After having watched several YouTube videos on the installation of these side window deflectors it appeared pretty simple. Well that wasn't the case. I managed to break one rear and one front deflector on opposite sides of the vehicle. They simply would not go all the way up into the window channel no matter how I "gently pulled out slightly and applied upward pressure". I did manage to salvage the broken front deflector by carving out the shattered plastic but the busted plastic on the rear one was hopeless no matter how much plastic I remove or where I moved the silly little metal clips which hold the deflector in place.
