I know there has been much on here about this topic but here goes anyway. I understand that there are 3 microswitches in the driver's door latch. One of them switches the earth/ground for the rest of the door latches, so if it plays up the other locks lock/unlock randomly as mine have begun to do, but the driver's door remains unlocked (whilst the car is being driven). I've looked at a Youtube video which shows the black plastic piece in the door latch moving across the microswitch with the red/black connections, depressing the pip. I understand that this is when the driver's door is locked and that it interrupts the earth connection, thus de-energising the other lock motors. It isn't what I expected and I may have misunderstood the narration. What I want to know is how I can temporarily control the other locks with a manual switch until I am ready to remove the door latch and sort it properly. Is the problem with that switch due to the pip wearing a groove in the plastic so that the pip is not depressed properly and the earth is intermittently connected, because that would suggest that the pip is depressed when the driver's door is unlocked, which is not what the chap on the video seemed to say? Are the necessary components to effect a permanent repair available? Presumably the black wire on the back of the double microswitch is a common earth for the blue wire (door ajar) and the red wire (C/L), is it? In which case if I disconnect the red wire and provide a temporary 'permanent' on/off switch to the black wire, I can control the locking of the other doors with that switch? I know there is a fellow who can supply reconditioned latches, but I'm looking for a temporary remedy now and my own repair to the latch/switch later. Thanks..
