Central Locking Goes Open/close/open/close (And Repeat)

[Richard2005 2]

Guys,

Central locking has been having a hissy fit of late (as per the title). Is this the c/l controller on the way out? If so, does anyone know if they're still available?

 

The battery has been flat a couple of times as a result of the open/close. Grrr.

Maybe one of the central locking motors is on its way out , more likely to be water in the control module up in the roof console . The aerial mount could be letting water leak onto the electrics .

I have a similar but intermittent issue with my 405, I haven't fixed it yet so not much help I'm afraid.

 

Mine does the same as yours, locks and unlocks several times but:

(A) it only does it when unlocking, never when locking.

( it only seems to do it in winter, it hasn't yet started to do it this year so it might be affected by the cold.

© when it is doing the unlock-lock-unlock-lock cycle, if I pull up hard on the passenger (interior) door lock pin then it stops pissing around and stays unlocked until I press the key fob again.

Thanks for the replies all. I'm away this weekend, but will look at the roof when I can.

 

Also, I think this does happen following rain so rings true.

 

Thanks again

It does that when it thinks that a door is open, give all the locks a good dose of wd40 or similar, preferable from inside the door.

Have had this happen when a battery is on its way out and losing charge, most noticeable when the nights start getting colder.
