Air flow from the dash vents may be incorrect due to a damaged engine vacuum hose near the battery tray.

In replacing the battery, a vacuum line between the battery and strut tower was found split open. I capped off the end sucking air and the air ducts don't change when driving up hill and you lose engine vacuum.
When driving during the summer time I did not have air conditioning it just blew hot air through the vents. Though it blew air out, it didnt come out of the right vents and when im done driving and get out, something smells like its burning.
