Once the A/C is used in the summer and then the truck is parked. Then on the next use of the A/C a horrible smell(like mold) comes from the vents. This is no joke since it has caused sinus infections for both me and my son. Because I take medication for Arthritis that lowers my immune system, I was sick for over three months. No, I'm not an idiot. Once I got a wiff of the smell, I turned the A/C off and opened the windows. But have you ever known as soon as some exposure happens that you are sick. Well, I knew immediately when it happened to me that I was going to get sick in some way. Yes, I get exposed to all sorts of things that people are exposed to in stores and at work. But I got sick from the A/C in my truck. I felt it happen. I would really like someone to post the type of solution that Dodge sells to remedy this situation.
