Could anyone tell me what size wiper blades I need for the front and rear? I was going to grab some on Amazon but it's not clear which ones will work. Thanks a lot!
Gen II Prius Wiper Lengths Driver Side 26 inches Passenger Side 18 inches Rear Blade 16 inches IMO, the best blade for the rear is the one you get at Toyota. Very easy to change. Get the guy at the parts counter to show you how to swap it. Once you have seen it done, you will see what I am talking about. Cost is NOT real expensive for the OEM part. I replaced the rear one last year and it is still good today. Change blades once a year here, but the rear one I am going to go two years on it. 2006 Toyota Prius Parts - AutoNation Toyota Gulf Freeway Parts For the front blades, buy the aftermarket brand you like. Just get the lengths called out above. Best of luck to you and I hope the info helps you!
Also, if you still the OEM blades on the front, you could order the refill for them. Less than $10 from Toyota if you just replace the blade itself. 2006 Toyota Prius Parts - AutoNation Toyota Gulf Freeway Parts
Here's a video that shows the blade removal and installation for the rear. There is more than one type of blade in the above video, the video part you are interested in would be the one they refer to as "Type A". Note how they remove the U shaped piece of plastic and then pivot the arm up prior to removing the blade. Same procedure on the Prius! I don't use the above brand. The video is just to give you an idea of how easy it is to change the rear blade on the Prius.
I'd highly recommend PIAA silicone blades from Amazon. There are several types of PIAA blades, just get one of the silicone rubber ones. Silicone blades have two advantages: Long life. I typically have gotten 3-4 years out of my silicone blades and I've used them in all my cars for the past ~10 years or so. Glass treatment. If you're familiar with what Rain-X does, silicone blades do the same thing as they are used. The glass is treated with a coating that makes the water bead and run off the windshield. Huge improvement in visibility as you can see between the droplets instead of trying to look through a film of water. The big downside is cost at $20-$30 each. However, since the blades last 3-4 times as long, the cost isn't actually more in the long run. Even if it were, the improvement in visibility is worth it in my view. My Prius had new blades from the dealer when we bought it in the fall, but silicone blades are going on this spring.
