Back passenger door will not actuate
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.
Rear door will not unlock.
electric door lock on the passenger side just stopped working
Door locks slow and wont lock
doors power locks wont work....doors open just with a key
Actuators failed
rear hatch door doesn't lock..all other drivers side and passenger doors DO lock
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
Front door locks stopped working locking passenger door shut and driver stuck unlocked. Replaced driver door lock actuator for a test. It worked but now a month later stopped abruptly. And there is no reason for it. Door panel removed revealed all components in correct position. Why is it failing again? any help would be greatly appreciated thanks, james
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.
Back passenger door lock failed. Not repaired due to cost.
Rear passenger door actuator does not work
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.
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
Rear barn door lock will only unlock when the key is turned 90 degrees to the "unlock" position. And this is because the push button to actually open the door won't "connect" to the interior door parts to unlock it. Now, after all this time, the button and the spring popped out in my hand and now I need to replace the entire lock, I think. Any suggestions on how difficult or easy this might be?
Back doors wont lock or unlock. They do move a little but not enough.
3 of our 4 doors will no longer stay shut within a week of each other. All electronics must be replaced. $$$
