Oops, turns out I don't have those wipers (don't know why I thought I did). I have Trico blades. When I first had to have the blades replaced, the new ones didn't match the curve of the windshield glass, so I had to have the mechanic change them again. The Trico ones fit very well, so I kept the packaging and this time, when I noticed the greasy quality on the windshield, just went to the auto parts store, bought the same ones and they installed them for me.
It won't shock me, though, if these have to be replaced in 2 years, too. If Bosch makes blades that fit my car, hopefully I'll remember this thread and check 'em out. Thanks, Dee!
