I'm about to buy a Peugeot 306, 1993 vintage.
It has an intermittant locking problem, as in sometimes you lock the doors via the drivers door, and the locks unlock themselves straightaway, as if a door isn't shut properly etc.
Someone else I know used to have a similar problem with the 306 he had at the time, so I presume something is worn out like maybe whatever switching is on the back of the door lock, that triggers the central locking for the rest of the car - any ideas, as this seems to be a common 306 problem.
TIA
