Hi,

I just today replaced the left hand side rear central locking motor because the old unit had failed which meant I couldn't lock/unlock the door by the fob. Since I have replaced it I have noticed another issue.

My car has the double locking function and when I press lock on the fob once it locks the two front doors and the door with the new motor, however, the right hand rear door only locks if I press the fob button twice to double lock the car. Does anyone know if its supposed to be programmed like this and if it can be reprogrammed or does this mean I have two faulty motors?

Have something to contribute?

It was just the one door that wouldn't lock/unlock all the others worked fine. If you have checked fuses and wiring maybe its the module for the central locking at fault on yours?

yeah could be no1 said about that, if you lock it with the fob or key you can hear it trying to (clicking noise from all the doors) but it cant, and if you lock it from the inside it lock then unlocks straight away, ive had every door panel off at once and dissconected every motor one by one .ie unplugged drivers door motor and tryed it but still the same so plugged it back in and unplugged passenger side and tryed it but still the same so plugged it back i etc. yep tryed all the fuses.

Have you tried the test function to see if all the door switches are working properly? Sounds like the car thinks a door is open and that why it isn't locking.

here is a link to the procedure http://www.pistonhea...sp?h=0&t=595724

yeah tryed that there all fine im lost with it, iv got to disconnect the battery everynight to lock it manual, only thing i can think is the drivers door is hard to open from the outside if you pull it lightly it dont open youve got to pull it hard its like the cable has streched but there aint a cable its a rod.

Well my problem just changed now when I press the fob once it only locks the rear left hand door and none of the others. If I press it twice all the doors lock ok so I may just accept that I have to live with the issue.

As for your issue Dan do you ever get a noise whilst driving along that sounds like the locking motors are trying to lock? Mine can do that from time to time and when it does I have to manually lock the passenger front door with the key then press the central locking fob and all the doors will lock. From the amount of threads and posts on this issue I think the central locking is a common problem on the Focus.

Tried this and all doors flash when opened and shut!

yes every now and then it does this, my problem is I press the unlock button and all doors unlock except the drivers. I have to put the key in to unlock. When I try to lock with the fob you can hear all the doors except the driver try to lock the instantly unlock, then I put the key in and turn and all doors lock?

Seems peculiar...

so nothing changed? it just started swapping how it locks?

Try this...

Unplug the battery for half an hour...

Open all doors, boot and bonnet... lock the car with single click, unlock, lock with double click, unlock. After each lock, go around the doors, and watch each of the locks on the door, see if they have any movement and lock or not (i.e. do they vibrate as if they try to lock) - this confirms that the mechanism itself will be moving correctly under single and double press... This should rule out a fault with the central locking 'box'

Close one door at a time, and single lock - check its locked... then unlock, and then double lock... check its locked...

Try this repeatedly until everything is closed.

Does it behave correctly?

Nothing has changed including the way it locks, when I press he fob I can't hear any motor or vibration from the drivers door but it does lock the whole car when the key is inserted?

the door lock issue is simple its the fob hold the lock button down and then with the lock button held press the unlock button for 5 secs now all doors will unlock when the fob is pressed once unlocking door can be as simple as water in the lock remove top torque screw on side of door nearest driver spray wd40 in a down wards 45 degree angle refit the torque screw and try if its still the same give it 20 mins then try again worked on my mk1

have you checked the wires that go through the rubber grommet into the door theres a multiplug there and water can get past and cause the connectors to go all green thats worth a check otherwise it may well be a dealer job
