In this case it is usually necessary to remove the interior panels of the liftgate to gain access to the linkage inside. The only problem is: removal of those panels is much more difficult with the liftgate closed. Take to a professional, or risk breaking the attachment points of your panels, and associated fasteners. I usually charge around 50 to 100 dollars to get these open, then an additional charge for further work to repair the lock, latch, or linkage.

Do This
Don't Do This

Reposition liftgate lock cylinder wave washer and adjust lock rod.
DO NOT replace the liftgate latch or actuator.


Condition
Some customers may comment on one or more of the following conditions:

• The rear liftgate glass may not lock when using the remote keyless entry (RKE), key fob transmitter or door lock switch unless the lock is pressed a second time.

• The rear liftgate or glass locks, but may be unlocked when the rear liftgate lock cylinder button is depressed.

• The rear liftgate locks but the liftgate glass may not lock.

Cause
These conditions may be caused by one or all of the following:

• The rear liftgate cylinder lock rod may be out of adjustment.





• The wave washer on the liftgate lock cylinder may be out of position with the cup side down.

• Excessive movement or slack in the lock rods at the liftgate bell crank assembly.





• The liftgate lock cylinder pawl may contact the rear liftgate glass latch when the lock cylinder button is depressed.

Correction
Important: Do Not remove the rear liftgate lock cylinder from the vehicle to perform this repair.

Reposition the rear liftgate lock cylinder wave washer and adjust the lock rod using the steps below.

Verify the customer's condition.

Open the liftgate.

Remove the upper liftgate garnish molding.

Remove the rear liftgate trim panel.

Remove the cylinder lock rod from the threaded lock rod retaining clip.

Tip
Place the tip of a screwdriver blade into the opening of the C-clip and slowly rotate the screwdriver to pry out the C-clip from the shaft. Then use needle-nose pliers to remove the C-clip.

Remove the C-clip from the rear liftgate lock cylinder push button and remove the wave washer.

Install the wave washer with the cup side up.

Position the wave washer with the curved edges of the wave spring parallel to the tabs on the lock cylinder shaft.

Important: Use needle-nose pliers to slightly squeeze the C-clip back into shape. Make sure the clip seated, you should feel a snap and hear an audible click.

Install the C-clip onto the shaft and in the slot using needle nose pliers. Then rotate the pawl several times to make sure the C-clip does not rotate. If the clip rotates then the clip is not fully seated.

Position the lock cylinder pawl to the full clockwise position.

Pull up on the cylinder lock rod to remove any slack in the bell crank.

Install the cylinder lock rod into the threaded lock rod retaining clip while removing any slack from the lock rod linkage.

Close the lock rod retainer clip.

Close the liftgate assembly.

Open the liftgate glass while keeping the liftgate closed.

Use the key fob to cycle the liftgate to the lock and unlock position while inspecting the rear liftgate pawl. The lock cylinder pawl should have clearance between the latch as shown above. If the pawl is contacting the latch, readjust the cylinder lock rod.

Verify that the customer's condition has been corrected.

Install the rear liftgate trim panel.

Install the upper liftgate garnish molding.

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.

try rolling down a window or leaving a door open, shut liftgate hard. see if it still shows liftgate ajar. on my explorer the seals in door and windows shut so tightly that it was almost impossible to get the gate closed completely with doors closed and windows up.

if this doesn't help then you might need a new switch on it.

try spraying some WD40 into the liftgate latches open and close the liftgate a few times and see if the light goes out

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
