Airflow only coming out of defrost area. Was working fine until I was tightening a loose ground connection from battery to engine. Sparks flew, didn't take positive post loose(duH). After that was when the problem started.I think it must be a fuse but owner's manuel doesn't list one.

Do you
have the same problem?
