NA central locking - passenger door not locking/unlocking

  1. My model of MX-5 is: 1991 NA Limited Edition
  2. I’m based near: Glasgow
  3. I’m looking for technical help or recommendations on: Central locking is only working on the driver door.

The central locking is only operating on the driver door. Manual key lock is still working on the passenger side. I’m assuming that it is something to do with the electrics but throwing it out there to see if anyone else has encountered this issue and can offer some advice.



Central (I assume you mean remote) locking was alway retro fit on the NA, no electrics in the door locks from the factory. It’s usually operated by generic door lock actuators, bent rods, u clamps and strips of metal to mount stuff. Most common failure is a seized actuator, get the door trim off and have a check, it’s unlikely to be a co,pled set up.

Thanks very much for the advice. I’ll get it stripped out and have a good look as you suggest. Thanks again, Sean
