The wiper motor hopefully is ok, but if the wiper arms were not mounted at the right spot, it could have damaged the motor as it returned to the rest position, unfortunately.

If there is noise, the noise could be coming from the wiper arm joint being stripped out or the motor itself assuming that the ball joints under the hood and behind the firewall are still connected.

Check these items, and I'm sure you will get to the bottom of this.

Good luck on this repair.

Try to run the motor without the wiper arms tightened down and turn it off so it can cycle down to its rest state. Then install the wiper arms.

Make sure, that the car's windshield wiper wiring is correct for this motor.
