Sorry if i missed a thread about this but i could not find one. I have a 2010 aveo and my air conditioner only blows when i have it on setting one until yesterday it also worked on setting four but now that one does nothing either whe i have it on one it blows cold air perfect but on any other setting nothing comes out of the vents its as if i turened it off. Any ideas what may be causeing the problem and how much it may cost to fix. Thanks in advance for your help. And sorry for any errors in my post im typeing on my phone. Thanks.
