Hi! I have a 2004 Hyundai Matrix (right hand drive) and am having problems with the central door locks. There is no key fob but the locks are opened/closed via the key in the drivers side door. The locks have a mind of their own and have been making strange noises (like they are opening and closing) even when the car is turned off. I thought I would just take out the fuse - but low and behold there was no fuse in the door lock slot. This occurrance has gotten so bad that it is continusly draining my battery and has forced me to disconnet the batter at night to ensure that I will be able to start the car in the morning. I am not the original owner of the car! One day the hatch was making really loud noises and I managed to take the cover off and unhook the realy. But the noise is continuing and seems to mainly be coming from the drivers side door! Any help or suggestions would be greatly appreciated. I am living in Barbados, WI, so as you can imagine parts here are really expensive. I really don't care to fix if too expensive but if there is something simple to do to stop the noise that would be great. Thanks!!!!!

hi there,
Seems to be a faulty master door lock actuator or relay.
Might be an idea to check out the relays first then get a second hand master actuator.
As regards the fuse for the central locking, this along with the door lock relays are in the fuse box inside the car.
There is a 15A fuse marked D/Lock and there are two relays marked door lock and door unlock.

Hope this helps.

hello everyone, I know this an old post, but Im currently having exactly the same problem.

Im taking the car to the garage next Tuesday but they have warned me they will charge by the hour to investigate the fault, it will save me a fortune if anyone can confirm exactly what this fault is.

Thank you in advance.
