Just wondering if anyone out there is having a problem with their in-channel deflectors preventing the windows from rolling up. I asked about them at my local parts dept today, and the tech strongly recommended I not get in-channels. He said that Nissan vehicles are notorious for in-channels preventing the power windows from rolling up, by engaging the safety feature which apparently automatically rolls the windows back down when hitting an obstruction (e.g., kiddie fingers). The salesman concurred stating that he had a similar problem with an Altima. I've read a couple of comments about them initially preventing the window from easily closing, but have not seen anyone stating they got rid of them because they were consistently preventing normal window operation.
