I have a 2005 Navigator. Sometimes the liftgate works correctly. Other times it will close via remote, then immediately reopen. Sometimes, I must stop it manually, then push it closed by hand so I can drive away. It will also open once in the closed position on occasion, when I close a door on the vehicle. I notice that it usually does not fully latch when closed manually.

I just bought an equinox 2005 LS and I dont know how to lock the rear door.

To unlock the liftgate, press the unlock button on the Remote Keyless Entry (RKE) transmitter twice or use the power door lock switch.
To lock the liftgate, press the lock button on the RKE transmitter or use the power door lock switch. The liftgate does not have a key lock cylinder.
To open the liftgate, pull up on the handle located in the center of the liftgate.
When closing the liftgate, use the molded handles to pull the liftgate down. Push the liftgate closed until it latches.

How can i Open and Close my Lincoln Navigator 2005 Door locks and slide gate by using door pin code

As lomg as you have the factory code the procedures are as follows: To unluck the drivers side dorr, simple push in the 5 digit code. If you want to unluck the other doors & liftgate, after you push in the 5 digit code and the drivers door unlocks push the 3/4 button within 5 seconds and if you want you can open the liftgate window by pushing the 5/6 button within 5 seconds. If you want to lock all doors and liftgate, after the drivers side door is closed you can push the 7/8 & 9/0 button at the same time and all the doors & liftgate will lock. As far as the sliding door, no the keypad cannot be used for that. the only other function I believe you can do with the keypad is to activate or deactivate the autolock & you can also store a personal 5 digit code as well. This should be in your owners manual if you have one. If you do not and would like a copy, you can email me at [email protected] with your make, model and year and I will be happy to email you a copy. I hope this helps and good luck.

Linclyn navigator 2007- the rear liftgate was manually shut without using the button control. Now the liftgate will not open. One dealer suggested depressing the lock/unlock control several times to...

can you open it manually? try leaving it open and disconnect the battery and wait a couple minutes before plugging it in. after you plug it in, try to close it with the button or remote. seems like the system doesn't know at what position the door is is, so it won't open it. give it a try.

2003 where is the modules for the liftgate in a 2003 lincoln Nav

tascafordparts.com for discount.

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

SECTION 501-03: Body Closures 2003 Expedition/Navigator Workshop Manual
REMOVAL AND INSTALLATION Power Liftgate Module Removal and Installation
NOTE: Prior to removal of the power liftgate module, it is necessary to upload module configuration information to a diagnostic tool. This information needs to be downloaded into the new power liftgate module once installed. For additional information, refer to Section 418-01 .

Remove the rear quarter trim panel. For additional information, refer to Section 501-05 .

Remove the power liftgate module.
1. Disconnect the electrical connectors.
1. Remove the bolts.

NOTE: Once the new power liftgate module is installed, it is necessary to download the module configuration information from the diagnostic tool into the new power liftgate module. For additional information, refer to Section 418-01 .

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

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)

Electronic's , aren't they great ? There is a control module (power lift gate module ) Switch (sensor) inputs to the module . Lift gate obstacle detection strip right and left , liftgate cinching motor ,liftgate unlatch motor .Liftgate drive motor assemblys left and right . Probably a bad switch feeding bad voltage signal to the control module ! Like one of the obstacle detection sensors maybe. Could possibly have DTC'S - diagnostic trouble codes stored in the control module. Your best bet maybe to have the dealer run diagnostic's on it , check for codes . Need a factory or professional type diagnostic tool to do this. I would say you mite be able to check the sensor inputs to the module , don't know what or how much voltage > Some of these circuit's are a five volt signal from the module . Ohm check the obstacle detection sensor ? I still think best thing would have it checked for DTC'S . Almost forgot about the thing opening when you close another door , All the modules on the vehicle are connected on what is call a serial data network . Doors have modules inside as well .could be commanding that door open some how.
If you would like to see what your up against , here is a web site for free wiring diagrams http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size. Under system click on body & accessories , then under subsystem click on power liftgate. Click the search button ,then the blue link. The second diagram down starts liftgate diagrams . 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.

SOURCE: Liftgate will not stay open. When you push button

HilAry when the lift gate goes to the open position does it make a grinding noise when it reaches the fully opened position and then closes, If so the gear driven assembly may have had a tooth broken on one of the gears and has striped out causing the gate to fall back down. If this is not the case meaning there is no grinding noises coming from the gate then you have a ecm module that operates the functions of the gear driven unit telling it when to stop and go down. If this is the problem you might want to take it to the dealership to program the new unit. I hope this helps.
