The wiper blade size should be 20" for the passenger and 22" for the driver's side.
Always adjust wipers in "Winter" setting.
For me, I just leave them in the winter setting all the time. In the summer setting they need to switch to "winter" to work, and then go back to the summer setting. Seems like more wear and tear on the linkage to me... so I just leave in winter all the time.
