This just started happening this past weekend. The car wasn't doing this prior to that. Here are the details.

When I turn off the car and open the door, the car starts doing "ding ding ding ding" audible alerts about once per second until I shut the door. I had other cars (not Corvettes) do that if you open the door with the ignition switched off and the headlights are turned on to warn you so you will turn off the headlights before the battery goes dead. That was my first thought when I heard it in my C6 but my headlamp switch was in the Auto position like I almost always have it and the headlamps were not on.

Does anyone have any idea why it started doing this all of a sudden? It may be coincidence, but maybe not so I'll mention it. Just a few minutes before it started doing this, my wife was adjusting the sun visor on the passenger side when the post on the right side of the visor fell right out of the housing and was kind of dangling there in my wife's hands with all the wires hanging down that power the vanity mirror etc. She was able to push the post back up into the housing and pushed the flat plate back up flush with the bottom of the housing. (I'm not sure the visor is really "fixed." Seems like a poor, cheap-o design to me). Shortly after that when we stopped and I opened my door, the dinging started.

Any suggestions would be helpful.
