If the windshield wipers work when pushing the lever down but not when they are turned on all the time, the problem could be in the wiper motor relay switch. There are two different relay switches for the windshield wipers, so that if the one fails a person can still clear the windshield manually.
What type of vehicle?
check the fuse, otherwise the linkeage or the motor broke down
Turn the wipers off, pull the wiper arm off, and replace it in the correct down position.
You must remove the arm of the wiper and move it down
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.
Remove the bottom bolt on each side of the windshield (near the hinge) and make sure to take the wipers off. It folds right down, really easy, Remove the bottom bolt on each side of the windshield (near the hinge) and make sure to take the wipers off. It folds right down, really easy,
I would start with testing the "park" switch inside the cover of the windshield wiper motor.
They do because if they go up and down, the water would just stay on the window.
I have found that if you put rainex on the windshield everytime you change your oil you will not have that problem.
Assuming you are standing on the drivers side, lightly pull the windshield wiper towards you until you hear a click and then lightly pushit back down.
Sometimes there is a racket system and the wipers have slipped. Used to happen all the time in my 1998 Buick. Always had to take them apart and put them back together.
