If the door motor is 12 volts there will not be much of a problem. It will require someone with electrical knowledge that can wire in a relay so that when the power is lost the relay allows the battery to cut in and run the system

Diagnosing rear windows not working on a 02 Bonneville


Power Windows Operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door power window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally on its associated door. The driver door power window can only be operated from the driver door window switch built into the driver door switch assembly (DDSA).
When the driver door module (DDM) receives a window switch request from the DDSA, the DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation to occur. If the status information is correct, the DDM, either supplies power and ground to its associated window motor, or, if the request is for one of the passenger windows, sends a command via the power door serial data circuit to the passenger door module (PDM, LRDM, or RRDM) controlling the window. The passenger door module (PDM, LRDM, or RRDM) controlling the window then supplies power and ground to its associated window motor to move the window as requested.
When one of the local window switches mounted on one of the passenger doors is operated, the associated door module examines the request and checks to see if there are any messages from the DDM prohibiting the movement. If conditions are correct, and no prohibitive messages have been received from the DDM, the associated door module then supplies power and ground to its associated window motor to move the window as requested.

Do you know about computer controlled windows and door lock systems ?

Each door module has its own battery positive voltage supply circuit to use for power window operation, but they are all fed by the same 30 amp power window circuit breaker located in the rear fuse block. Each door module also has a seperate ground circuit to use for power window operation. These circuits are in the same dedicated connector as the window motor control circuits of each door module and are used exclusively for window motor operation.
Each door module also has a battery positive voltage circuit and a ground circuit that are used to power up the module ,as well as, to control mirror and door lock functions. Battery positive voltage to the DDM is supplied through the DRVMDL 10 amp fuse located in the rear fuse block. Battery positive voltage to the PDM is supplied by the PASS MDL 10 amp fuse located in the rear fuse block. Battery positive voltage to both the LRDM and RRDM is supplied by the RRDR MDL fuse located in the rear fuse block. Ground for the DDM is provided through a ground circuit to G200. Ground for the PDM is provided through a ground circuit to G201. Ground for the LRDM is provided through a ground circuit to G302. Ground for the RRDM is provided through a ground circuit to G301.
Window Motors
Each door module supplies battery positive voltage and ground, through the window motor control circuits, to its associated window motor. The window motors are reversible. The direction the window moves depends on which motor control circuit the battery positive voltage is applied to, and which motor control circuit the ground is applied to.To move the window in the Up direction, the module applies battery positive voltage to the window motor Up control circuit, and ground to the window motor Down control circuit. When a window movement in the opposite direction is needed, the module reverses the polarity and supplies power and ground to the opposite circuits to move the window in the reverse direction.

How do I repair the four wheel drive on a 1999 Ford Ranger XLT?


It depends on what is wrong , is the 4x4 light flashing ? Are you aware of the complexity of the 4x4 system ? Has a electronic control module , has the ability to set an store DTC'S - diagnostic trouble codes !
Transfer Case The four wheel drive system is an electronic shift 4X4 system that allows the operator to choose between three different modes. The operator can switch 4X4 HIGH modes at any speed. To engage or disengage 4X4 LOW the vehicle speed must be less than 5 kph (3 mph), the brake depressed, and the transmission must be in NEUTRAL.
The shift motor sense plate, an integral part of the electronic shift motor, informs the generic electronic module (GEM) of the transfer case shift motor and contact plates A, B, C and D position.
The digital transmission range (TR) sensor is located on the LH side of the transmission, and informs the GEM when the transmission is in the NEUTRAL position.
The electronic shift motor is mounted externally at the rear of the transfer case. It drives a rotary cam which moves the mode fork and range fork within the transfer case between the 4X4 HIGH, 4X4 LOW and 2WD range positions.
When the GEM verifies the completion of the transfer case shift from 2WD to 4X4 HIGH (reading the contact plate positions), the GEM will then energize both pulse vacuum hublock (PVH) solenoids (supplying ground for 45 seconds). The PVH solenoid will allow a HIGH flow of intake manifold vacuum to the "wheel end hublocks", engaging the wheel end hubs to the front differential and transfer case to achieve four wheel drive.
Here are just a few DTC'S the system can set an store in the module !

2002 f150 4wd drive not not working,


Transfer Case - Electronic Shift on the Fly (ESOF) Features A rotary switch allows the vehicle operator to choose between 2WD, 4H, and 4L modes of 4x4 operation.
The generic electronic module (GEM) controls the operation of the 4x4 system.
The output shaft speed (OSS), mounted in the rear of the transfer case, informs the GEM of the vehicle speed.
The shift motor sense plate, an integral part of the electronic shift motor, informs the GEM to the positions of the transfer case (go to Table 4).
The transmission range sensor is located on the LH side of the transmission; this sensor informs the GEM when the transmission is in the NEUTRAL position.
The electronic shift motor, mounted externally at the rear of the transfer case, drives a rotary cam which moves the mode fork and range fork within the transfer case to select between the 2WD, 4H, and 4L positions.
The 4x4/4x2 vacuum solenoids are attached to the upper RH side of the engine compartment, and alternately route vacuum to the vacuum motor which engages/disengages the center axle disconnect collar in the front axle assembly.
The 4x4 shift motor relay is a module containing two relays. Under the control of the GEM, the 4x4 shift motor relay shifts the transfer case shift motor between the 2WD, 4H, and 4L modes.
The transfer case clutch relay is an electromechanical relay used to activate the transfer case clutch within the transfer case.

99 ford f150 4wd won't engage, clicks but does not engage


Without knowing how the 4X4 works you don't have much chance of finding the problem , (tapping on stuff ) ? There is an electronic control module that makes this system work . Could have DTC'S - diagnostic trouble code's stored in the (GEM)
Transfer Case -Electronic Shift on the Fly (ESOF) Operation The electronic shift on the fly (ESOF) system is an electronic shift 4x4 system that allows the operator to choose between two different 4x4 modes as well as 2-wheel drive. The operator can switch between 2WD and 4H mode at speeds up to 88 km/h (55 mph). To engage or disengage 4L range, the vehicle speed must be less than 5 km/h (3 mph), the brake pedal depressed, and the transmission must be in NEUTRAL.
The transfer case is equipped with an electromagnetic clutch which is located inside the case. This clutch is used to spin up the front driveline when shifting from 2WD to 4H mode at speed. When the control switch on the instrument panel is turned, the generic electronic module (GEM) recognizes that a shift has been requested and activates the electromagnetic clutch and the relays which power the transfer case shift motor. When the shift motor reaches the desired position, as determined by the contact plate position inputs to the GEM, power to the shift relays and motors will be removed. When the transfer case front and rear output shafts are synchronized, the spring loaded lockup collar mechanically engages the mainshaft hub to the drive sprocket. Finally, the front axle collar is engaged and the electromagnetic clutch is deactivated.
Shifts between 2WD and 4H can be made at any speed up to 88 km/h (55 mph). Listed below are the inputs and outputs needed by the GEM to execute a change between any of these modes.
Feature Inputs:
  • 4WD mode switch (various resistances; go to Table 1).
  • Contact plate position inputs A, B, C, D (grounded when closed, open circuit when open; go to Table 4).
Feature Outputs:
  • 4x4 shift motor relay outputs (go to Table 2).
  • Transfer case clutch relay (grounded when relay is activated, open circuit when relay is deactivated).
  • 4x2/4x4 vacuum solenoid (grounded when activated, open circuit when deactivated).
  • Cluster indicators (ground when activated, open circuit when deactivated).
When shifting into or out of 4L, the GEM requires that the vehicle speed be less than 5 km/h (3 mph), the brake is applied, and the transmission is in NEUTRAL.

Feature Inputs:
  • 4WD Mode Switch (various resistances; go to Table 1).
  • Contact Plate Position Inputs A, B, C, D (grounded when closed, open circuit when open; go to Table 4).
  • Output Speed Shaft (OSS) Sensor (Sinusoid Signal: 0.7V-20V, 2.2 Hz/mph).
  • Brake Input (battery voltage when brake is depressed, open circuit when not activated).
  • Transmission Range Sensor (grounded when transmission is in NEUTRAL, open circuit otherwise).
  • Start/Clutch Depressed Input (go to Table 3).
Feature Outputs:
  • 4x4 Shift Motor Relay Outputs (go to Table 2).

cause of the failure
1.the wire going to the motor may be chopped off.
2.the junction box connecting the wires may be damaged.
3.fuse may be blown out.
4.motor itsef damaged.

so please check weather power is coming to the motor using multi meter. if the power is not coming to it then the problem is with the wires. if the power is coming to it then problem is with the motor.

please vote me if my answer was useful to you.

Ford 2005 4x4 problem.


2-Speed Torque-On-Demand (TOD) Operation
The automatic 4-wheel drive (A4WD) system is a 2-speed torque-on-demand (TOD) operation that utilizes the following components:
  • Transfer case
  • 4-wheel drive (4WD) control module (integral to the powertrain control module [PCM])
  • Mode select switch (MSS)
  • Gearmotor encoder assembly (part of the transfer case shift motor)
  • Transfer case shift motor
  • Shift motor sense plate (part of the gearmotor encoder assembly)
Principles of Operation
Transfer Case Shift Motor The externally mounted transfer case shift motor, located at the rear of the transfer case, turns the shift cam assembly. As the shift cam assembly turns, it positions the reduction shift fork for desired transfer case operation. An integral position sensor in the shift motor provides shift motor position information to the 4WD control module.
Mode Select Switch (MSS) The push button MSS, mounted on the instrument panel, allows the operator to select the 4x4 Auto, 4x4 High, and 4x4 Low transfer case operating modes. The indicator light, on the instrument cluster push button, will illuminate only when the 4x4 Low position is engaged.
