Was told about this today, not sure if it's commonly known or not, did a search but couldn't find anythin. So anyway.... It is possible to change the speed of the intermintant wiper, all u do is, 1) turn intermitant on 2) turn off again 3) leave off for dessired amount of seconds (think 15 is max) 4) put intermitant bk on now the wipers will wipe with that particular time period
