Air Conditioner Problems of Buick Lucerne

I was stopped with engine running and air conditioner fan on high. I turned the wipers on to clean windshield. Immediately I was overcome with extreme burning in my eyes I could not open them. I reached for door handle and got out. I was in a panic, having no idea what happened. I asked 2 people for help,the second person came to my car and we searched car for something burning and found nothing. I was afraid to get back into my car. I have never experienced a burning in my eyes as this. I felt helpless because no one witnessed this freak incident. Finally I used wet paper towels and covered all the ac vents and drove home in fear that it was going to happen again. There is no doubt what so ever if I was driving when this happened I would of crashed. I could not see. When tubing broke the fluid landed on a hot engine paet and the water evaporated and the methanol vapors came through the ac vents directly into my face. The Buick dealer didnt mention or discuss this plastic tubing be replaced. He just put a piece of rubber to hold the ends of broken plastic tubing. Im very uncomfortable using wipers now because as I mentioned if it were to happen while driving I might as wellbe blind. I want to know if the tubing is not suppose to ever break and more so, why did it come through the ac vents that was on high. ?.
