99 1.6 Central locking issue - 1999focus
Hi,

I have a 1999 Ford Focus with a central locking problem.

If I press the "lock" button on the key fob - all doors will attempt to lock, but then ping open again (lock and then unlock). And if I press the unlock button on the key fob, only the driver's door unlocks opens.

If I try locking the car from the driver's door lock, the same happens (all try to lock, but then immediately unlock again).

If I lock the car from the passenger door, all locks execute fine - and likewise if I unlock from the passenger door, all doors unlock fine.

If I unlock the car from the driver's door, only the driver's door opens - no others.

Sounds strange, eh?

Any ideas? I'm not *that* bothered, as it's a 10 year old car I'm learning in, so central locking isn't really important for learning to drive... but it's a niggle that if it can be easily or cheaply fixed, I'd like to resolve.

Thanks in advance.

On mine, when ever the doors are locked and there is 1 door open the locks wil ammediately unlock again. On my orevious car (escort) if one of the locks got stuck upon opening them then they would all amediately lock again. You seem to have both simptoms on different doors which is odd.

The system detects when a door is open using a sensor (push button behind a rubber gaiter) which is situated by the latch around 12-14" abve the sill at the rear of the door frame. Have a look and see if one is seized and check the connections behind them. Bit of WD40 maybe.

On the focus you can disconnect each door electrics individually, if you open door you will see large trunking from door pillar to door, undo one at a time while checking locking system if system works when say passenger door is undone suspect that is the door at fault. If the system stops working suspect fuse which is located behind main fuse box, you have to remove the whole fusebox to get at it, fuse is on the back on its own
