2003 suburban - rear doors and tailgate wont lock

[samuel733]

I have a 2003 Suburban. The rear doors and tailgate wont lock with keyless entry or lock switch inside. Also doesn't lock when I put into drive. I have to manually lock it , but unlocks with no problems. Front doors lock and unlock just fine. Anyone else have or had the same problem. If so, was it resolved and was it expensive. Any help or info you can give would be greatly appreciated.

sounds like the actuator is bad. I have a question for you. when you push the hatch button on dash does rear hatch pop open or does some one have to be there as you push button to open it. not all the wa just to stay open so you can walk back and lift it.
