Motor for Wiper Blades got loud!?

i'd definately utilize it!

Get it fixed and then start using a product which works like Rain-X which is mixed in with a cleaner ( I use Duragloss Rain Repel #751) once a month (easy to use don't have to wait for it to dry, just wipe it on and wipe off while it cleans your windshield. This will make it a bit easier for your wipers to wipe (and a lot less stress on the motor(s))...also a higher speeds you'll find you won't even need your wipers.
