If it fails the test by showing voltage peaks and valleys, then you'd open it up and bend the wiper arm to follow another track. Or, buy a low mileage used one, which is what I'd do.

My "discovery" on one of my other cars, a Mercedes 190 2.6 was bad connections in the fuse box the washers and wipers did not function, rotation of the fuses solved that problem and
a a problem with sometimes difficult starting! Resistance was obviously the problem -worth a try.
