Hey all,
I have been having some issues with my rear door locks
Both doors, not the rear hatch.
I will lock or unlock the doors, but the locks in the back dont seem to work properly.
Either they will unlock, lock, or they will sorta lock/unlock (meaning that the lock moves but not enough to lock or unlock the door

Does anyone have any ideas.
Just seems weird that both the rear doors have this happen in the same way.

Any help is appreciated

 

My wife's 08 had this issue but with all four locks. They also made a noise like the gears were stripping, a sort of buzz when you hit the unlock buttons, fob or interior. One, two, or three of them would screw up at the same time and seemed worse when it was hot out. I replaced all four and had no problems with them since. They're just cheap Hecho en Mexico units and I think the motors cause the gears inside to strip.

 

I had the same problem ,changed driver and rear driver door lock actuator no change and I was about to change the liftgate actuator . I checked the fuse box by driver door and found a 20 amp fuse says LOCKS changed that and everything is good now.

 

I'm having this EXACT SAME ISSUE. Did you ever figure it out? I tried replacing the "LOCKS" fuse but it didn't make a difference.
