Nobody seems to mention it, clean the glass and blade with rubbing alcohol or isopropyl alcohol
You get a lot of grime oily crud on the glass especially if you do lots of highway driving

I am not a fan of the glass treatment on the windshield probably because 95% of my driving is highway speed and find if I run the wipers it leaves a steak trail behind the wiper

Love the treatment on side and rear tinted glass
I find with dark tint at night add rain the less water on the glass the better

Yes on the cleaning the blades. Interesting note to that. The wet wipes that you get from lets say, buffalo wild wings, work REALLY well for cleaning wiper blades.

yea I am guilty of using alcohol wipes from my works first aid box haha, also guilty for cleaning my blades while working (i work outside)

Will this advertiser masquerading as a poster address my problem product?

He gave you two replies already. Sorry if you didn't like them. He is not 'masquerading' as anything. He is both an advertiser and a poster.

Maybe as an advertising member of this blazer site he could pass the word upstairs to design that there could possibly be a problem with the drivers wiper having too much curve for a blazer windshield. Or he could suggest it is a user problem.

Since the S-series is a dead model and has not been made in 9 years, I doubt that anybody at GM would care.

Could it be that the plastic used in the foil of the blade expands when exposed to sunlight, as the problem blade worked for the first two weeks. And the additional curve is a benifit to the pass side. IDK

I've had nothing but problems with any blade on my 99 mini Jimmy. They all seem to streak.
But, then I tried the Trico Exact Fit, and now every thing is clear.

Easy fix, flip flop the driver and passenger blade. who cares if the poassenger sie is a little streaky. IMO
