Wiper Control Module: Description and Operation
SYSTEM OPERATION
Intermittent Wipe Module
An intermittent wipe module is used on vehicles that are not equipped with the optional Vehicle Theft Security System (VTSS). In addition to low
and high speed, the intermittent wipe system has a delay mode. Electronic circuitry within the intermittent wipe module is used to accomplish the
wiper delay mode. The delay time selected by the driver has a range of from about one-half second to about fourteen seconds.
The driver selects the length of the delay by placing the wiper (multi-function) switch knob in one of five different intermittent wipe detent
positions. One of the detent positions sends a battery voltage signal to the intermittent wipe module, while the other four positions use resistors to
provide progressively lower voltage signals to the module. If the washer knob is depressed while the wiper switch is in the Off position, the
intermittent wipe module will operate the wiper motor for approximately two wipes and automatically turn off the motor.
The intermittent wipe module is snap-fit onto a single blade-type mounting bracket located on the instrument panel reinforcement above the glove
box opening. The intermittent wipe module cannot be repaired and, if faulty or damaged, it must be replaced.
