i noticed recently that when unlocking the car from the key (central locking) that it unlocks all doors but the rear left one. i can see that the door pin only comes up about 1/3 of the way up...when i lock it, the door pin goes down as normal. same thing goes for when pressing the central locking button in the car.
i can unlock the door from the door handle inside and push the door pin to manually lock it.
any ideas on how to fix it?
Got my MOT soon. this is a fail, right?
