92 F150 power window and locks

Look at the end of the dash and between the drivers side door for a second fuse panel. I think everything you mention works on one data bus. You can remove the button pad on the drivers door. Since it gets used all th3 time i# might have gone bad messing up the works.

How do you know they need to be replaced ? The switches incorporate a electronic module . Driver door module .
Power Window System Components
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)

Power Window System Controls
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 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.


The door locks operate the same way .

Door Lock System Components
The power door lock system consists of the following components:
• The driver door module (DDM)
• The passenger door module (PDM)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock switch
• The door lock relay
• The door unlock relay
• The liftgate lock relay--utility vehicles with liftgate only
• The reversible door lock actuators in each of the doors and liftgate
• LOCKS 20A fuse (rear lock/unlock relay supply voltage)
• ECC 10A fuse (liftgate lock relay supply voltage)


What's not working ? Windows , power locks ?
Hooking up a professional type scan tool ,not a code reader . Code reader can not read codes in the BCM or door modules . Do you know what a DTC is ? diagnostic trouble code >All these can set for door electronic problems .
DTC B1023
DTC B1544, B1600, or B1605
DTC B1580, B1590, B1610, or B1620
DTC B1640 or B1645
DTC B1722
DTC B3808
DTC B3809
DTC B3819
DTC B3820
DTC B3821
DTC B3822
DTC B3823
DTC B3824

Did you check power an grounds at the driver door switch ? Before changing the switch ? How about fuse's ? You could go to you tube an check out videos on power windows an door lock trouble shooting . Basic electrical trouble shooting etc.... Go to www.bbbind.com/ for free wiring diagrams to trouble shoot the circuits .

I ran into a problem like that on a ford focus , the alternator was the problem . Test or have the charging system tested . Check for DTC'S - diagnostic trouble code's .

door and window switches most likely..

Might want to check the doors with the problem windows for a broken wire from the door to the door jam.

The window lock switch is a single circuit to all the other windows, so if there was a problem with it, none of the window controls would work ( but the driver's side would still operate them ).

The other place to check for a broken wire is the driver's side door to a-pillar harness. The circuits for the other windows run through the driver's side switch. Could be a wire in the driver's side door harness.

The other item could be the driver's side switch, the contacts will get carbon built up on them, and the windows will not operate anymore.
This is what mine looked like when the driver's side window stopped working ( lower left hand corner of the picture is the driver's side window switch, note the carbon build up on the contacts )


I would start with checking for broken wires, by metering the window switch for power.

The back passenger's window switch should be getting power & ground on the white w/ yellow stripe wire and the tan w/ light blue stripe wire.
in the "at rest" position on the driver's side switch, these are supplying ground to the power window, and power is being applied to the other side of the motor ( depending on direction of travel ).

If the power window itself still work fine, and the illumination on the driver's side door lock still work, then the LEDs behind the switch are the issue ( usually bad solder joints ).
If you are talking about all doors other than the driver's side, do you have the window lock on ? The lights on the switch turn off when the driver's side window lock is enabled.

are the lock motors bad?the rubber around them dry up and allow water in them.

If the lock is trying to move, like you hear it but nothing really happens, replace the door lock actuator. i believe the windows are on the same fuse. Try removing the interior door trim and tap on the window motor lightly with a small hammer while holding the switch. If the window moves, replace the motor. If not, check for power and ground at the connector. If you have power and ground (which switch when going up then down) then replace the motor. If you dont, repair the circuit.

Check your window lockout switch, it will either be on the drivers door or the console. It's there to keep kids from playing with power windows. Check your fuses inside the cab and under the hood for window fuses. The door lock problem would be a defect inside the drivers door since both locks are wired together. If this is sometime that just happened I would suggest you contact your insurance company to see about attempted theft damage. Someone could have slipped in a SLIMJIM and messed the wires up in the drivers door. A body shop could tell once the door panel is removed.
