Hi all,

a question for those who have fitted electric windscreen washers to your cars. Assuming you have a pushbutton to operate the washers, does anyone know of a kit or method to operate the wipers for about 4 wipes a second or so after the washer button is pushed, similar to modern cars?

Thanks, Paul

I found this website, I believe it is USA based. Not sure if this will work but some experimentation would be worthwhile.

Thanks Grant for those circuits

Cheers, Paul
