Sticking Liftgate

[pjsockett]

I have a 2012 SEL with a power liftgate. On Saturday, I noticed it was creaking a bit when I opened it. Yesterday it went about half way and stopped, if I push the button again it will finish going up. Today, it goes about 2 inches at a time. It seems to be the actual power power actuator not the hydraulics. Is there anything that I can do to lubricate that or does it have to be replaced?

Condition

The power liftgate stops during power open operation

Possible Sources

1. The vehicle was started or taken out of PARK during a power open operation
2. Mechanical binding

Action

1. INITIALIZE the power liftgate. REFER to Power Liftgate Initialization in this section. If condition still exists, manually CLOSE the liftgate to the primary latch position and OPEN the liftgate, using the exterior handle or liftgate control switch with the vehicle in PARK and the ignition in the ON position.

2. If mechanical binding does exist, REFER to Liftgate in this section.

 

Power Liftgate Initialization
NOTE: The power liftgate may not operate correctly under the following conditions:

* A low voltage or dead battery
* A disconnected battery
* Repairs/adjustments have been made to the power liftgate rod, power liftgate motor, liftgate hinges or liftgate striker

If any of these conditions has occurred, the power liftgate must be reinitialized.

1. NOTE: Battery power must be removed from the Liftgate/Trunk Module (LTM) for 20 seconds before the LTM will enter the initialization mode. ***

 

Disconnect the battery or remove the LTM fuse(s).

2. Wait 20 seconds and reconnect the battery or reinstall the LTM fuse(s).

3. If liftgate is not already in the fully closed position, manually close and fully latch the power liftgate.

4. NOTE: Make sure the power liftgate system is turned ON in the message center before performing this step.

 

NOTE: If the power liftgate does not open during this step, refer to the Symptom Chart to diagnose the inoperative power liftgate.

 

Power open the power liftgate by using the key fob or control switch.

5. Once the power liftgate is fully open, close the power liftgate by using the key fob or control switch.

 

 

*** I looked up the wiring on this module, you need to disconnect fuse F59 in the Battery Jubnction Box (engine compartment), fuses F14 and F17 in the Smart Junction Box (near drivers floor).

Thanks for all of the info. Mine is definitely binding. Last night I disconnected the motor from the lift gate and it squeaks really badly trying to operate and the motor got really hot.
