Rear door lock won't pop up in 2008 Buick Lucerne

SOURCE: rear door lock will not lock or unlock

sounds like that rear door lock will also not unlock with the switch either, correct ? It might lock , but not unlock. Door lock actuator needs to be replaced.

SOURCE: cannot locate the battery under the hood

The battery in my 2007 Lucerne is under the rear seat. Just pull up hard on the fornt of the rear seat bottom.

first purchase the door handle assembly then remove the door panel. make sure the window is up and reach in and disconnect the rods making a note of which one goes to which one. unbolt the door handle and remove. the new door handle may come with a new rubber seal for it. position over new handle and reinstall. make sure to search the door panel for hidden screws holding it on before you pop the clips.. hope this helps

Hi Dear Lov, Remove the plugs from the arm rest and behind them there will be deep seated screws. Push in a long screw driver and remove them. Next lift the window control buttons and when removed from the housings disconnect the electrics. (Keep the switches handy) next take a flat blade tool and starting at the bottom of the door, insert the blade between the panel and the door and gently pull the blade towards you. When the studs pop move to the next until all are released. Lift the panel off and then refit the switch to the cables. Reach inside the door and feel for the operating rods which extend from the handle to the latch mechanism. at each end you will feel plastic clips which will rotate away from the rods when pushed in the same plain. These clips beak easily so be careful. It is worth getting a mirror and flash light and studying them before trying to release them. Check both sides as the mechanism may be different at each end. Once disconnected you will notice two hole opposite the exterior door handle, through which a socket spanner fitted to an extension will fit. Remove the nuts and then remove the handle from the outside. When fitting everything back together make sure the rods are correctly fitted. You may find you need to lift or lower the window, or maybe remove it completely to do the job. Regards John

My friend just had this problem and he reached in and pulled the inside door handle back as far as it would go, and then let it go, allowing it to 'snap' back. For some reason this fixed it. We have no idea why. By doing this on one door, both rear door locks freed up and the rear locks are now working. Before, both rear locks were stuck and you could not open the doors from the inside nor the outside. Not sure why it works, but maybe it will work for you!
