From where , any switch ? driver door switch or either passenger door switch . This is a very complex system controlled by modules (microprocessors)

Class 2 and Power Door Serial Data Links
The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible.
Your best bet is to take it to the dealer or an ASE certified repair shop .

    Power Windows Operation
    The vehicle is equipped with power windows controlled by the door modules. The driver door window is controlled by the driver door module (DDM), which is located in the driver door, while the front passenger door window is controlled by the passenger door module (PDM), which is located in the front passenger door. The rear door windows are both controlled by a single, shared rear door module (RDM), which is located beneath the rear seat cushion. The DDM receives a window switch request, via the power door serial data circuit, from, either the door module wired to the passenger door window switch pressed, or from the driver door switch assembly (DDSA). The DDM first examines information from the Class 2 serial data circuit to determine if conditions are correct, i.e. ignition switch position, for window operation to be permitted. If conditions are correct, the DDM either, moves the driver door window, or, sends the request to the appropriate passenger door module to move the associated window as requested.

    The driver door window can be operated only from the driver window switch built into the DDSA while the passenger door windows can be operated from, either the appropriate window switch built into the DDSA, or, from the window switch mounted to the associated passenger door.

    The power windows may be operated whenever the vehicle is in the Retained Accessory Power (RAP) mode, or, whenever the ignition switch is turned to the Accessory or Run positions.

1995 ford futura doors wont lock

Inside the door is an electric motor that pulls the door lock down to the locked position, either the rod has come off to the door latch from the door lock motor or the motor has failed. Remove the door panel and check it for power when the button is pressed for the power locks, if it gets power then it is most likely the motor that is the problem.

Check the wires on the driver's door between the door and the post. A break in a wire will affect the passenger side.

Doorlocks dont work except from passenger side. mirrors dont work. windows dont work from anywhere

First, check all fuses to make sure that none are blown.

If the door lock switch works on the passenger side, then the drivers side door lock switch is probably faulty. Use a multi-meter to test the Drivers Side Door Lock Switch (Black and Pink/Light Green wires unlock the vehicle, and the Black and Pink/Yellow wires lock the vehicle)
If the switch is tested and found to be operating properly, you may have a faulty Body Security Module or Drivers Side Door Lock Actuator.

If neither of your Power Mirrors are working, you probably have a faulty Exterior Rear View Mirror Switch, Power Mirror Module, or blown Central Junction Box Fuse.

If none of your Power Windows are working, you probably have a faulty Accessory Delay Relay or a blown fuse in your Central Junction Box or a faulty Master Window Adjust Switch (all of the Power Window Switches feed through this Master Window Switch). If the Power Windows didn't stop working at the same time, you may have faulty Window Adjust Switches, or faulty Power Window Motors, this is very unlikely though. It would also be a good idea to inspect the wiring for any obvious damage.

Passanger side window wont go down

It won't work on either the drivers button or the passenger button? If so it's the motor, if it works on one of the buttons then it the button that won't put it down. Let me know please.
