Re: my Falcon AU central lock not working
The repair is to remover the door lock and have a look to see if the plastic arm which is activated but the inside door handle is making contact properly with the small arm, I found that there is a small spring which somehow had wound its way over this lever and used long nise pliers to wind the sping back to its correct location, this has fixed the exact same problem you have.
However I do think this is a temporary fix just looking at things, but hey on a Saturday and Sunday the wreckers are not always open.
I couldn't work out where the door light swich is so perhaps it is built into the door lock. ?
