Hatch or liftgate ?
Liftgate Release
The liftgate release switch operates the liftgate latch electronically. When the switch is pressed, the SJB processes the input and releases the liftgate latch.
The doors must be unlocked electronically in order for the SJB to release the liftgate latch. When this condition is met and the SJB receives the input from the liftgate release switch, the SJB provides power to the latch release motor.

SJB - smart junction box , fords BCM - body control module .

Rear Liftgate Release
The liftgate can be released by operating the liftgate release switch. The gear selector may be in any position, but the doors must be unlocked and the vehicle must be stationary for the liftgate to release.
Pressing the liftgate release switch closes a contact providing a ground for the liftgate release switch signal circuit. The body control module (BCM) will detect the voltage drop and command a ground to be supplied to the liftgate release relay control circuit thus energizing the L/GATE RELSE relay which provides voltage to the liftgate latch. When the doors are locked, the BCM will disable the liftgate release system by ignoring the liftgate release switch input command and not providing a ground for the L/GATE RELSE relay.

Fuse # 10 - 20 amp supply's B+ voltage to the L/GATE RELSE relay located in the under hood fuse/relay box.
The BCM controls this relay from input from lift gate release switch.

Check your owners manual. There may be an emergency release procedure for the liftgate?

Likely a bad lock actuator in the lift gate.

If you look carefully you will find a manual release for it in the back. (You will have to crawl back there.)

First of you need to take the panel of the rear door from the inside then you can just grab the rod and pop it open. With the door panel off it is an easy thing to replace the handle just a couple screws are bolts to take lose .Also make sure you put the rods back just like you take them off may I suggest taking a picture if you can of the latch inside the door. Good luck.

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.

The liftgate consists of the following components:

• liftgate door lock actuator
• liftgate lock cylinder (if equipped)
• liftgate window glass
• liftgate window latch/ajar switch
• liftgate window glass release handle
• liftgate latch remote control which consists of the following component:
  • liftgate release handle
• liftgate latch, which consist of the following component:
  • liftgate latch door ajar switch
