I'm guessing wiper motor.... My truck was doing that same thing and that was the problem. Or also try the multi function switch

Re: winshield wipper problem
i had a 1988 broncoII and i had to get out and hit the wiper motor just to get it to work. and it only worked on high, if i put it on delay it would stop working.
i replaced the motor and it still did it but i didnt have to hit the motor. so i replaced the wiper switch and never had the problem agian. so i agree with rtgta. replace the switch and if that dont stop it. do the motor. Joined: Aug 1999

Re: winshield wipper problem
The delay circuits inside the wiper motor cover are probably burnt out.
It sounds like when the wipers are working at full speed and you turn the lever back ( into the DELAY zone on the lever ) the wipers stop working until the lever is turned all the way to LOW or OFF. If that's true that the delay switch in the lever is working,...... The motor realizes that the lever has moved from HIGH to DELAY - but the delay circuits are blown out so the wipers do not respond. Once the lever reaches the LOW or OFF setting; they work again. (This is exactly what happens when a non-delay wiper motor is installed on a car that had delay wipers from the factory. )
Replace the Motor before replacing the lever - or at least probe the wiper wires with a voltmeter at the bottom of the cloumn before buying parts to be sure.

Re: winshield wipper problem
if you only have one speed it what is it? if it is HI then you are bypassing everything and going right to the motor via the purple lead.
if it is low then you still have part of the circuit and are using only the grey lead.
in any event you problem is not the motor, if it works at all then its fine.
your problem is via the green or pink leads that control variable hi/lo or pulse delay, respectively.
so pull the green and pink leads - mark them - see if there is any difference.
if not then pull the purple lead and see if it still works and if it does then switch the purple and grey to see if you have any speed change.
at least you will know that the switch still works in HI/LO mode.
in any event - its not a motor problem. if the motor works at all then it works.
Good luck
