I cannot for the life of my install these things. I got the front drivers side on but then window wouldn't close so I took them off. I followed instructions to a T. Does anyone have them installed and could take pictures. Edit: I haven't even attempted the read installation. I don't know how I feel about peeling back the weather stripping. P.S. 2014 Prius Two
You need to give the visors some time to bed in the channel. Just close the window slowly in manual until it will eventually close in auto. It took about a week before mine would close in auto every time. The back ones can be difficult. There is a website listed in the instructions that has a very good video with excellent installation procedure. The weatherstripping will pop right out and pop back in after installing the clips. I needed the video to understand the proper installation of the rear clips.
I choose the easy way few Prii back, since early 2005 and went with the outside door frame installation, it does look awesome.
The visors do look good on the Pri, whether inside or outside. They look OEM. I just prefer the inside channel. YMMV.
I tried for hours until I watch this video at installation section 2014 Toyota Prius | WeatherTech Side Window Deflectors, Rain Guards, Wind Deflectors | WeatherTech.com
I had some difficulty with my gen 2 as well and eventually figured out the tricks and posted here: WeatherTech window deflector install tips with diagrams | PriusChat
