Hi all. I'm thinking of making intermittent wiper controller the way attached schematic points but I'm thinking of modifying it a little bit. My car does have intermittent wiper but it has same interval all the time. I would like to use the same switch but instead using a new relay i think of using the one that car all ready have. This (I think) could be achieved by replacing relay (in schematic) with some sort of transistor which would just pass the impulse to the original car relay just as if I pulled the handle once (for wipers to wipe only once). As you can guees I don't know how to implement my idea so please help. Cheers
