SOURCE: My 2006 Yukon tailgate will
I have the same problem. This is a faulty actuator switch according to GMC which controls the tailgate and the hatch window. My 2006 has 90,000 miles on it (I purchased new). Warranty is not an option and cost is estimated @ $600.00 in Arizona. As far as I am concerned, it is safety related issue and should be a recall since there isn't a mechanical way to open the tailgate or window as an escape route in the event of failure.

Check battery voltage. if above 13.7 volts move to rear lock actuator and measure battery voltage at actuator if above 13.6
replace actuator if below specs. check grounds and alternator out put as follows, alternator output 13.7 to 14.25 volts. key off battery volts should be 12.90 + - 3/10 of a volt and about the same voltage at the actuator. let me know. kindest regards Bill

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.

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.
