Fiat Punto Central Locking

[m@d h@tter]

Hi everyone. My wifes 2002 Fiat Punto central locking has developed a mind of its own in as much as when you lock the car door (either side) it locks and then unlocks itself with the interior door buttons jumping up. All four doors are closed properly but it still happens. I've had to resort to taking out the fuse that controls the central locking for the time being.

Appreciate any help.

Try removing the driver's door latch, finding the microswitch and either drying out the water in it .. or replacing it (Check it first)
That is probably the reason. Check the passenger side after that if unchanged.
Another thing worth checking is the cable bundle where they pass through the A Pillar. Some cars have a connector block .. don't know about Puntos!

Hi my son had this problem with his car yesterday. His is a Peugeot and it was because someone had put the button down when they got out and everytime he went to lock the other doors they would lock then open again. We went around the car and noticed one of the buttons was down when the others were up. Worth a look before you go to start taking it to bits.

Albags - Now you mention it, there was a problem a short while ago with rainwater finding its way into the drivers footwell which I traced to a rubber seal which had perished, situated at the base of the A pillar. For the water to get to the footwell it would have run down the inside of the door jam at the point where the cable bundle runs into the drivers door. I've replaced the perished seal and the footwell is now bone dry, but there could be moisture inside the cable connector - I'll check that out, thanks.

Theshedman - I've looked into your possibility but it's not that I'm afraid (start with the simple solution first). Also just to mention, the fuel cap and boot are not controlled by the central locking, so I can rule those out as well. Thanks anyhow.

BOl10X - I'll consider your idea when checking out what Albags suggested. I've a feeling now the problem lies in the area where the cable bundle goes into the door through a flexible connector. Thanks.
