First off ,don't suspect anything . Learing what all is involved in the power window system would be the first step . And then testing , not having someone guess .

Power Window System Components
The power window system consists of the following components:
• Driver Door Switch (DDS) (RPO A31/AN3/DL3)
• Driver window switch (RPO A31 W/O AN3, DL3)
• Passenger Door Switch (PDS) (RPO A31/AN3/DL3)
• Passenger window switch (RPO A31 W/O AN3, DL3)
• Body Control Module (BCM) (RPO A31/AN3/DL3)
• Rear door power window switches
• Power window motors in each of the doors (circuit breaker protected)
• LT DRS Circuit Breaker
• RT DOORS Circuit Breaker
• Sliding Rear Window Switch
• PWR REAR WNDW Circuit Breaker
• Sliding Rear Window Relays
• Sliding Rear Window Motor

Power Window System Controls (RPO A31/AN3/DL3)
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The driver master control switches are integrated into the DDS. When a power window switch is activated in the up or down positions the DDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the DDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist and during window motor operation the DDS continues to monitor the motor current to verify proper window motor operation.
The DDS controls the passenger window through a GMLAN message to the PDS. When a power window switch is activated in the up or down positions the PDS supplies power and ground to the window motor control circuits to drive the window motor in the required direction. Prior to activating a power window motor the PDS will supply the control circuit with a low current bias voltage in order to determine that a short to ground condition does not exist, and during window motor operation the PDS continues to monitor the motor current to verify proper window motor operation. (Scan tool support is available for this system)

Rear Power Window Lockout Operation (RPO A31/AN3/DL3)
The BCM monitors the window lockout command from the DDS. When the rear window switch operation is authorized, the BCM sends a signal to the rear window switches allowing for normal window operation from the rear switches. If the rear window lockout function is commanded, the BCM signal voltage drops approximately 5 volts which disables the rear window switches and the rear windows will only operate when the BCM receives a command from the driver master control. The lockout feature will remain in effect until the ignition switch is cycled or the driver enables the rear windows by pressing the rear window lockout switch again.

Taking the vehicle to a qualified repair shop would be your best bet . Checking for codes in the BCM - body control module
DTC B3819, B3820, B3822, or B3823
DTC B3819 00: Left Rear Window Up Control Circuit
DTC B3820 00: Left Rear Window Down Control Circuit
DTC B3822 00: Right Rear Window Up Control Circuit
DTC B3823 00: Right Rear Window Down Control Circuit

You could check for damaged wires inside the door flex (rubber boot from the body) to the driver door .

The window master switch has a lock out on it, make sure it's off otherwise suspect the master switch in the drivers door.

SOURCE: power windows

I think on that year there is a safety switch on the inside of rear door jam so the children cannot roll windows down and fall out. It should be on the back door when you open the door look for a caution sticker that says child protection switch, I sure hope thats the problem And if so Great If not get back to me I can look up where the power relay is for rear windows. Ok Take care, Bear001

This would more than likely NOT be a sensor problem.

In replacing the hinges you more than likely disrupted the wires that run from the cab into the door, causing a ground, pinching a wire or in some way causing no power to get through one of the wires. There is a rubber boot that runs between the door and the cab, pull it back and have someone hold the button in the down position. Then wiggle the wires until the window moves. That truck will have defog mirrors on it more than likeley so there will be plenty of wires to wiggle. When you find the problem wire simply cut the problem area, replace it with an end to end connector (**** connector) and seal it with silicone. If it is not one of the wires, you more than likely had a wire come off inside the door. (depends on how much you horsed it when you were changing those hinges) Thats where i'd start.

Best Of Luck!

SOURCE: radio, power steering, power widows all

I won't say 100% that this is your problem, but it is a common problem on 97-ish, through at least 01 Taurus models and affects the key-on accessories and it's easy to check so it's where I'd start. Take the driver's side front wheel off and then remove the splash shield from the wheel well. towards the back of the well is a plastic track that bundles the wires up and they do a switch-back there at the end closest to the driver's seat. The wires like to rub through there causing the engine to not start, or die when put in reverse but run normally in park and key-on accessories (radio, windows, etc) to not work also sometimes better in park. That is where I'd start.

I have a 2008 chevy silverado crew cab and one of the door locks doesn't move


This is a very common problem on all chevy trucks for this year. The door lock solenoids are integrated into the door latch assembly, and are notoriously weak. They will work fine sometimes, others they just seem to barely move or not at all. You will need to replaced the door lock / latch assembly for the affected door.

2007 Dodge Dakota power widow intermittent


Find yourself wiring diagrams an test the electrical circuits . Do you know how to use a DVOM - digital volt ohm meter ? How to take the door panels off an check power an ground circuits to the switches ? If not , your best bet would be to take it to a qualified repair shop. You probably don't know what serial data network is ?
The B+ power for the door locks & power windows comes from a circuit breaker ,not a fuse . Circuit breakers very really fail .
You probably have broken wire inside the rubber flex boot from the body to the driver door .
