Six cylinder two wheel drive automatic 200,000 miles

I have 200,000 miles on it. For a while the windshield wipers would intermittently fail. Then a bit later they completely failed. I did a volt test at the motor and it was receiving twelve volts with the car not running just the key in the on position. It was receiving twelve volts at all the speeds.(high, low, delay). Since there was power to the motor and motor was not going i proceeded to replace the motor. Still same problem. What do you think?

First thought is a defective wiper motor right off the shelf. Second thought is the wiper transmission is binding.

Disconnect the wiper transmission from the motor and see if it then runs.
