A minor fault, but amazingly annoying. The driver's door lock now only unlocks and locks the driver's door. I have to use the boot or the passenger lock to use central locking, which both happily lock and unlock all doors, including the driver's!

However, I went to try to fix it this morning, unlocked the driver's door only, opened it, and about 5 secs later all the other doors unlocked too! Worked fine for 5 mins, lots of goes, then when I triggered the alarm it went back to looking after its own door only.

When you turn the key in the drivers door, the other lock plungers move slightly (barely perceptible), but they seem to be trying to go the opposite way, almost like the driver's lock is out of sync.

The alarm (piranha) has never worked with the central locking, although I know it should - I'm sure it's linked to the problem. Reading some old posts, I imagine that the alarm is linked to the famous 'blue' wire the comes from the driver's door to work the central locking. Maybe the problem is where the alarm joins the original loom?

Any help gratefully received! Anyone else managed to get their driver's door out of sync with everything else, and more importantly fixed it?

Cheers

Haig
