The liftgate actuator and remote control are in the liftgate.
The module is in the left rear quarter trim panel.

-----------------------------------------------------------------------------------------

Principles of Operation
The power liftgate is controlled by the power liftgate module.
The power liftgate module receives inputs from:
  • glass position switch (determines the ajar status of the liftgate glass).
  • forkbolt switch (determines the primary position of the latch).
  • detent switch (determines the secondary position of the latch).
  • home switch (determines the power cinch status).
  • power liftgate control switch (activates the power liftgate from the interior of vehicle).
  • pinch strip switches (determines if an obstacle is detected between the pinch strip and liftgate).
  • instrument cluster module (activates and sets the options for the power liftgate).
  • optical sensor (determines the direction, travel speed and obstacle detection of the liftgate).
  • UBP serial communication link.
The power liftgate module sends outputs to:
  • liftgate motors.
  • power cinching latch system.
  • liftgate chime module.
  • body security module
------------------------------------------------------------------------------------

The liftgate consists of the following components:
  • liftgate window glass latch
  • door lock actuator (power liftgate only)
  • liftgate latch
  • liftgate handle
  • liftgate latch remote control (power liftgate only)
  • liftgate ajar switch
  • chime module (power liftgate only)

06 Lincoln Navigator liftgate opens okay but need help to close why?


Power Liftgate
The power liftgate feature will allow the customer to automatically OPEN or CLOSE the liftgate by activating the interior open/close switch, the remote keyless entry transmitter or by manually initiating liftgate movement. The power liftgate uses a power cinch system to latch the liftgate.
The power liftgate system consists of the following:
  • Power liftgate control switch (located in the overhead console)
  • Power liftgate motors (located in the rear headliner area)
  • Optical sensor and power liftgate encoder wheel (located in the left power liftgate motor assembly)
  • Pinch strip switches (located on the body by the liftgate)
  • Home position switch (located on the cinch actuator)
  • Forkbolt switch (located on the cinching latch assembly)
  • Detent switch (located on the cinching latch assembly)
  • Liftgate close chime module (located in a unit external from the power liftgate module)
  • There are a lot of electrical switches an motors
  • Visual Inspection Chart Mechanical Electrical
    • Power liftgate motors
    • Power cinching latch and linkage
    • Power liftgate pinch strip switches
    • Liftgate and liftgate hinges
    • Liftgate assist cylinders
    • Liftgate strikers
    • Exterior release handle and linkage
    • Liftgate weatherstrip
    • Liftgate alignment to body and striker
    • Central junction box (CJB) fuse:
      • 5 (7.5A)
      • 105 (30A)
    • Power liftgate control switch
    • Wiring harness

2004 lincoln navigator ,doors will not open rear hatch will not unlock


The door locks are controlled by the vehicle security module (VSM). It gets power from fuses 30, 5, 6, and 40 in the central junction box (CJB). You say you checked these and all are OK. Therefore the problem must be in the door lock actuators, the door lock relays, or the door lock switches. I doubt that all of these are defective, so the VSM may be defective.

The liftgate is controlled by the power liftgate module (PLM), althogh the motor in the liftgate glass actuator is controlled by the VSM. The PLM gets power from fuses 105 and 5 in the CJB. If the PLM is assumed to be OK, the source of the problem could be the liftgate unlatch motor, the liftgate cinching motor, the L/R liftgate obstacle detection strips, the liftgate home position switch, the liftgate fork bolt/detent switch. or the power liftgate open/close switch

The rear suspension is dropping and it stays stuck, is there a motor that needs to be replaced or is this an electrical problem? The automatic liftgate stopped working and the dash indicates that the...


This liftgate issue is the reason your Air suspension is not working. The ride height is determined after the tailgate and the doors are shut. The suspension is designed to keep the cargo loading height low to make it easy to load.

You need to find the switch in the liftgate area that is not sending the signal that the liftgate is closed. It can be a plunger type pin like in the doorjams or a extended plastic arch that pivots when the lid is shut. Check around the hinges of the liftgate.

If you find and press the pin switch and the dash indicator does not go off, you may have to remove the switch and cross the wires to get a response. You may have lost a grounded connection from the switch. The Air suspension uses Vent solenoids to release the air from the system. Since the dash shows the problem, most likely the solenoid will work once it gets the signal from the liftgate. Right now it is being told to deflate and vent the air.

I hope this is helpful to you. If you can not find a contact switch ask a Lincoln partsman for a Diagram of the location and the price and availability of the switch.

Wheres the liftgate switch located?


If your Nav is the same as my 03 windstar and I'm not sure it is, mine are located one on each side about 3/4 ways down inside the liftgate. I took the interior panel off and was able to locate them. I then cut the wires to the switches and tied the wires together to each switch. Of course this makes the car think the gate is closed all of the time. Even when its open. That was fine because i don't know about your Nav but my interior lights would not work nor the doors would not lock when you put ity in gear. My wife says is this safe to do? Like daa if you don't know that your liftgate is open and you need a idiot light to tell you that. come on. Good luck.

check relay and fuses,make sure that automatic liftgate is on. You will have to to the command center and go through the defaults and make sure that the system is on. if you are not comfortable doing that, disconnect battery for approximate ten minutes, this will reset the system defaults.
