911 windshield wipers?

Can't hurt, though it won't help much for in-town (low-speed) driving.
I'll see if I can find something like that.

Any other suggestions? Didn't Porsche have something to address this, or
did they just let all their owners drive blind in rain & snow!?

I have forgotten the structure of the older wiper assembly's, so I am
shooting from the hip here.

When the car is at rest, pull the wipers up off of the glass, to reduce
the effects of the problem. You might already be doing this. Or put
two wooden dowels (or flat chunks of wood) under each end to reverse the
flex while parked.

Can you possibly bend the wiper arm slightly to take the pressure off of
the middle portion of the wiper at rest? Or buy another arm to (maybe
heat it) bend it.

What type of blade are you buying? Is there another brand that has a
stiffer blade support to prevent the bow from occurring?

Can you reinforce the blade itself? Possibly a pain, but might be worth
trying.

I remember a hack to change the wipers over to a right-rested position,
rather than left. It requires some effort with changing around the
motor, but this may be another (pain in the a$$) option.

Keep us posted.

Well, that would undoubtedly help, but the hassle factor makes it
unlikely to be implemented.

You could, but if you reduce the pressure on the arm at rest, you also
reduce the pressure in use -- which means it isn't going to press the
wiper against the glass very well. Not good.

Don't know on those.

Hm, I don't see how that would work. Either you leave the wiper pivot
points where they are, meaning the blades are in the middle of the
windshield all the time, or you move the wiper pivot points to a
different spot. That would require body work and other na$$ties.

Creative ideas, but I don't think they will work for her...

Thanks,

I didn't mean to imply reducing overall pressure, but rather altering
the angle of the pressure to better suit the rested position.

Hey, I am just here to run my crazy brain and just maybe something will
help. I don't ever remember having this problem with my 79, so
LowLife's question about windscreen replacement seems appropriate.

I am quite sure you misunderstood my suggestion about the wiper arm
reversal, so here is an article about it:

A three beer rating. Doesn't seem so bad.

have you ever had the wind screen replaced? are you the original owner?
reason I'm asking is it sounds like what I experienced after the wind screen
(wind shield) was replaced on our Jeep Cherokee. They had to remove the
wiper arm and when they replaced it they did a poor job and it would crash
into the cowling. Took a bit of fiddling but I got it right eventually.

Not original owner (only about 7 yrs), not sure about replacement. But I
don't think we're seeing the problem you have. The wipers seem to go where
they should, but in the park position the left wiper hangs off the left
curved part of the windshield.

Hm, you are right, I did. That does look promising. I didn't realize they
would reverse so nicely. I think I'll look into that. Thanks!
