A thechnical question

[Walking Eagle]

After many years of driving and thinking of this problem does anyone know ?
I picked up truck today from shop where it had been for minor stuff. Was real light rain. Now I noticed again the drivers wiper streaks but the passengers side is real clear.
Anyone have a reason that this always happens. (Always change both wipers and have even, over the years, swapped them, and it is only the drivers side that streaks
Should I move the pedals to the right seat ??

Odds are your wiper arm is bent. Either it is not putting enough pressure on the windshield, or it is ****ed to one side.

I had that problem too and i hated it, it's calcium deposits on the glass, it can build up, it's really thin so it's not very noticeable when you look through the glass, but look closely at the glass, it's there, when the glass is wet the water smears because those deposits prevent the wiper from swiping the glass clean. cleaning the glass with a razor blade and water will take the deposits off easily.

This has been over the past 40+ years and I duno how many trucks the drivers side always streaks before the passengers side

it's because you look out that side more and it wears the glass out

Sounds reasonable...
BTW Cleaning blades with alcohol, helps...sometimes.

I thought that's why they made the seats adjustable.

I agree, Walking Eagle. Every truck I have driven in 26 years has had a great windshield washer....on the passenger side.

I think its called Murphy's law, it also happens when rocks hit the glass, they only hit where your line of site is

yep.. just like when a bird ****s on your windshield. always on the drivers side & right on your sight line.

I dont know about cleaning with a razor blade... wouldnt that cut into the plastic safety film installed over windshields ?

the plastic film is in the middle, two plates of glass are tempered sandwiching the film, when the glass breaks it sticks to the film in small chunks thats where the tint film is, in the middle of the tempered glass plates on the top edge of the windshield.

I have the same issue. Last two trucks. Drivers side faulty. I think little gremlins screw with the drivers side wiper before truck comes out of factory.
I also look out the drivers side alot. It must be worn out.

I have a theory. When the drivers side wiper clears that side of the glass the water goes off the windshield and down the drivers side window. When the passenger side clears its side of the glass it brings the water to the center of the window and the wind spreads it back across that side of the glass. Therefore that side of the glass stays wetter longer and that wiper lasts longer.

My theory is we spend most of our time in the right lane, others pass us in the left lane spewing more gunk on the left wiper. I just came up with it and I think I am brilliant

you are a legend in your own mind!

Not on my KW, the right side throws the water out the right side, the left side throws it left.

Nope, I spend most of my time in the left lane.

I'd have to agree with ya there.

I just want to let you guys know, I just bought those pressure springs you put on your wipers to keep em jammed against the window. I,ll let you know how they work, after a trip upstate in the snowy weather. That will be a good test for them.

Almost right. Yes the plastic is in the middle but the glass is not tempered. Two pieces of regular glass with plastic in the middle is laminated. Thats why when you get a rock chip that cracks the crack runs. If they were tempered they would shatter into tiny pieces like a side window.Some older cars had tempered windshield (60's and earlier) but they have not made them that way for a long time.
