3 spd. wiper motor

I canand have gotten a 'one sweep' intermitent wiper feature from the earlier 2 speed and 3 speed wiper systems , using the "push for wash" portion of their switches.
The later types that reverse to park and rotate the switch to low speed upon "push" are totally different circuitry.
I whipped that rotation in one those switches but have yet to go back after the one sweep conection in that type or determined if it's doable. Maybe someday I will.
Other things that changed about wipers are the linkage, bushings, and pitman arms.
