I would start with testing the "park" switch inside the cover of the windshield wiper motor.
On Jeep YJs the wipers dont go all the way down.
What type of vehicle?
possible faulty relay
remove wiper arms from vehicleturn wipers onthen turn wipers offshut off ignitionreplace wiper arms at the down positionthis should be the return position when ever u shut wipers off
The linkage for the wipers could have slipped. If the linkage is not aligned right, then the wipers will not stop at the right spot.
The wiper motor has a sensor plate under the wiper links above the motor they go up instead of down if this is not making the contact it needs to tell if the wipers are in position replace this and your problems will be solved
The wiper motor has a switch inside of it. When they are turned off and the wipers go to the down position it trips the switch in the motor that tells the computer they are in the down position. If that switch in the motor is faulty, the wipers are repositioning until the switch is tripped to the off position. THE FIX.... Replace the wiper motor.
They do because if they go up and down, the water would just stay on the window.
The windshield wipers are not automatic... the lever that controls the wipers have three positions and you will have to pull the lever down to the off position. The position below off is for mist. If you pull the lever to that position and let it go, the lever will go back to the off position.
The windshield wipers go back in forth if you now now what i mean
I had the same thing on my 2000 Crown Vic PI and it was the motor.
there was a factory recall on one of the wiper motors.
