Avensis Central Locking Problems

[peter23]

Another Central Locking query.. W reg Avensis 1.8 GS H/B. The key will unlock ALL doors manually and remotely. The key will NOT lock remoptely and only locks the drivers door manually. There is no solenoid 'click' on remote or manual lock. Can only lock all doors by the rocker switch on drivers door armrest. (This switch works both Lock & Unlock).

The lock line from the Integration Relay unit is at 0.4 volt instead of 12v but does go to ground (0v) when key is pressed or turned to lock position.

Is there any help for me with this ongoing problem, please???

***During an industrious lunchtime, I have further traced the problem to the 'lock switch' in the door locking mechanism! In trying to remove locking mech from door, 'wiggled' at the wires and (I don't believe it..) the mech sprang into life and is now working away like a good 'un. Both key and remote are opening and closing normally.

Thanks anyway, to anybody who, having read my plight earlier was considering a solution(?!)***
