I hate that when I use the washer on my windshield, my wipers screech across my dry dirty windshield before the washer fluid has made the windshield sufficiently wet.

 

Does anyone know how to make it so that there is a delay between when the sprayer sprays and the wipers begin wiping? Or, maybe more easily, just make it so that the sprayer just sprays, then I can run the wipers independently when I want to.

 

If no one has this documented, I'd be satisfied with just a wiring diagram. Then I'll figure it out myself and document it.

 

The car in question is a 2004 Forester, but I'd love to make the same modification to my other cars, as well.

jmoss5723,

 

I share your frustration on this issue, as many of the cars that I've owned over the years share the same problem.

 

I'm not certain that you'll find a work around without quite a bit of electronic timer circuitry knowledge, but have at it.

 

What I do is to turn the wipers on first, and then do the water blasting before and after the wipers run past the areas needing the cleanup. That way more fluid gets to the dirty sections. And if really dirty, again I turn the wipers on first, and then just hold the sprayer function on until I'm happy with the results.

 

I also have to add, that I purchase wiper fluid by the 4 pack case. Cheaper that way, and I have no excuse to keep the reservoir topped up because there is always some on hand.

Actually pretty easy to do, with a simple push button and a diode. But you need to know if the washer fluid pump is on a switched power or switched ground circuit. If you have a multimeter you can figure that out pretty easily.

I did it on my 2003 outback.

I think I love you.

It makes a huge difference. Every other car drives me nuts now...
