Wipers not going back down

My wipers stop and the end of the “up” travel. If I push them back “down” it will cycle and get stuck in the up position again.

I believe that it is the gears in the wiper motor and that the wiper motor needs to be replaced. All I would like to know is if my diagnosis is correct or if further investigation is needed. I am also seeing posts about wiper adjustment. I will read those when I get the new parts, but I believe that putting that procedure here will be good for those who come after me.

Take the wiper arms off and reposition them on the post.

Or -

Won't go down when you want? Time for an upgrade - Trade her in for a newer model!

Try @Edelbrock's advice first. Could be as simple as when the arms were reinstalled, they weren't positioned correctly. Otherwise, it'll be the park position in the motor that's possibly wiped out. Easy enough job to swap out the wiper motor if the first option or repositioning the wiper arms doesn't work.

the wiper linkage is attached to the motor out 180 degrees. disconnect the linkage, move the wipers down, turn the switch on and off so the motor parks, reattach linkage to motor with wiper in park position and motor in park position.

only 1 time does a person install a new wiper motor without cycling the switch to make sure it is in the park position. I know from experience.
