General Central Locking Problem

[Halil]

Hi guys, I have a bit of a central locking problem on my punto 60SX (central locking is standard). The other day I started to realise that the central locking doesnt always work from the drivers door (but still fine from passenger door). My guess is some kind of faulty connection. Im a bit new to this so how do i fix?
Thanks
H

Hi, as it sometimes works ok & due to the cold weather lately, before taking the door panel off try lubricating the door lock with lithium grease or an easier option is with a light oil such as 3in1 or similar don't use any of the spray types like WD40 this will ruin locks,3in1 is also available in spray form which is ok to use.
