Thanks for the info! Definitely not spending several hundred $ to fix a 60 second noise and then it stops.

My 07 Impala's message center keeps flashing that the trunk is open. It started several weeks ago & yes the trunk is closed lol. Could this be a fuse that needs replacing?

You can find information on your vehicle's electrical system (including diagrams of fuse blocks) starting on page 397 in your owner's manual. If we can be of any assistance, please let us know!

I just recently discovered this knocking sound in my 2008 Chevy Impala, I was told by a friend that this is something she heard in a similar car. Is this something that I can fix or is it best to have a mechanic do it? its started to get louder and sounds like now its in the venting and the dashboard! Help!

My 2006 does it, but it has gotten worse. Now it won't stop unless i turn the car off and it takes about 5 minutes before it does stop. And only HOT air blows out of my driver's side vents.
