Mazda central locking problem - JohnnyBoy
Central locking has just failed on the passenger door of my 1998 323F; the key used to unlock all four doors from either the passenger or driver door, but as of yesterday turning the key in the passenger door only unlocks that door.
Is this an easy one to fix? The car is still under warranty, but the dealer is 70 miles away so if it was fixable at home I'd rather do it myself.

Any help would be most appreciated.

If you feel confident take the door trim off and look for loose or broken wires to the lock switch. It could also, of course, be a faulty door switch or a broken wire where the cables go from the car body to the door near the hinge.
Probably best fixed by the garage as they could say that your 'fiddling' has invalidated the warranty.

Bertj,
Now that you mention it, the rubber boot that covers the wires from the body to the door was off at the body end. Could be that a wire has been nipped because of this.
