LS430 Door Lock Issue

[sidmon]

Got a facelift LS430 with a door lock issue. Passenger front door doesn't lock on the first lock press and only locks once you press the lock again for double locking. I've changed the door lock actuator motor as it's the most common of issues but this has made no difference.

Anyone got any clues? I'm a bit baffled, it's got keyless entry (not that it's ever used) but can't see why this would affect anything. Thanks in advance.

It seems that a multitude of electrical issues on the LS430 are solved by disconnecting the Battery for 20 mins or so, if you didn't do it after fitting the actuator motor it may be worth a try.

Sadly already done to no avail 😢

Ah well, worth a mention. Hopefully someone else will be able to impart their wisdom.

I have the same issue with my rear-left door. I have a replacement (used) mechanism but have yet to fit it.
I have just gotten used to always double-locking the car.

I've given up trying to work out what's up so have bought a replacement actuator also!
