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.

RE: TSB (fix) for poor windshield washer spray pattern
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?

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.

RE: TSB (fix) for poor windshield washer spray pattern
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.
