Rear Silverado Door won't lock or unlock

[Thorper2128]

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!!

If its not a faulty lock then I would check the install. Manually it should lock no matter what.

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..

Is this an OEM part or a Vato Zone part?

The replacement is from O'Riellys

Go OEM and watch your problem disappear for 100k miles or so. The knock offs are crap.

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.
