try to spray like WD40 to release.

The locking mechanism on the rear lift gate for the Chevy Uplander has some plastic and rubber-coated parts that can get jammed. If you can pull back the panel from the inside top near the glass, you can reach down and try to spray some silicone lubricant into the lock. This could help get those parts unstuck so they spring back when you pull on the handle latch from the outside. Once you get the rear hatch open, I recommend taking out the locking mechanism and thoroughly lubricating it. Your rear lift gate will start to release very easily from then on.

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.

This sounds like a BCM problem. This could have been affected by the radio hook up. But usually dealer hook ups are play and play after the radio is programmed to the vehicle. This is not something you should try to fix. You mess with the wrong thing and you could void your warranty and have to pay to have it fixed. I suggest you return it to the original dealer and have them repair it.

The liftgate will lock any time the vehicle is shifted out of park on vehicles equipped with an automatic transmission and at vehicle speeds exceeding 5 kph with manual transmission. This happens in conjunction with auto door locks if enabled or independently of auto door locks if the feature is disabled. This ensures that the liftgate is locked anytime the vehicle is shifted out of park or when the vehicle is in motion.
The liftgate lock relay supply and coil sides receive a constant voltage through the battery voltage supply circuit and the ECC fuse. The normally closed contact is connected to ground and the control side is connected to the body control module (BCM). A lock function will occur when a door lock switch activation, keyless entry lock transmission, auto door lock function or a liftgate lock function has been received by the BCM. The BCM will then ground the control side of the liftgate lock relay. This energizes the relay and allows voltage to be applied to the liftgate lock actuator lock control circuit. Since the other side of the liftgate lock actuator is connected to the normally closed contacts of the door unlock relay to ground, the liftgate will lock. When an unlock function occurs the BCM will ground the control side of the unlock relay and the rear doors and liftgate will unlock.
The BCM also runs diagnostics on the liftgate lock relay control circuit and will set DTC B3825 as current and also send a Class 2 message to the DIC. The DIC will display REPLACE LIFTGATE FUSE to inform the driver that a fault has been detected in the liftgate lock circuit and that the liftgate is not locked. Faults that will set the DTC and cause the DIC to display the message could be any of the following

I would put my money on the "Liftgate Unlock Relay" In I/P to the right of the steering column. Has 5 wires - pink/orange stripe, brown/white stripe are what to look for on this relay. 2 others in same area for doors.

Next it could be the liftgate lock switch in the liftate.

You should have 12 volts on the pink/yellow sripe wire at the lock switch when you press the unlock button.

please rate as fixed if this solves your probelem.
