Rear Door Stopped Locking

[Ginettamad]

My rear door has stopped locking with the central locking. I've checked the wires into the door and none have broken. When I operate the locking I do here a slight whirr from the door but the handle does not move in. It manually locks ok thankfully.

Any obvious idea's?

Sounds like the lock motor to me - possible its stripped a part internally hence it moves but nothing happening. You should be able to find a replacement unit and just swap it over, you will need to remove the outer handle first. If you get a replacement unit then before stripping it out completely if you operate the catch with a screwdriver to latch it and then connect it to the cables for your existing lock you should be able to see if it operates how you expect it to, proving if that is the faulty bit.

 

Broken wires would normally result in no noise from the lock area.

 

The locks are handed (you need one from the same door as the one you have the fault with on the same side of the car)
