Power windows do not go or down - 1996 Ford Crown Victoria

Replace the master switch assembly.

Rear Passenger Power Window Operation
The rear passenger power window switches receive battery voltage through the window lockout control circuit if the window lockout function is disabled. Ground for the rear passenger power window motors is supplied through normally closed up and down contacts of both the rear passenger power window switches and the driver power window switch. When the either rear passenger power window 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 rear passenger power window motor. Since the other side of the rear passenger power motor is connected to ground through the normally closed up contacts of both the rear passenger and driver power window switches, the window travels down. By placing the rear passenger power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.
The rear passenger power windows can also be controlled from the driver power window switch.

Did you try pushing the lock out switch on the drivers master switch ?

Are all windows not working ? Two separate circuit breakers left & right . Both in rear fuse box . Fuse Block - Rear Beneath the left rear seat
Check for broken wires inside the rubber boot from body to doors.
Do you know about electronic control modules ?
The power window system consists of the following components:
?€¢
Driver door module (DDM)

?€¢
Passenger door module (PDM)

?€¢
Body control module (BCM)

?€¢
LR power window switch

?€¢
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 rear window)

?€¢
RT DOOR CB 25A (System power for right rear window)

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 DDM contains 4 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 2 front windows have 3 positions Up, Down and Express Down, while the switches for the rear windows have only 2 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 2 positions Up and Down. Each of these switch positions is a direct input to the PDM.
The 2 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.

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.

The only wiring schematic I could find for your car is for the 2000 Buick Regal, but I hope this helps,
since it gave me a reason why starting a car would cause the driver's power window to
go down, and no other window in the car - it has a special circuit component
(the "Express Down Module").

Its possible that the Express Down Module in the power window switch circuit has failed. This
module latches the "Express Down" switch in the "made" state until released by the "Express
Down Module." If the Express Down Module is latching the Express Down switch when it
shouldn't (at power-up) instead of when it should (at the window "down" limit), then the driver's
window would lower when the driver starts the car. The way to tell if this is the problem is to
note how fast the driver's windows goes down - if it goes down ALL THE WAY, then you know
that the "Express Down" circuit is involved (and therefore suspect the Express Down Module).
If the driver's window only lowers part of the way, then the Express Down circuit is exonerated.
See the various components of the driver's power window circuitry in the
2000 Buick Regal power window circuit schematic below.

If they sound like they are trying to do something it's not the lock out switch . But to be sure pulling out the switch an testing for B+ voltage to and from the switch . Plus pull the other door switches to see if they have B+ voltage and good grounds would be the thing to do.. If you don't know how to check automotive electrical circuits your best bet , take it to a qualified repair shop .
Passenger Power Window Operation
The passenger power window switches incorporate window up and down relays. The relay coil feed and supply sides are powered through the RAP fuse supply voltage circuit. The normally closed contacts of each relay is connected to ground. The load side of each of the relays are connected to either side of the power window motor through the power window up and down circuits. The up and down relay control circuits are connected to the normally closed contacts of the passenger window switch. These contacts are wired in series with the power window master switch, through the power window master switch up and down signal circuits and then to ground when the power window master is placed in the up or down position. This allows for the up and down operation of the passenger power window from the power window master switch. The center pole of the passenger power window switch is also connected to ground and will energize the relay when placed in the up or down position.

Driver Power Window Operation
The driver power window is unique from the passenger power windows in that it does not use window up and down relays. The driver power window is operated directly from the power window switch.
The normally closed contacts of the switch are connected to ground and the center pole is connected to the RAP fuse supply voltage circuit. By placing the left power window switch in the down position, voltage is applied to the power window motor left front down circuit and to the power window motor. The other side of the power window motor is connected to ground through the normally closed contacts of the left power window switch through the power window motor left front up circuit and drives the window down.
By placing the left power window switch in the up position the polarity of the motor is reversed and the motor drives the window up.

Has circuit breaker for B+ power
• PWR WDO CB 25A (fuse block) (System power for left and right windows 2-door vehicles. System power for LF and LR windows 4-door vehicles)
• PWR WDO CB 25A (IP wiring harness junction block) (System power for RF and RR windows 4-door vehicles)
