Question about 2005 Lexus Gs 300
Your door lock actuator is malfunctioning.
Since yours is a coupe your going to have to unbolt the window from the regulator, remove the 2 10mms on the left side of the door and pull that side of the regulator out of the way. then there are 3 T30 to-rx by the door latch that you need to remove, a cable that you pull off that connects your exterior door handle to the lock actuator and unplug the actuator. Then you can shimmy it out. The door pin and cables that attaches to the inside door handle need to be switched over to the new one.
Also if you have front side airbags they have to come off, but remember DO NOT turn the key on while the air bag is unplugged or you will have an airbag light that will have to be cleared. Also don't have the key on while you plug the airbag in or it supposedly goes off in your face, or so im told.

sorry not sure the 12v prob will help this swtich works on 5v off 3v unlock 1v lock single wire lock/unlock logic signals
I found wiring diagrams at
it is 2004 but use the wiring diagrams to test the wires
(most likely to fail where they flex)
because it is using logic gates disconnect the plug at each end of the wire you are testing or the damn thing will find a few diffrent ways to trick you.
