I bought the AVS in channel, Installed them and was very pleased..... then the next morning both rear window deflectors where bowed in and touching the windows, if i rolled the window down they bowed further requiring me to push the center outward to roll the window up. I then rolled up some micro-fiber towels and wedged them in between the deflectors and the windows and they took the original shape back.... 12 hours later bowed inward, customer support believes the installation of some additional clips should resolve the problem so I am awaiting receipt of those. If the clips do not resolve the issue I will be returning them, I have a 2000 silverado with weathertech deflectors on it since 2 weeks old and not a single problem with them in nearly 19 years as well as 3 other previous vehicles all weathertech no issues, I only bough AVS because weathertech is not selling them for the DT yet.
