Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

Circuit/System Description

The power window system will operate any time the ignition is the ACC or RUN position. The power window system will also operate whenever the body control module (BCM) is in retained accessory power (RAP) mode. The driver power window switch contains individual window switches for each of power windows. All windows may be controlled up and down from the driver power window switch. The individual passenger power window switches will only control the up and down operation of their respective power window.
Each power window contains a reversible power window motor. The direction the window travels is dependent upon the polarity of the supply voltage. By reversing polarity of the supply voltage the window motor will move up or down. Each power window motor is internally circuit breaker protected.
Battery voltage is supplied to the power window switch through the accessory voltage supply circuit. The power window switch also receives a constant ground source. The power window motor control circuits are connected to ground through the normally closed up and down contacts of the power window switch. When the power switch is placed in the down position, the power window motor down control circuit is switched to 12 volts and is applied to the down side of the power window motor. Since the other side of the power motor is connected to ground through the normally closed contacts of the up switch, the window travels down. By placing the power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.

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

  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.

My power window switch is broken. can I manually raise the window?


IF THE SWITCH IS BROKEN YOU CANNOT RAISE OR LOWER THE WINDOW you need to see why it isn't working it could be a faulty relay you will need a test light you can obtain one at any ACE hardware or auto parts jobber, remove your door panel and turn on your ignition and test the positive lead to the window motor if you are getting power do the same to your ground wire just hook your test light to a power source and check your grounds if your good there then you may suspect a faulty motor if you have no power or ground its going to be before your motor so move to your switch panel then to the relays I would most likely say do to having repaired several hundred of these over the past 35 years of doing this it fell on the window motor relay being at fault. The relay wears out or gets corroded do to the circuit getting deposits built up on it and it goes bad the best thing you can do is purchase a Chilton's manual on your year of automobile Chilton's has the best wire schematics and it makes it really easy for the do it yourselfer to fix your automobile. Pick up a 12v test light it going to cost you 5 to 10 bucks for a good one and take your time and check all your power sources and grounds. Hope I was some help good luck

Power window switch wiring schematic


Sorry, don't have one, but lookatit this way: The driver's door master switch has a hot wire to it, probably from a circuit breaker in the fuse panel, and a ground wire from master switch back into cabin to a nearby ground. Then the master switch has 2 wires to each window motor. Depending on the switch's up or down position, each wire will serve as a power signal to the motor or a ground signal back to the master switch. See? The other door switches each have a power feed wire to switch, so that switch can operate its window motor. They all work the same: Switch up or down will change the current flow to motor. The ground current flow always goes back into the master switch and then to that nearby ground.
Have I muddied it up enough for you? Well, sorry, Jim, guess you have to look at a diagram, then.

Driver's window


The wiring diagrams for your 2003 GMC Sierra power window circuits are copyrighted material and cannot be posted here. However, I can describe the driver's power window circuit to you.

Battery voltage is provided to the driver's window (master) switch via the ORANGE wire at PIn #2 on the switch connector which comes from the 25 Amp Left Window Circuit breaker located in the fuse block on the left side of the dash.

There is a logic module located inside of the master switch which controls the "Auto Down" feature for the driver's window. When the switch is operated in either the "UP" or "DOWN" position, power and ground is supplied to the window lift motor via the BROWN wire (Pin #1, Connector 2) and the DARK BLUE wire (Pin #3, Connector 2) Thease wires will switch polarity dependin on whether the switch is commanding UP or DOWN.

The schematics show that the ground circuit for the driver's window motor is supplied internally by the driver's window switch module. It is most likely grounded inside the door panel itself - the schematics do not specify. To check for ground, you can test continuity to ground on BOTH the BROWN and the BLUE wires by back-probing them with the switch electrical connector plugged in and the window control switch in the NEUTRAL position. They should both have ground.

When the switch is operated, one will remain ground while the other switches to power.

My rear window goes down but not up. the motor works. it won't roll back up.


There rear window switch works by reversing power to the window motor. In the up position it will supply power on one wire to the window motor and ground to the other. In the down position it will supply power to the wire that was previously ground and ground the wire that was previously power.

With the switch removed but still plugged in back probe all the wires with a test light. One should have power to it all the time and one should be grounded all the time. The other two wires are the ones you want to look at. With the switch in the down position. one of the two wires left should have power and the other should have ground. Since the window went down I don't suspect there will be an issue with this part of the switch. In the up position there should be power on the wire that was ground when the switch was up. There should not be power on the other wire, which I suspect there is. If the other wire has power on instead of being grounded than we know the switch is bad. If the other wire does not have power on it than the next step will be to tap the window motor with a screwdriver while holding the switch in the up position. If the motor rolls the window back up than the motor has gone bad.

Make sure the key is in the run position when you check this out.

How does the cables connect [electric windows],window will not go up or down? can you email some sort of iso to go by?


Worked on mine today. Take the door panel off and unplug the motor. rig a 2 conductor jumper wire long enough to go from battery terminal to the w. motor. hook one conductor to battery positive and other to ground.I went to strut bolt,put one conductor on each contact in the w. motor plug.then switch them. one way the window goes up the other down. if motor is good it will work, thus eliminating the motor as the problem.If motor is good then check for broken wire in space between door and jamb. this is where I left off.!!

Passenger Window Problem


On the passenger door, look for a broken wire in the door opening.

So you found power on one of the two wires. That was with holding the switch in one position, either up or down, right? Try it again, now hold the switch in the opposite position as before, now the other wire that had no power the first time should now have power. If not, probably a break in the wiring, look in the door jamb. If not a broken wire in the passenger door, it could be in the driver's door.

You see, the power is reversible to the window motors. When power goes down one wire to the motor, the other wire serves as a ground. The ground path goes back to the driver's master switch, where the ground for all the windows originate. Ground wire from master switch carries power to ground somewhere inside the cabin. Since other windows work, your ground is good. but the pass. window is, or seems to be missing a wire. Check by looking for power on both wires, but the window switch has to be opposite from the first time for the second wire to have power. Only if both show power is the wiring good, but they wont both show power at the same time-the switch has to be in right position to show power.
I hope this is clear, post back if you don't understand.

Oh yes, use the ohmmeter function of your multi-meter to check the wires' integrity. Just don't have any power on any of the wires you are checking, but check between the pass. door and the driver's master. Check both wires that go to the passenger window. That should tell you if you have a break in the wiring.
