Power Liftgate System Description
Liftgate Module
The liftgate module controls the liftgate motor, liftgate clutch, and liftgate latch based on various inputs. The liftgate module also performs diagnostics on these inputs and outputs and will disable liftgate functionality and set DTCs should a fault be detected. The liftgate module is secured to the motor assembly at the left rear of the vehicle. The module requires a liftgate position learn procedure be performed when replacing. This allows the module to learn the full open and full closed positions of the liftgate.

This is not a job for a diy'er or vehicle owner .

That's why you should take it to a qualified repair shop. Before replacing part's a factory or professional type scanner should be hooked up to see if the control module will communicate an to see if DTC'S - diagnostic trouble code's are stored , before checking power an grounds . How did you test power an ground's ? voltmeter - ohmmeter ? Should do loaded circuit voltage test . using a headlamp or something that pull's at leat 4 amp's .

If it locks when using the manual switch inside the car, the problem is probably your remote. If not, your lock solenoid in the lift gate may need to be replaced.

Open the liftgate. Remove the liftgate applique. Refer to Liftgate Applique Replacement in Body Rear End. Remove the back up lamp socket (1) from the liftgate applique by turning the socket (1) counterclockwise. Remove the back up lamp bulb from the socket.

An electronic control module controls it .
The liftgate module (LGM) controls operation of the liftgate latch motor and the liftgate actuator assembly. Do you have a Liftgate Ajar Indicator ON ? Or a message in the message center driver information center (DIC) illuminates the LIFT GATE AJAR indicator ? The liftgate control module could have a DTC - diagnostic trouble code in memory !

When open, the liftgate can be closed by either a keyless entry transmitter or the liftgate close switch. When a GMLAN serial data message or switch input is seen, the liftgate module begins the close sequence. The liftgate motor is reversed, lowering the liftgate until it latches into the liftgate latch. Once latched, the latch will cinch the liftgate to a fully closed position.
Power liftgate function will only be allowed if certain operating criteria are met. Any of the following may cause the power liftgate not to function:
?€¢ Vehicle is not in park. ?€¢ Engine cranking is present. ?€¢ Temperature limits have been exceeded. ?€¢ Liftgate motor overcurrent is detected. ?€¢ Excessive hall effect counts are seen. ?€¢ System voltage is out of range. ?€¢ A DTC is set that disables power liftgate functionality. The liftgate also receives inputs from 2 object detection sensors. If either of these sensors indicate an object is in the path of the liftgate, liftgate functions will be suspended until the object is removed.

In the lift gate inside trim panel you will see a plastic cap plug at the door latch area. Remove the plug to gain access to the latch.
Good luck.

The liftgate consists of the following components:
