I got new blades at my 1yr service back in Sept, after noticing The Streak right in the middle of the driver's side of windshield for a long while.
Since then, The Streak has returned -- occasionally. It's weird. We just had a lot of rain in CA, and it worked well in the rain. It's when the windshield gets dirty during dry periods, or, say, some bozo ahead of me turns their wiper washers on and the spray hits my windshield and I have to turn my washers on, do I occasionally still get The Streak. But it's not enough of an annoyance to bring it back to service (who no doubt is reading this... always spooked by that but this is the post-Snowden era after all...)
