You have to crawl in the back remove the panels and find the actuator(s), when you find them check for any linkages the may have fallen off. Gm uses little clips that get brittle and break. if it is a clip reinstall rod with a new clip or reinstal rod and secure with mechanics wire.
If the actuator is broken you can hook up a volt meter to the pin outs and test for power by hitting the door lock unlock button. If there's power then chamces are that the actuator is faulty. if theres no power check ground connections fuses relays and re test. good luck

Check the unlock mechanism for the hatch. These are controlled by an electrical motor pulling a cable. If the cable came loose you might or might not hear the click click that it makes. I would also check the fuses and relays related to the system. Usually if you can get the interior panel off all the innards are exposed. I would suggest pulling that panel off, then triggering the keyless remote and see if anything moves, that might pinpoint where it has gone bad.

The left actuator arm on your electric hatch has come off.If you go into the rear of the van through the passenger area you can remove the panel around the rear window.Its a bit of a bugger but you can get in there.I know i've done it!

My wife's 2003 Yukon wouldn't lock the rear doors or hatch, but it would unlock. My problem was the lock relay was bad. There are two relays, one for lock and one for unlock. They are located in the fuse panel on the left side of the console. Open the drivers door and you will see a cover that pops off. Behind this are several fuses and relays. Consult your manual to see which is the lock and unlock relays. They are side by side on a 2003. They pull straight out. I replaced both and they were around $10 apiece at any auto store.

The lock is stuck in the "locked" position.
When you close the hatch, it is jamming the latch hook into the wrong area.
Manually open the hatch. Unlock the hatch (even tho the hatch is already open). there are two bolts holding the metal "loop", the loop has moved. Adjust the metal loop and close the hatch / lock it, etc.
