Morning all and a happy new year.

A new minor issue with my focus is that the drivers door does not lock/unlock when I press the button on the remote fob, All the other doors operate via this method and the indicators flash for the deadlock etc. The drivers door locks/unlocks fine if I use the key in the door and this method also operates the central locking (All doors) without any problem. Is it a case of the drivers door mechanism running on a seperate fuse that may have blown?

I've seen a few central locking issues but nothing like this on here, Can anyone help?

The driver's side lock motor does not have a separate fuse. It could be a broken wire in the loom where it passes through into the door - this one gets the most flexing of any on the car - or a faulty lock motor.

The drivers door solenoid operates the other doors, so I would be looking at that first. It might just need some wd40 sprayed on it.

I have this problem too .

I don't fix it , because i have to change all lock door system and it very expensive.

I lock the car with key always .

Some people try to use wb40 for lubrification the system .

Not strictly correct. It's the microswitch in the lock that triggers the other locks and the OP states that they work if he locks the door with the key so that must be ok. I therefore stick to the idea that it's a dodgy solenoid or a break in the wiring to it.

Looking around the internet this solenoid seems to get mentioned a fair bit. Question is, What the hell is a solenoid? And where am I likely to find it? Im guessing this is going to involve me removing the drivers door card (cant wait for that). I've nipped out and saturated the lock mechanism, keyhole, and gaps around the handle with WD40 just in case something might have seized up due to the recent minus temperatures.

[mjt]

The solenoid is the linear motor that pushes and pulls the locking mechanism. It's part and parcel of the door latch and, yes, you'll have to take off the door card to get to it.

Because all the locks work together there's no reason why the driver's lock would be more likely to have problems than any of the others. Of course it's possible that water can enter the via the keyhole and freeze inside the mechanism but since you said that the lock worked ok with the key that doesn't seem to be the cause.

Hi Cress

have a look at diagrams attached it would seem that the locking is controled by central
unit A11 and not drivers door.
i would start by chgecking for damaged wire as suggested by MJT.

Thanks for the advice guys.

After letting the WD40 do its stuff and, as a last resort, giving the door panel a right good whack it seems to be working fine. Will keep hold of the links and stuff above incase it re-occurs.

Thanks again.
