Asymmetrical windshield wipers

And when you see an '02 without any wiper spoilers, or with two, or with one installed on the passenger side, you can shake your head in disbelief and mutter "Newbie"!

 

Two spoiler wipers are just better.  Bean-counters be damned!

I have a theory:  The deflector is there to create an air flow up and over the windshield at speed.  The air flow provides some deflection of incoming bugs or other small objects.  If this is the case, it is needed in front of the driver.  Let the cost accountant sits on the passenger side.

 

Hmm, how to test this theory?

 

It is smoke bomb season, with the fOurth just around the corner.

Fireworks are legal here in the Evergrun State, (at least on the reserVations).

 

Please hang one on each side, in front of your hood.

Then take a test drive, to compare the wipers with/without. 

The world is your wind tunnel.

I wanna see the movie !

I, for one,  I am not going to place it on the passenger side.  The last thing I need is my wife freaking out and telling me how to drive  when I am going 100mph on  a rainy day.  It is like putting those blind folds on horses....they don/t get spooked....and no I did not compare my wife to a horse.

They used to sell aftermarket ones made of plastic in the UK to clip on. They are supposed to push the wipers onto the screen at speed. The manufacturer maintained that aerodynamic forces were lifting your wipers.

Starting from zero, the driver's wiper moves from the center sidewards. The passenger's wiper moves from the side to the center. So they run through different air flows and the one needs a deflector, the other one doesn't.

Here we have the plemplem wipers of a Morrceidiiiees Beeenz:

Symmetric motion. Symmetric air flow. Same wiper design. Won't score 100mph- no deflectors needed.

On RHD cars, it's the opposite.  The passenger's wiper moves from the center sidewards;  The driver's wiper moves from the side to the center.   With some exceptions, the air deflector is on the driver side.

So I don't believe there are mirrored wipers (and motors and linkages) for RHD cars.

I can attest to the relative uselessness of 2002 wipers, deflector or no,

much over 90mph when you're in the middle of the starting lap furball with about 30 other

cars, all on race rubber...

 

ya can't see shit.

Hen,

 

Once again, you're making trouble!  And yet again, you're using facts!  Most of us prefer to develop our opinions based on....guesses.  But good solid guesses! ?

 

Seriously, however, the parts drawings are not always updated for the nuance of parts application.  Do the actual part numbers reflect that Euro LHD = Euro RHD?

 

Best regards,

 

Steve

To be fair, we can't expect people in the past to have looked at the spoiler on the passenger wiper and not thought 'surely that should be on the Driver's side'?

 

perhaps they came from the factory on the left but people moved them to the right?

 

John's car may be the closest thing to a stock RHD that you can see anywhere.

Yeah I always thought that the left wiper is exposed at speed to the same force that will lift your hood if you don't latch it and with out the spoiler at speed will not wipe the bottom of the windshield.where the right side wiper that air flow just spills of the side of the car.

My 83 911 is much faster than the 2002tii.....I see no deflector on the wiper.  I think BMW could have saved a few more pennies and eliminated the deflectors...

Me making trou-...   But...   Steve, I just...

Maybe I better should have declared the post with the Benz as an also-guess more clearly. And to give the discussion some balance I thought I could offer some alternative facts.

I compared a certain number of parts numbers and didn't find a difference between Euro LHD and RHD. And it would be well-known if there were, I think.

Please consider it as a theory, too. Or a look for *wheresthetruth*. A may-bee, even if it's july.

The subject made me think of last week putting new on wiper blades I found there to be two different lengths of blades on my one car. The one with the deflector took a 16" while the passenger side can only take a 14". I don't remember this to be normal, but vaguely remember cutting down the passenger side blade to fit years ago. Maybe the arm with the deflector or the stainless wiper blade holder is from a larger model bmw?
