Question about 2003 Lincoln Navigator

1 Answer

Power liftgate not working with FOB, overhead console, or when manually try to open it on 2003 Lincoln Navigator. This causes the lights to stay on in the car while driving and the suspension will not raise/lower because it thinks that the liftgate is open. I have reset it and checked the fuse. What is the likely cause? Thanks!

Sounds like the sensor/switch that detects if the door is closed or open is faulty, you can get the part from the dealership and replace it yourself or take it into the dealership or any repair shop and have them check it out and fix it.

The rear lift gate on my 2006 Lincoln Navigator will not open automatically or manually and there appears to be no way to access anything inside the door from inside or out.


POWER LIFT-GATE OPERATION - To open the optional power liftgate, push the button on the instrument panel , press on your five-button key fob (if equipped), or press and release the control located in the left rear quarter panel (Figure B). To unlatch the liftgate glass, push the button ) under the center of the license plate lamp shield, or press on your five-button key fob. Do not open the liftgate or the liftgate glass in a garage or other enclosed area with a low ceiling. Keep clear of the liftgate when operating the rear switch. To open the liftgate manually, pull the handle located on the liftgate to release the liftgate from the vehicle. The power system will take over when you release the handle. To close, make certain the rear window is closed, and then pull down the liftgate a few inches to activate power closing. Closing the gate rapidly or more than a few inches may activate the obstacle detection feature and stop the power system.------------ Also click this link for more help:--- http://technoanswers.blogspot.com/2011/05/power-liftgate-on-will-not-open-on.html ------------ This should help.Keep updated.Thanks.Helpmech.

My 2003 LIncoln Navigator liftgate is not working. I had a response that it could be the sensor/switch that senses if the liftgate is closed, but the door does not open when using the overhead console...


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.

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

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)
