Can anyone help me out with info on the intermittent wipers? I'm sure there is some kind of box that controls the power to the multi-function switch to operate the intermittent function for the wipers. In my Jeep there is a small black box that plugs in-line with the multi-function switch wiring harness.

 

Wiper control module. Under the LH side of the instrument panel, near the steering column support.
