I need to remove the glass in the rear lift gate in order to do some rust repair. I would like to know how to do this.
Also I have to remove the rear handle and lock assembly.
Any help would be appreciated.
We ended up using a wire attached to 2 wooden handles passing through the gasket material between the glass and the metal frame and sawing the gasket. Quite a slow job but it worked. As far as the handle goes it'll probably be a case of breaking the plastic hex bolt that holds the assembly and replacing it or maybe the whole thing.

How do you know it need's a switch ?
Rear Hatch/Gate Description and Operation
The lift gate can be opened by operating the switch on the instrument panel. Battery voltage is supplied to the lift gate actuator through the body control module (BCM). The BCM will pulse the lift gate actuator when a release input is received through the key fob, or the instrument panel switch. Did you test voltages ? Check for BCM DTC'S - diagnostic trouble codes ?
The lift gate switch is an input to the body control module (BCM). The BCM supplies battery voltage to the signal circuit and when the lift gate switch is activated the signal circuit voltage goes low. The BCM controls the lift gate release actuator assembly through the LIFTGATE relay. When the lift gate switch signal is activated, the BCM enables the LIFTGATE relay by applying battery voltage to the lift gate relay circuit and the relay is energized when the BCM grounds the LIFTGATE relay control circuit. When the relay is energized battery voltage is supplied to the lift gate release actuator assembly through the lift gate release actuator control circuit.
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.

This sounds like you have a grounding problem with your hatch circuits. This type of malfunction usually occurs when two systems (the hatch lift and the Lift glass release) are supposed to be sharing the same ground, but one of the systems has a bad connector or a broken wire. It then "activates" the other system by grounding THROUGH the system that it is supposed to be sharing ground with.
What I would do in your case is to take a HARD look at the wires that are in the conduit that runs between the lift gate and the body. These wires flex every time the lift gate is opened and closed, and are prone to breakage.
The way you describe it, it sounds like the lift gate motor is losing contact at about 1/3 to 1/2 of the way up, and that is when it grabs ground through the glass release solenoid.
FIRST TURN OFF RADIO THEN DISCONNECT NEGATIVE BATTERY. MARK POSITIONS OF WIPER ARM ON THE LIFT GATE GLASS,THEN REMOVE WIPER ARM COVER AND NUT AT THE PUTSIDE OF THE LIFT GATE, THEN THE BEZEL, DONT SCRATCH PAINT ON THE LIFT GATE, REMOVE THE UPPER AND LOWER LIFTGATE INTERIOR TRIM PANELS, DISCONNECT THE ELECTRICAL CONNECTOR AT THE REAR WIPER MOTOR, THEN REMOVE THE TWO BOLTS SUPPORT WIPER MOTOR HOLD WIPER MOTOR IN PLACE WHILE REMOVING MOUNTING BOLTS THEN INSTALL NEW WIPER MOTOR THEN PUT EVERYTHING BACK VISA VERSA.

depends on what model you are asking about . some of the rear lifte gate struts are bolted on . just remove the bolts while supporting the real glass or lift gate .And some struts use a little push clip at each end of the strut . these you can use a pick or a small flat blade screw driver to pop out of place . the new struts should have them already installed on them . so they just snap back on . just remeber to support the gate while changing the struts
