Low-beam problems

I have two problems. First, at night only when I am using my lo-beams, if I use my turn signal my high-beams will turn on and I have to wait until I turn to flip my high-beams on and off to get them to stop. Could this be a bad signal stalk? Secondly, as of two nights ago my low-beams stopped working altogether so I am stuck using my high-beams. Could this also be symptoms of a bad signal stalk considering my dimmer switch is located on the stalk?
