I've replaced my wiper moter new. It works fine on high but low and intermidiate only works acationaly. I picked up a used turn and wiper switch from junk yard. its still doing same thing. doese anyone have any ideas for me?

 

I 've fixed my own problem ford has a delay module located under the dash in the middle. you can get a new one at ford deler for 120. I got one out of the junk yard for $10
