The windshield wipers want move back down when i

On the wiper motor there is a function called the "park" mode. If the wipers are not returning to the bottom of the windshield the park mode of the wiper motor is malfunctioning. The most common fix for this problem is to replace the wiper motor.
If you have the ability to disassemble the wiper motor you should see a set of contacts inside the wiper motor transmission. These contacts get worn over a period of years and sometimes just a good cleaning will solve the problem.
