Wiper motors

[Roland L-Ocala FL]

A little help please,
I may be beating a dead horse, but which wiper motor controls the other on a 1994 RT/10. My passenger side one is out of sync with the driver side one, and the blades tangle up, so for now, I have removed the passenger side blade and arm. However, I have a chance to pick up either motor at a reasonable price, and would like some info as to which one is the controlling side, or is there one? Any constructive comments would be appreciated.
Thanks!

If the passenger side wiper is out of synch, replace the driver side motor or vice versa

Easily searchable topic, but what Chad says is basically correct.

The crazy motor is the good one.

There is a controller, but it rarely goes bad.....it is what's making the good motor go crazy, trying to synchronize w/ the bad motor
