[s-cars] Auto Check System & door/lights chime

[Robert Rossato]

Thanks Stott.  Seems to confirm that the Auto Check system and door
chime are tied to the same speaker.  I thought there was a separate
relay with a speaker for the door chime.  Maybe that's the seatbelt one?
I know there's something back there behind the IC.

Fred - Any luck finding a suitable speaker?

At least I have a spare S6 IC that I can cannibalize, assuming that one
has a working speaker.

Bob

P.S. Not sure why your messages aren't getting through to the list.  May
want to unsub and resub.  Seems to fix things sometimes.  Though I tried
to send my original message yesterday and it got bounced back as spam.
Had to send from my old account.
