It sounds like the wire harness has a break in the wire from the body frame to the door frame at the door hinge. You'll see a rubber tube that runs from the body frame to the door and the wire harness is in there, as the door is open the wires make contact and as the door is close the wire breaks causing your window to react the way they do. You can by the wire harness or you can repair the damaged wire to your window you self by taking the rubber tube off one side, door or body to get to the wires inside and find which wire is the one for the window and repair it. Good luck and hope this helps. Keep me posted. be glad to help.

Maybe its jammed, or the rail of the motor or the manual handle is moved out of the place. or the rail of the window is damage(out of place) to make work.

I need the wiring schematics for driver door panel and all switches in a 2003 Chevy Tahoe. My window won't go down on that side and I'm sure I have a short somewhere because my switch works with all other...


You don't know what your getting into , The door switches have electronic control modules incorporated ,DDM- Driver door module an PDM passenger door module .
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)


The DDM contains four power window switches which are integral components. Closing any of the normally open, rocker type switches provides the DDM with a request for power window operation. The switches for the two front windows have three positions UP, Down and Express Down, while the switches for the rear windows have only two positions, UP and Down. Each of these switches and their positions is a direct input into the DDM. Upon receiving a request for power window operation, the DDM, transmits a Class 2 message indicating the switch and it's changed position.
The PDM contains a single power window switch that is an integral component. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation. The switch for the front passenger window has two positions Up and Down. Each of these switch positions is a direct input to the PDM.
The two rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows. However the BCM, upon receiving a Class 2 message from the DDM, can control the set of relays which will activate the rear window motors.
You need a scan tool to diagnose these systems
Power Window Inoperative - Driver Door

1

Did you perform the Door Systems Diagnostic System Check?
Go to Step 2
Go to Diagnostic System Check - Door Systems

2

Operate the driver power window in the UP and DOWN directions.
Does the driver power window operate properly?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3

3

  1. Install a scan tool.
  2. Monitor the driver window status data parameter in the driver door inputs list.
Does the driver window status data parameter display an active state?
Go to Step 11
Go to Step 4

4

  1. Monitor the driver window status data parameter in the driver door module inputs list.
  2. Activate the driver power window switch in the up and down positions.
Does the driver window status data parameter change accordingly?
Go to Step 5
The data link connector (DLC) allows a scan tool to communicate with the class 2 serial data line. The serial data line is the means by which the microprocessor-controlled modules in the vehicle communicate with each other. Once the scan tool is connected to the class 2 serial data line through the DLC, the scan tool can be used to monitor each module for diagnostic purposes and to check for diagnostic trouble codes (DTCs). Class 2 serial data is transmitted on a single wire at an average of 10.4 kbps.

Windows on passenger side front and rear won't work, up or down.


He could have been more helpful and explained it's likely some broken wires in the door openings. Check carefully the wire harness in the front driver's door and in the passenger front door, where wires get stressed the most when opening and closing doors. The driver's window switch is the master switch for all windows, check there and the other doors openings for broken wires. Splice back together any broken wires you find and recheck windows. Hope you find it. If not there, but somewhere else in the harness, you would probably need professional help to find it.

Outside handle on 1997 Toyota Avalon will not open door


Since you can get the door open, half the battle is already won. Yes, open the door, pull the interior door panel and take a look around. Watch inside with a flashlight (towards the rear of the door) as you roll the window down to see if you can see what it's snagged on.

1999 Dodge Durango driver side window does not roll up nor down.


Remove the door panel and find the window motor Unplug it and using a separate car battery run cables directly to the window motor When you switch the polarity the motor will either bring the window up or down or if noting happened change the window motor and window regulator assembly.

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.
