air condition system was putting refrigerant into cab over the summer making us sick. We could not tell ,because there was no smell. I was in car with a/c on and got a blast of refrigerant in my face were in I almost pasted out. I turned of a/c and opened windows. My being a retired mechanic helped me to control the situation, but average person probably would have passed out and recked the car. I was treated for exposer to a chemical and my wife was too. I can not tell if a/c is fixed, as there is no smell or visibale way to tell.08
