We just had the drivers and passenger (door) slider windows replaced. The driver's slider was collecting water between the panes. I could have put gold fish in there.....Anyways, these two windows lost their seal and were badly fogged up (common with these windows). I arranged for the local glass company, came to my house and replaced both sealed slider windows with a 1/4" laminate glass.... it is tinted too and cost 189.90. I know its not DOT but.......
