I am having issues with the central locking on my 6N2, it either goes completely haywire or nothing happens at all.

Here are the symptoms......

Drivers door - Nothing happens when I try to lock/unlock the car from here. The lock operates like a non-central locking car, so I can at least lock this door from the outside.

Passengers Door - When I lock it from here it causes the windows to wind fully down, but doesn't operate the lock manually....to me this doesn't seem right?

Internal switch - Works perfectly, all locks open and close as they should. Pump can be heard operating in the boot, it doesn't sound labored and is only on briefly (enough time to lock the locks)

I have checked all the connectors (in the locks and pump) the are seated properly....everything is fine as far as I can tell, without doing a continuity check on the all wires involved.

Also having a problem when operating the passengers windows from the drivers buttons, it goes down but doesn't come back up. I have tested this with another fully tested/working switch and I get the same effect. I know the central locking and windows are interconnected, so this could all be related.

And the new battery has gone flat after a week of not using the car....could be related?

Anybody got any ideas or had this problem before (and solved it)?

If it wasn't for the fact that the petrol cap is on the same circuit I wouldn't actually be bothered and either live with it or buy a remote kit. I am going to go fetch a new battery now, while the other one recharges, and take the doors apart again so I can remove the lock mechanisms!

Problem Solved!

New battery and a good clean up of the door locks so that they centralize properly when you let go of the key seems to have done the trick.

Inside the lock mechanism is a little twin lobe 'cam' that operates 2 micro switches, open and close, and the grubby locks clearly weren't returning back to the neutral position or were out of position. Which explains the driver side doing nothing and the passenger side opening the window. I guess this could have been causing something to stay powered up, hence the dead battery.

Still got the problem with the passenger window operation from the drivers controls though.

I have come across these when the windows go down on their own for no obvious reason.

If this happens and you hold the key in the door lock, keeping it in the 'lock' position for a few seconds, the windows will go up, after that, they generally work normally (at least 'till next time )

The auto up & down function for both external locks now works flawlessly, it just appears the locks were sticking and activating the switches.

I'm having all of them problems . But now the passenger lock has stop working all together . And I'm trapped out my car any help would be nice thanks

Well I am still having an issue with the passenger electric window operation with the drivers switch...but I just haven't gotten round to test the wires, although I have checked the wiring at the door hinges and there are no obvious breaks.

As for the locks, my issue appeared to be the lock mechanism being dirty and full of crud, the locks are spring loaded so that they return back to the 'neutral' position after the key has been turned. Mine was staying in the open or close position, after a strip down ,clean and light oiling the mechanism now runs as smooth as the day it was made.

And everything works fine now.....not sure how much more help I can be. Like normal I just ripped the car apart, played with it until it did what I was expecting and now it works fine. I really should take more pictures, especially if it's a common problem like this!

Try giving the locks a good spray with WD40 and work the key in the lock, I then used silicon spray to lubricate the parts.
