Re: Driver Rear Door will not unlock
Sounds like an activation rod has come loose or is broken. This is located inside the door itself and it is usually threaded into your know and goes down to the latch where it is attached with a clip. This can be a real job considering that the inside door panel must be removed.

Sounds like the lock mechanism is stuck on the locked position. Since you didn't specify make and model this is a best guess. Make sure the lock is in the unlock position and try manipulating the rod connected to the outside handle (since child lock is on the inside handle won't work)
could be a wiring short, but if you hear the lock motor moving i believe the lock actuator has broken free. the rivets break free at times and i've used screws and washers the reattach the actuator in place without having to pull apart the door. try to see if you hear 1 doorlock at a time. if when you press the button, the motor sounds and theres movement thats your problem. if you press and theres no motor then you either have no power to the motor or its bad. current tester to the switch will tell you either way.
Put your ear close to the door and activate the lock/unlock. If you hear click click there is a loose/disconected lever which is moving without activating the lock. If you hear nothing something is stuck or dead. Open door panel and clean system then check again. Might need replacing the unit in the door.
I HAVE A Volvo v70 2005 Everything is dead on the passenger door. no centre lock or window actuvation. The bad part I cannot open the door ( I think when there is no electric to the door the ded bolt keeps the door locked. How to get the door open so I can take the trim panel off to see why there a problem
go inside, lift on handle, then beat the **** out of the door pounding it like your trapped in it trying to get out. latch mechanism is probably corroded and froze shut. once open, spray with wd40 and work the lever a lot. then get door panel off to see if handle is broken inside
With the window down, reach inside and find a place to the rear on the door that you can lift from. Then try lifting while you pull on the handle. I have seen the door hinge bushings get bad and let door sag, and then the latch won't release from the striker.
Its the only thing I can think of as being the problem if everything is moving inside the door as it should. If you do get it open you can check the bushings by having the door almost to the closed position and lift up on it if they are bad you will feel the play in the bushings. If this is the problem you can replace just the bushings and not the whole hinge. Thats when you are probably going to have to talk to a body shop.
purchase a paint roller tool where the roller part is only about 4" or so long. tear off the soft roller. bend the bar another 45 degrees so the angle from the handle to the part that had the roller on it is about 135 degrees. make sure all 4 doors are unlocked. get on your knees and look on the right side of the handle where it goes into the door. you will see where you will insert the paint roller. now stand up. facing the door hold the paint rollerhandle in your right hand so it is sticking straight out from the door horizontally . insert the business end into that hole vertically. you will then feel for the "pad" which you are going to depress inside the door. when you feel it, turn the handle you are holding to the right slightly because you are now gong to push on that pad towards the front of the car. in order to do that, you need more clearance and that is why you are moving the handle. use your left hand to stablize your tool at the bend. at the same time put some of your weight on the door as if you were pushing it closed. you will hear it unlatch. lift the door as if the door handle worked. voila. the door is open.
