My rear passenger side door lock will not lock or unlock with the remote. It does not lock or unlock when I use the button on the drivers door either. I can only lock and unlock it manually and then it works. What could be wrong?

 

The actuator that moves the mechanism to lock and unlock. It could be bad or just came unconnected from the mechanism. Do you hear a noise from inside the rear passenger door when using the remote to lock or unlock. If you do then the plastic clip that hold the parts together broke. If you don't hear anything then the actuator is probably bad.

 

I don't hear any noise at all. How much do you think it would cost to fix the actuator?

I’m sorry you are experiencing this issue with your vehicle. “oldchevy” is correct, it may be a actuator issue.

I recommend having the vehicle inspected to be certain, as prices may vary based on the cause of the problem.

Please keep us posted. If you have additional questions, please feel free to contact me.

it cost 1,300 for all 4 lock to be replaced.
we will just leave it unlocked and hope it is not going to be stolen

 

What !, If the door can be manually locked, why not just leave it locked until you need access, then reach back and unlock it.
(didn't you read Chubba's original post ?)

It appears to be an Actuator problem, not a Latch problem anyway.
In this case, the word "Lock", describes an activity, not a part.

 

Why not just replace the offending actuator? It is true that door lock actuators do tend to fail all around the same time. But, it is not always true and there is no labor savings for doing them all at once. It is four seperate repair actions. In my shop I would have recommended all four. But, just the offender is still a viable repair.

Rockauto has the actuator for $119.79. If you can remove the door panel, you can do the repair yourself and save.

 

Actuator prices may vary from store to store. You have to keep in mind quality.

 

it looks like as if sensors are not working properly here, better to check it up and replace if a need arouse with it
