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.

Good evening luckygirl7133,
 
We're sorry to hear that you're having some troubles with your HVAC system; what are your plans for getting this looked into?
