      Advance the new regulator gear with your gloved hand. Use the collar and mounting bolt to secure the new motor in place. Replace the front door run channel.

    • 3

      Slide the window glass back into the door. Advance the regulator with the power window control in the door until the glass mounting bolt holes line up with the access holes. Replace the window mounting bolts.

    • 4

      Test for smooth operation of the window. The window should move up and down easily and form a tight seal when closed. Tighten or loosen window mounting bolts as needed.

    • 5

      Replace the liner and door panel. Dispose of the dead motor.

    The drivers side window stoped working on my 2004 silverado the passenger side works fine


    Try the fuse. The switch may be faulty so check by removing the inner door panel and connecting a 12v battery via two wires to the motor that winds the window up and down. If it goes up and down it's probably the switch which may just need a clean on the terminals.

    2000 saturn power windows,driver window does not


    you would first have to make sure it is switch.Motors and regulators go out often. Does the drivers door switch operate passenger side ok? Can you hear any noise when switch is is up or down position?You would want to make sure all of this first. Door panel controls are easy to replace but you really want to remove panel and make sure you have good motor and window regulator.

    Rear side windows


    This may be just a case of inadvertently hitting the window lock out n th driver door window switch by mistake. Check that first. Here's some background on window operation

    Principles of Operation
    The driver power window regulator motor is controlled directly by the master window/door lock/unlock switch (and its integrated "auto down" module). Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
    The driver power window regulator motor is a reversible motor that is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
    The passenger power window regulator motor is controlled directly by the passenger power window switch and can also be controlled by the master window/door lock/unlock switch. Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
    The passenger power window regulator motor is a reversible motor, which is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
    The power rear quarter glass is also directly controlled by the master window/door lock/unlock switch. The power rear quarter glass power latches also utilize reversible motors. The power rear quarter glass power latches are operated by applying power and ground to the motor leads to open the window, and then reversing polarity on those same leads to close the window.
