Problem With the wipers on a 2002 Ford Econoline Diseal

1.The problem that i am having with it is that the wipers only have two speeds. A sami slow one and a semi fast one. And mothing in
between. The first position will tun the wipers on and the Last will make them work a little faster.
2.When i click the botton to wash my windshield the wipers turn one and never stop. I have to turn off the van to turn them off. :?
If any one could Help me out on how to solve these problems i will really apreciate that.
Thanks Roman :lol:
