Passenger power door lock constantly failing

[David Macca]

Hi I have read the other threads.
Replaced the actuator multiple times.
Replaced bcm and reset multiple times.
Replaced wiring harness in the passenger door.
Last time Southport commodore Replaced all the door locks after it went into full lockdown including replacement of both key fobs.
Is there anything else someone has found to fix this reoccurring problem.
Thanks David
Ps it is a 2004 vy wagon with factory LPG if that makes any difference

That is an interesting fault !,

I was going to say replace the door relays in the BCM.

If they replaced the BCM, did they link the BCM ?,
(As that is a must for all module replacements)

Did they Reprogram the Keys in Correctly
If the above items where not done correctly, you have multiple faults that is the cause of it faulting.

Get a 10mm syringe from a chemist and get a straw that screws onto the end. Fill the syringe with silicone paste/grease. Repco sell it for about $30 in a tube. It’s used for a lot of things. Maccas use it on their soft serve machines, plumbers use it on taps, it can be used on the guide pins on brake callipers and it solved lock problems on one of my VZ’s.

In each lock assembly, get the silicone paste right into every gap, and pivot you can see. Squirt it in. Lubricate the assemblies with silicone paste like a vets hand.
