Rear Silverado Door won't lock or unlock

Recommended Posts

Hello all,


Been having a little issue now that I thought I had fixed but obviously not. A few weeks ago, my rear passenger door stopped wanting to lock with the key fob and using the button on the drivers door but it would still unlock with them. I could still manually lock and unlock. Did a little research and thought forsure it was the actuator. Got a new one, put it in,and worked perfect, thought my problem was solved. However, a couple days later when I went back to recheck it and was worse off now. My fob and driver door button would not unlock it, along with I was not able to manually lock or unlock it, it was like seized up and wouldnt move. Got another one through warranty and the same thing happened..so now I am kind of lost and not sure where to go with it. I put the original back in and it still wont lock, but can at least do it manually.


I have checked fuses and it is only the one rear door. Any ideas?


Thanks in advance!!

Right when I install it it works like it should. Then I don't think about it since it is a rear and then a week later I check and it's seized. I took the door panel off too to make sure it's not jamming on something and it;s not, but i can't even push the switch on the actuator up or down. Might take it in and see if they will replace the actuator under warranty again. I am just stumped on how it works for a couple days then jams up, and now when I put my original in, I would have thought it would jam that one up too but it doesnt..

Does GM or Chevy have an official part website? or any sites you recommend? I guess or any to stay away from? I just googled OEM of them and a bunch of sites come up..just want to be done with it. Or else I will just stop up at chevy tomorrow and order one.

      Hi, I have 2 questions. One, I want to do the HD Front end conversion on my 2007 NNBS Silverado1500. I know what I need, and I have decided on the 2011-2013 HD grill and bumper. I have gone on line and seen some people go with the 2007-2010 HD hood and some people go with the 2011-2013 HD hood. Would any one know the difference or if one fits better onto the 1500 truck? And does anyone know how to install the bumper? And the second question was, How can I convert the truck into full electric mode? I have manual windows and no power locks. My truck is extended cab and I would wish for the back windows to work as well. Or does anyone have a really good video on what parts I need and how to do it step by step? I am by no means a mechanic but i do work on my trucks here and there on small things. Thanks in advanced!

      I have a 2004 Chevy Silverado 1500. The door lock on the driver side rear works sometimes, the driver side works sometimes, and the passenger side front does not work. I replaced the actuator on the passenger side door and that didn't work. I've had this door fixed for this problem many times when it was under warranty from the dealer. Now today all door locks worked for a couple of times and now its back to the old problem. The door lock on the driver side rear works sometimes, the driver side works sometimes, and the passenger side front does not work. Also, the driver door and driver rear door locks sometimes when you put it in drive and then unlocks when you put it in park. This is driving me crazy. Does anyone know what is going on with this? and how to fix this?

      I hope this is the appropriate sub group, if it is not, I would appreciate an admin moving it to the right one if possible.
      I have a 2008 Tahoe with door lock issues.  All 4 doors are acting up, I know the left rear motor is out, because it will not move at all, but the other three are acting strange.
      Usually, on first try, all the doors will unlock, or lock with the remote or when put in drive or park as expected.  A little weak, but work.  But if the button (remote or door buttons) are pushed several more times,
      the locks do not lock or unlock.  They act like they want to and move a little, but do not move completely.  THe more I push the buttons, the weaker they get.  I thought the actuators or motors migght be bad, but they do move, just not enough.
      But on some occasions, usually first try when going to the vehicle, they work normal.
      Do I just change the door actuators, or is there a different problem I should be looking at?

      Thanks for any advice.

      Hey guys, 
      Hoping to get some input on this as its a little frustrating. My key fob and lock and unlock button on the drivers door do not work at all. I have an 09 Sierra, and have already replaced the lock button as that was the easiest piece to eliminate. There is power to the button, and when i push both the lock and unlock buttons i can hear clicking from the secondary fuse panel. Someone has suggested that i check out the relay,  but i am unable to locate and find said relay. All the fuses have been checked and rechecked, and are all in good shape. Dont really want to take it to a shop for this as i can likely do it myself. 
      Thanks in advance
