I am frustrated.... wiper blades for s

Just polish your windshield.
Also keep your speed over 75mph and you don’t need those wipers!

 

Bosch blades are the best I've ever used, and I've tried alot of em

 

Take your blades off the truck and measure them. Or take into store and hold a new one next to the old one. Then look on package and it will say what size it is. As far as buying them, get them anywhere blades are sold. Now other will disagree but I don't spend money on winter brand blades. Imho there not worth the extra money, don' last longer or do a better job. I also always buy at least three blades. That way I have a replacement for when needed. Cause it always seems one goes bad before the other and when I need it most.

 

I've switched my Cascadia fleet to 22" Anco Contour blades. No metal, hugs the glass, sheds ice and snow.

 

HA. I remember the old air driven wipers that were nothing but strips of rubber on metal. Once the temp freezes just so out of the air, they get stuck and quit working. (The airlines that is.. driving them)

All you can do is prior to hitting a winter front in a storm that is coming for you is begin to shift your heat and apply it all to the glass itself. Nothing else. Fire up your heated mirrors and whatever else. You want them to be warm when you do hit it.

One possibility is Rain X that has a layer that you can apply versus ice but I don't think that is too common. Another is heated wipers. But once they Ice over at a end of a blade it will work under and add to itself until it's no good to you.

You can only do so much. Nature has a way of defeating even the best engineering if there is any at all.

 

You have to understand. The reason your blades aren't wiping the windshield clean is because it can no longer conform to the changing curvature of the windshield. The reason it can't is because ice is building on the BLADE and ARM, freezing it into a malformed shape. It's not that ice is forming on the windshield. Shorter blades are less prone to flex and "lift" and become frozen into [deformed] place. Heating the windshield is not going to warm the blade and arm enough to keep wet snow from freezing and accumulating there.

Try running blades 2-4 inches shorter than the recommended length in winter months.
A 22 inch blade bought at a truck place is the same as a 22 inch blade bought at Walmart or Autozone.

Try pre-spraying the arms/blades with Prestone Windshield Deicer soon before you expect wet snow. Also spray the foreword radar cover if you have one. Wet snow is prone to occur [and accumulate on vehicle surfaces] anywhere between about 28-33 degrees F

 

Had a KW T800 daycab for much of last winter.

I also had my left arm stuck out the window with a sturdy pen so I could lift the blade and smack it off the windshield to de-ice it when it reached me.... sucked.

 

Volvo actually makes a electric heater windshield option and it's not terribly expensive.

 

That is one of my buttons.

Fleet buyers never spend a dime more than they have to. if I was a buyer... the money bags would weep, but the drivers would be joyous going into winter with the best available if I had anything to say about it.
