I'm trying to figure whether this is normal or not... The rear wiper fluid on my CX7 doesn't spray out. It just kinda runs down a path about 3" wide. The wiper picks it up, but I can't imagine it's supposed to do that. The other day it was iced up a little and I got a nice spray, for a few seconds, then back to the old way. Is it supposed to spray/fan out across the rear glass or just pour down?
