This sounds like the park circuit is shorted.

These are a tight fit...Spray a little penetrating lubricant onto it and let it sit for about 20 minutes. You will notice there are splines that match up from the drive unit to the base of the wiper arm...sometimes these can get a little corroded and becasue of the relative surface area it makes them a real pain to get off. You may need to just pry against it gently with a flat head scredriver after you spray on the lubricant. Pray at it from all different sides of the base so that it doesn't bind up and get crooked.
Hope this helps! Good Luck!

look closely/carefully for recessed screws. Most are usually pop on/ pop off types. Pull/ pry gently.

May want to look at replacing the wiper circuit board.It is located on the firewall adjacent to the wiper motor and has a some what square black cover with 3 torx screws and wireing harness pluged into the side.We had a truck that every time you washed it the wipers would stay on until it dryed out.You can try removing it and spaying it down with contact cleaner just watch the brease on the two contact tips.Well hope this helps.

It
can be faulty wiper motor or blown wiper control fuse.
Do
you hear any kind of noise when you starter the wiper function. If yes then
fuse is ok, but issue is wiper motor.
If
no movement at all and no noise then its blown fuse or shorted/loose wiper
