The wiper control module on a 1993 Ford F-150 isn't a separate, easily identifiable module like in some later vehicles. The wiper motor control functionality is integrated into the
multi-function switch (also called the turn signal/wiper switch) located on the steering column.
Therefore, there isn't a specific "wiper control module" to locate. If you're having wiper problems, the likely culprit is either the multi-function switch itself, a wiring issue related to it, or the wiper motor.
