While I have not had this issue nor done the full procedure I have had the cowel and wiper arms off. Its relatively straightforward and not time consuming. About the wiper motor, I have no experience.

If you go this route, know that the window washer hoses are part of the wiper arms and on a car our age are somewhat fragile. Also the arm mounting bolt black hats have a tendency to walk away and also can be a pain to find replacements for.

If you go this route let us go along with you please.
 
As a thought, if you have a gopro camera you can put it in different locations and record audio and video. it can be a useful diagnostic tool.
