windshield wipers not working, but mechanism's motor works

What is your question?

The windshield wipers on my van stopped working, but the mechanism's motor still runs. I attempt to activate the wipers by adjusting the control switch and they remain still while I hear the motor working. How would I fix this, or better yet, where is the location of the wiper's mechanism in relation to the motor? Maybe the wipers became detached somehow?

How long has your 1992 Dodge B250 had this problem?
