I recently purchased a used 2006 Honda Civic and have had some issues with the a/c. Last night I turned it on full blast and air was barely coming out. Turned it on this morning on my way to work and the a/c performed perfectly. Just wondering if anyone has any idea why one day it struggles to push out air and the next day it's perfectly fine

I sounds as if the "doors" inside the vents and tubing may have been stuck from sitting. By turning it on then turning it back off, when you turned in on the next day, they had loosened up. Just keep an eye on it. If they hang up again, there could be a vacuum problem that controls these "doors'
