After being inspired by Dennis Knighton, who was advised by Alan at ptworkshop.com.au.

I got off my butt and fixed mine as well.

Remove all the plastic on the inside of the Lift Gate.

Unclip, in my case, the Red and Black wire connector.

Using a screw driver short out the 2 connectors on the clip (not the clip with the Red & Black wires)

You should hear the lock actuator move. (If not make sure the doors are unlocked and try again)

If you hear a noise proceed as per the photos, if not it is maybe the actuator!

ps got the switch from Jaycar

Well described Michael , but you didn`t include my blue language .
Just a bit fiddly but easy for others to follow your instructions .
Thank you

Great Australia Day Weekend post!
Wombat, a Platypus.
So did the switch cost .20cents.
Only joking.
Good post Michael with the added captions. Well done. Very helpful to those in need.
