Not sure Why????

[Tan81]

Just wondering if anyone would know why my VT would be locking and unlocking without me doing it. It happens when I'm driving along and also when i'm not. Any ideas???

Could be a problem with wiring, or (not sure if this is as possible) but could be getting signals from a radio station or something like that, that your car locking reacts to...

But I would suggest checking the central locking wires as well as the pumps...I know in some cars if the pump doesn't go out all the way it will come back in (ie. if it doesn't unlock properly it will lock again)

I'd go straight to the Body Control Module. Could be on the way out.

Holden may be able to run a Tech2 scanner on the car to see if it's logged any errors.

BCM? We also have a crappy Suzuki Vitara that has a dodgy door loom connector on the drivers door which rattles loose every so often. When it comes loose, the central locking does what you are experiencing and the power windows also stop working on all 4 doors.
