problem details
same crap obviously a defect. back locks wont lock when pressing all locks down. sometimes works 90% of the time crawling across to manually unlock. or going back opening and manually locking doors. major inconvience consider amount of money spent on this vehicle and amount of similar incidents on here.

The power lift gate actuator stopped working. tried and after market replacement which worked for approx. 2 weeks. Ordered another from another company and it work in reverse, it would lock when you hit the unlock and unlock when you locked the vehicle. That one also only lasted approx 1 week. To buy one from the dealer is approx $450.00. I have found that this is an on going problem with many complaints so I do not know why there hasn't been any type of recall on this

Actuators failed
Back passenger door lock failed. Not repaired due to cost.
I had the same problem as another visitor. When trying to open the hatch via the button on the handle (liftgate) the liftgate would sound like it was closing. If you quickly pulled you could manually open the liftgate. all other buttons did nothing (related to Liftgate). The solution I found to fix it was 1. Close everything and open the hood. 2. Detach the negative cable from the battery for at least a minute 3. Attach the negative battery cable 4. Unlock the truck and turn the key to acc (dont start it). You should hear the sound of doors clicking like they are unlocking 5. Liftgate should now work Optionally, remove the Fuse (44 i think, check the fuse guide for power lift gate) and then try and open, then plug fuse back in. I did this before turning the key so perhaps it was just the battery detaching that reset everything. I was pretty darn happy i didnt have to buy a new liftgate motor.
1997 C2500 LT 7.4L 4x4 85,000 actual miles The door locks will not actuate using the lock/unlock button on the driver side armrest, whether key on or off. All door actuators work automatically after the truck is started and put in gear, and unlocking when the truck is shut off. Chevy dealer was changing oil/tune it up when it occurred and after having it in their shop for 5 days - could not find the problem.
Rear passenger door actuator does not work
bad actuator rear door
Rear hatch jams up and won't open.
Chevy dealer wants $130 to even look at the problem which they believe is the actuator in each door
The rear passenger door, the driver side door, and the barn doors In the back will not lock or unlock because the actuators have failed. They give a little nudge when you push the button, but nothing happens.

The rear doors on the Suburban 1500 may or may not unlock with the auto lock mechanism either on the front doors or through the programed unlocking when engine is stopped. This issue is sporadic and the doors may or may not unlock after multiple attempts using the unlock button on the front doors.
