Hissing when I turn the A/C off...........
I was just wondering if this happened in anyone elses car. I'll be driving around with the a/c on and when I get to where I'm going, I'll turn off my car and turn off the a/c. Right when I pull the switch over it kind of hisses a little then stops. What could this be?

What you are hearing is the engine vacuum opening & closing of ac/heat doors.
That's why it is normal. All cars (atleast the GM ones) sound like that.
