Sometime ago I had a problem with the airbag indicator light coming on and staying on. I took it to the dealer and they didn't know why and could find no cause so he finally called GM and they told him what to do to reset it. I was told when the battery voltage gets below a certain point, from sitting for a long time, the airbag sets the indicator on and to reset it you do something very simple like disconnect the battery for a while. The car hasn't been driven for sometime and this has happened again and I disconnected the battery for overnight and it didn't reset. My contact at the dealer is out for the week. Can anyone help me get it reset?
