Thanks ZX, I hope that's the fix for me. I'm dropping it off on Tuesday for Inspection etc. I'll let everyone know if it does the trick.

 

ZX you are the man. There was a post here a few weeks ago requesting this exact solution. Glad you are here.

 

I'm curious as to what the correct spray pattern is. Mine puts two streams on, one about 1/4 of the way up and the other about 1/2 way up. That leaves the outer part of the sweep dry unless you really use a lot of fluid.

Does this seem correct?

 

Agree with shark. I do not get any juice on all parts of my windshield, but I dont think it is an issue. That is just the design isnt it?

 

Yeah, my post regarding this a few weeks back was for an ineffective spray pattern. I don't think anything is broken but like 73shark, my pattern sprays too low. Really wondering if this will fix this condition. Thanks

 

I don't think our spray pattern is caused by a damaged hose because it squirts out like a fire hose. Really goes thru the fluid. Just wish it got a little higher on the windshield. I do prefer the wet arm system over a fixed nozzle. Pretty much insensitive to speed.

 

If your washer(s) does not provide a stream of solution that fully cleans the area of blade/windshield contact then this is the fix.

If the fluid sprays hard but does not hit the right spot this still may solve the problem.
