Question about 2005 GMC Yukon
2005 GMC YUKON REAR HATCH ACTUATOR will Buzz when locking the door. Does the actuator need to be replaced?
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.

Harris, did you find a solution to your problem? I am having the same issue on my 04 denali. Rear doors and tailgate wont lock but the unlock fine. Front door function normally? let me know.

Could be the latch mechanism for the door is sticking. You could try using some white grease on the latch and the contact where the latch hooks to. You can purchase the grease from most auto parts stores. You will not need to use alot. Just apply a small amount to the mechanisim and then work it in using the manual handle. Then open and close the door several times to feel the "action". Then apply a little more and repeat. This should loosen the latch and get it working again. Also make sure that none of the tension springs have come loose on the latch. And check the seal around the door and make sure it is not pinched and has a proper fit.
