Hi Priuschat, I changed out my spark plugs this weekend and I put everything back together. The only problem is that I think my wiper blades are no longer in alignment. Is there a guide as to how set these wiper blades? I tried looking for wiper alignment. videos on Youtube, but there is none for the Prius. Surprisingly all of the spark plug guides I looked at didn't mention to take into consideration wiper alignment.
When the wiper blades are parked, the far end of the wiper blade will be pointed at a "dot" on the inside of the windshield. Look at the area around the far ends of the wiper blade to find the "dots" Its nice to torque down the retaining nuts.

In the future, put some blue, or green, painter tape on the inside of the windshield along where the blade sits. Then you'll know where to set them too. I set them more or less level.... P.S. I meant the drivers side. Passenger side won't be level. But curioisity got me and went and checked. I never knew about the dots! And there they were! NIFTY! Thanks for the information! Drivers wiper was dead on, passenger is probably one slot lower. Close enough.
Pasting from an older thread: Remove the two pivot nuts and lift the wiper arm off both pivots, carefully, straight up. [ok, the older post was about the passenger wiper, the one that has two pivot nuts. For the driver side, same deal, but just one pivot nut.] Use a brass bristle brush up and down (with the direction of the splines) to clean out the splines on the shafts (protruding from the car) and the holes in the wiper arm. Line up the arm (not pressing at all down onto the shafts yet) so that the tip of the wiper is at the small round dot that marks the park position of the Toyota windshield. (If you have a replacement non-Toyota windshield that doesn't have the dot, you're on your own.) When lined up, press carefully straight down onto the shafts, paying attention to feeling it onto the nearest matching splines. Hold the arm from moving, and tighten both nuts to the specified torque without letting the arm move on the shafts. The italicized be-careful-here parts are because the shaft splines are very shallow and fine, and easy to smush flat if you let the arm twist on the shaft. Other than that, it's all easy.
The driver side wiper has two dots. An upper one and a lower one. The passenger side wiper only has one dot near the edge of windshield. I wonder who the wiper arm on the passenger side works as wiper attachment arms have no spindles. I guess it works off friction. The driver's side has spindles on both connecting parts.
Those dots are minuscule; I had to exercise my full myopic super power to spit them. They are there. @ASRDogman’s tip about a bit of tape is what i do.
