What is the labor time to replace a front wiper motor?

I couldn't open the video. But if this is the instructional video of the mechanic replacing it, then I already viewed it. The video I viewed was a different year though, so it may not be the same. I took the car to the dealer because I was booked for the weekend and couldn't repair it myself. Someone mentioned .9 hours of labor.

The wipers are touching/ sweeping the windshield, but are not in the right position. Would that have to do with the motor itself being bad after Running disconnected, or that the mechanic didn't adjust the linkage correctly to the motor when he reassembled it together.

Could just be the wiper arms were not attached at the correct position and the motor is operating fine.
