Windshield Wipers Only Work on Highest Setting?

[B_Schlomy]

I have an 03 MM. When I bought it the windshield wipers only worked on high and the washer fluid wouldn't dispense, so I did some research on it and replaced the multifunction switch but that didn't work. Dopes anyone have any suggestions on what to do or what the problem could be.

Sounds like the wiper motor needs to be replaced and the tubing that the washer fluid traverses could be blocked/plugged/leaking. Where the wiper motor is located is where debris and water likes to hang out and if not cleaned out every once in a while will cause issues. When you try to activate washer fluid, check in the engine bay or underneath car for any runoff.
