How to adjust windshield sprinkler in accord 2004

I have etched a couple of windshields because the blades started moving
before the stream wet enough of the glass. Sometime around the mid 90's
they started keeping the wipers down until the sprayers worked for a second
or two.

One question no one has asked yet: Do you know for sure that the offending
wiper blade is actually parking where it should? It could be out of
adjustment (usually happens when somebody tries to use the wipers in the
winter when they are iced over & frozen to the glass). If you have access
to an FSM, the distance from the bottom of the windshield to the blade when
its parked is usually in there. If not, look for other similar cars and see
how yours compares.

 

It's not that bad. The long size fits on both sides, giving me a little
more view of the world. ;-)

 

If the spray hits the wiper blade, the glass will get wet, at least
around here.

 

More preciselly, spray hits the wiper arm, not the blade itself.
No water hits the glass when wiper is resting parked.
All water hits the wiper arm and flows down to the throf.

 

This is exactly what I am talking about.

No, I have no access to the factory service manual...

 

Chevy used to have "cowl induction" where the downforce pushed air into the
carburetor from the base of the windshield.

The air intake for your cabin heater is at the base of the windshield.

Some windshield wipers have airfoils to harness the downforce.

Bottom of the windshield is considered a "high pressure" area.

 

That's wrong.
Nozzle needs adjustment.
Fluid should hit the glass about 2/3 the way up.

 

Please read the beginning of this thread...

I have already written any better adjustment is not possible.
If I move nozzle up the way water barely touches the wiper arm
than the majority of the water spray hits the upper edge of
the windshield. The wiper arm is simply in the way and there
seem to be nothing I can do with the nozzle to avoid hitting it.

When you sit high in the driver seat you clearly see that
the driver wiper arm sticks much higher over the edge of
the hood than the passenger one. But the wiper is parked
below blackened part of the windshield, so it seems to be
in the correct position.

 

That is exactly right for use at highway speed.
Stop work.

 

I have been reading this thread from the beginning, but still confused
about the problem. When I turn on the spray on our '03 Accord, the
wipers start immediately, so there is no problem of the spray hitting
the wiper blades except occassionally as they wipe.

 

On my 2004 model there is a delay, maybe 1/2 maybe a second,
I have not measured it. This delay is enough to press the lever
for the water and depress it BEFORE wipers get activated.
So the delay, while short, is significant and the first movement
of the driver side wiper happened when the glass is stil dry.

When you continue spraying water while wipers are moving
then the glass is hit with water and there is no problem...
But when you have a lot of dust/sand on the windshield and
you start the wipers dry you can etch the glass pretty easily
with a single move of the dry wiper.
