Brian, do you have this year and model car?

Tom, then by all means...go for it!  I agree that on some vehicles it may
be easy to access but you cannot generalize with the way cars are being
built today.

Take it apart, if you can, and worst case you take it to the dealer to
finish what you were unable to complete.

Why not? The linkage is VERY simple and it's accessible through the
grill at the base of the windshield. Wiper repairs are generally an easy
DIY job.

Tom, if the drivers side works correctly and the passengers side moves
freely, it sounds like the linkage is broken tying both wipers to the
motor assembly.  As far as a fix, I would take it to the dealership as I
do not believe this is something you want to attempt to repair on your
own.

I have an '02 Elantra that my son takes to college.  Just before he left
today (college is 262 miles away) he reported his passenger-side wiper is
not working (driver's works fine).

Indeed, I was able to move it freely back and forth - something I should not
be able to do (and something the driver's does not do).

He was in a hurry to leave, but will be back home in a few days (Fall
break).  The assembly does not look that easy to access, and have no idea
what I will find.

Ideas??
