came across this thread im having the same problem. anyone got any solutions?

Digging this up
 

Tales from the grave :)

I thought this may be better than opening a new thread.
I have an intermittent problem with LOCKING my doors (the trunk works fine).
every once in a while (happening more often) it is not possible to lock the doors via the remote or the button on the driver / passender door.
Locking them with the key or the little handle thing works fine.

If I press the remote or the button, the lights flash (as normal) and I hear the some faint "grinding / moaning" from inside the door near the lock - and the door is still open.

If I press the remote / button and it locks the doors I hear a load and solid "chunk" as the door(s) lock.

Now the question is something else bad (like mentioned relay, fuse, ground) or do I new 4 new door lock actuators?
and if yes how to I determine if I need the ones "does not include connector for Anti-Theft system" or the ones with, without taking my doors apart?

had the chance lately to have my fingers on the relays while pushing the lock button and the doors wouldn't lock, but the relays did a strong click.

So the fuse is obviously ok, since without a fuse it wouldn't do anything.
the relay click even if the doors don't lock.
Should I next check voltage for the actuators at the relays or is there another prone part to fail.

I don't wanna take my doors apart right now.

I’ve had this problem for along time now but it never bugged me enough to try to fix it; Ill start trouble shooting soon to see if I can solve the mystery once and for all.

as the export models don't honk the horns, it can be quite a security issue if you can't lock the doors and don't recognize it.

I'll be very glad and happy if you could look into this asap

okay
