Mr./Ms. Intruder,
You can put a small dab of silicone grease on the stainless steel shaft which pushes the blade out in the corners of the windshield. The best way to do this is to pry up the plastic cover over the shaft, and do it when the wiper is at 45 degrees up from the resting position (by using the ignition key to run the wiper motor while the wiper switch is on.) You'll see that the shaft is out maximally when the wiper is positioned in the corners . . .

There MAY be a way to open up the big plastic cover which covers up the gears, but I haven't figured out how to do it. I'll be very interested to see if anyone else knows how to do that.
