This morning as I'm taking a short trip from an appointment to my home, I tried to roll my windows down. Nothing happened. About 10 minutes into my drive, a light came on that said "WINDOWS ON". This allowed me to roll down my windows and enjoy the breeze. This evening, I went to roll up my windows and now they won't go up. Did I hit a button somewhere on my car that permits me to "turn my windows off" or "turn my windows on?"

When I bought the car, there was no owner's manual with it, so I'm puzzed about what the deal is. Can anyone give me some tips?

Thanks.
