If message center lights stay on overnight, can they drain the battery? I have an 02 Impala and twice in the last 3 months I have had a dead battery in the morning. The only thing that I can find that was possibly on was a message center light. After a boost the battery is fine. Thanks for your help!

 

It is possible. I had an 08 with the same problem, except it was the radio.

 

Yes, the message center can drain a battery. Read this post on how to diagnose battery drain.
