Tried the rear washer for the first time today. I just got 2 streams running down the windshield. Is that all there is? Or do the jets need adjustment? I assume it's supposed to actually spray the window.
I get the 2 streams too I was actually worried that the hose might be kinked somewhere in there. It happened to my neighbor on his 2001 Impreza wagon and he swears that's what caused the rust at the rear corner of his wheel wells. Almost every old Subaru I see has this rust in the same exact spot. Its good to hear that its normal.
I think the problem with our vehicles is that they are extremely boxy (but god is that ever nice!... just not aerodynamically speaking). See, after we cut the air apart with our vehicles, a big air vortex forms in the back of our vehicles. A steady stream is better than a mist, because the mist can possibly be just picked up by this air and move it away from the window.
Think of it this way, when you go through a car wash and drive down the street, your entire vehicle still remains clean when you stop (with certain exceptions, such as driving down a dusty trail...... ) but the rear of the vehicle always has some dust on it. I just experienced that today being my first wash with my recent pickup of my 04 XS.
Essentially, the two streams offer a thicker more concentrated stream that has some weight to get onto and down the window some.
