Well its not too difficult to make something that prevents this happening. A couple of years ago I designed a wash/wipe system for a tank and that had a delay before the wipers operated while washing.

I thought I'd mention this - just in passing ...

When I use the rear screen washer on my GV - I hit the button and the wiper starts, and a second or two later the fluid will start to spray - it will of course continue to spray for as long as I hold the button down.

I release the button, the fluid stops and the wiper will make another pass or maybe two across the screen (I've never really checked to see how many), and just as the wiper finishes - there will be a second very brief "squirt" of fluid - across the freshly wiped screen.

Not really - from my experience it doesn't seem to matter what the vehicle, or the weather is - they all work the same.

I'm visiting Tampa, Florida right now, driving a rented 2010 Ford Explorer - and whilst I was on the interstate last Friday, I hit the screen washer for the front screen, and this thread came to mind, as I watched the wipers cycle through a full cycle before the washer sprayed any fluid onto the screen.

That wasn't the first time I used the washer on that trip - it's pretty much a three hour drive - and I hate looking through squished bugs.

This is actually a long term peeve of mine because it can cause the wiper to cycle through one or more wipes on a dry screen, potentially scratching it - it's more of a problem with the rear screen, since that is usually the more dirty one - and - this is where I believe the problem originates - the washer fluid in the line has dried out and being a longer line to the rear, it takes longer to "pump through".



I would expect there to be a non-return valve there but maybe the problem is that it doesn't rain enough where you are!

You are right dear fordem,To avoid the scratches on windshield i need to delay the wiper motor start voltage ,also it need to stop before the glass gets dried. I will try to change R-C values and get back to you..thanks

No computer means no software - if the delay is handled by an RC circuit, you can increase it by increasing the value of either the resistor or the capacitor.

Now - I could be wrong on this, but I believe that circuit determines how long the wiper runs for after you stop washing - I don't think there is a delay between the washer & the wiper turn on times, at least not on the (older) Suzukis that I have.

This is actually a long term peeve of mine because it can cause the wiper to cycle through one or more wipes on a dry screen, potentially scratching it - it's more of a problem with the rear screen, since that is usually the more dirty one - and - this is where I believe the problem originates - the washer fluid in the line has dried out and being a longer line to the rear, it takes longer to "pump through".

It uses simple R-C network with 2 diodes and a NPN transistor,a zener diode and a relay.I dont think it is controlled by computer,,,Thanks

I'd need more details,are the wiper motor and and washer motor controlled by a computer or would it need a simple delay circuit in the wiper motor circuit?

I came across several wagon R cars with the problem of wiper motor starts few microseconds before the windshield motor activates whenever windshield cleaner switch operated.It seems a bug in software. Is it possible to delay the wiper motor turning  on time by 2 seconds or so?
