Hi ive just bought a mk4 fiesta and have a strange locking problem. The central locking worked but didnt include the front passenger door at all, I took off the door card and the previous owner had disconnected a cable that clips into the door lock.

I re-attached the cable which caused a different problem which is...

When I now try and lock the car (via drivers door, as previously) the central locking makes its whirring sound a couple of times then gives up, no doors locked! Upon closer inspection it doesnt seem to make a noise in the passenger door, HOWEVER if i try and lock the door via the latch inside (again, passenger door), it will make a whirring sound before pushing the door handle back out of the locked position.

Logic would suggest a faulty passenger door lock or something, however being new to fords I shall leave my logic well alone!

Sounds like these symptoms may help somebody in the know to a conclusion. Any help is very much appreciated!

 

If the system is factory fitted and the wiring original (not a DIY job) then yes, it is likely that the white plastic locking mechanism is faulty.


These are cheap and easy enough to replace. Just bear in mind when you do look for a replacement that there are two variants:4 pin and a 6 pin.

The extra pins are for deadlocking, so if you don't have deadlocking then it’s the 4 pin you’re after.

Regards, Phil.
