Drivers door wont Lock

[jamesmprint]

Hi all,

Firstly thank you to anyone who can provide any help.

So out of the blue my drivers door has stopped locking/unlocking using the key fob, all other doors and alarm work fine when the fob is used. The only way i can lock the drivers door is either with the manual key or with the door closed and manually pushing the lock down (this doesn't feel stiff or anything). The windows still go up or down when holding the fob so I can also lock by rolling windows down, pressing the lock and rolling windows back up.

If I open the drivers door after locking the alarm goes off so the car does think it is locked.

The only thing that I've noticed about the door was last week the speaker stopped working although that has since come back so not sure there is something related?

Is there a simple fix here that I should investigate/eliminate before taking it in and spending money that I dont have, Can a fuse be gone? Could there be a loose connection?

Any help is greatly appreciated.

Many Thanks
James

To what extent code readers can read door modules on such a car I do not know.

If you are handy, may be worth getting the door card off and checking the actuators to the lock.
