The rear window demister button in my vs seems to just fall out =\ i got it the other day and yeah, went to turn the rear window demister on, (which doesnt bloody work, the orange led comes on, i hear a little 'click' noise behind the dash, and it doesnt unfog my back window, and the connectors on the back window are still connected to that copper like strip) but yeah, it just falls out of place, i cant relocate it back in any ideas?
i had the same problem, i just went to the wreckers and got a new button out of another VS, put it in and it hasnt moved since.
Grab a whole new switch. You can pick them up off ebay in great condition for about $5. Otherwise holden do them for about $20. You can repair them but you will usually find they will fail again.
