Central locking not locking all locks from drivers door, will unlock, but not lock. working fine on passenger door with key, locks all. switch to activate central locking on drivers door unlocks but doesnt lock.

It's only an educated guess. If all other locks switches are working it' either the switch panel itself or an electrical short. Switches are popular, get it checked first

you can remove the central locking fuse , this will stop the lock/unlock constantly , the problem is usually with the drivers door lock mechanism , that is perhaps why you cant lock/unlock with the key, lock from inside vehicle and get out passenger side, that lock should work with the key until you get the lock changed on drivers door

Check for a bad switch in the door.
Water leaking from the rag top-door seal joint often drains into the switch, causing a short or bad contact eventually.

If the key turns in the lock, but does nothing, then the linkage has become disconnected or broken. The key is mechanical to the lock and the lock has a electrical switch to operate the central locking unit. Could be a simple broken clip from the lock barrel. Hope this helps

Method 1: Press lock or unlock button 4 times in succession. Method 2: Switch ignition ON and OFF. Within 10 seconds press lock and unlock button in succession.
This is the only manual reset
If this does not work go to your local auto electrician
The probable fault could be central locking activator passenger door

turn key twice when opening, ie turn right. once drivers door will unlock, turn twice passengers doors will unlock, and locking is turn anti clock wise once will lock all doors, turn twice will set door dead locks.dead locks will stop openand lock internal button working and handle from opening door. the same actions can be applied to the remote one press drivers door, two press passenger doors, press and hold unlock button for 5 seconds and rear window will open.

Unlock vehicle. Enter vehicle. Close driver's door. Switch ignition ON and OFF. Remove ignition key. Press and hold unlock button. Press lock button briefly 3 times within 10 seconds keeping unlock button depressed. Release unlock button. Some models: LED flashes slowly for 10 seconds. Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously.

My friend had this problem. The automatic locks armature sticks sometimes replace them. Two check for a short in the door wiring.

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.

If all the doors do not lock or unlock when using the passenger side switch, then the switch itself is probably bad.   If the passenger side switch locks or unlocks all the other doors except for its own, then the power lock solenoid inside the door is bad or jammed.  If it is jammed, try locking and unlocking the door manually while activating the switch to work its way free.
