GENERAL DESCRIPTION
Figs. hand 2
The Permanent Magnet (PM) Depressed Park
windshield
(w/s) wiper with remote washer pump sys-
tem consists of a depressed park wiper motor and a
remote washer pump mounted on the washer fluid
container.
Based on the type of control switch used and
whether an optional electronic printed circuit board is
attached in the wiper cover, the system can serve as
either a pulse type wiper-washer system or a standard
type windshield wiper. Pulse timing and "demand"
wash functions are controlled electronically on pulse
windshield wipers.
WIPER AND WSHER OPERAflON
Pulse Windshield Wiper System Fig. 1 Wiper Motor
Electronic logic circuits on a pulse wiper system's
printed circuit board establish all timing and washer
commands. When the WASH switch is pressed, the
washer sprays only during the wiper arm
outwipe and
pulsates operation for 2-1/2 seconds. Then the wiper
dry wipes for nearly
6 seconds before shutting off. See
Pulse Wiper Operation Chart, Fig.
3, for a brief de-
scription of pulse wiper system operation.
If the WASH switch is pressed for more than one
second, a (demand) wash is performed for as long as
the switch is depressed. This wash action is followed by
6 seconds of dry wipes before shut-off. With the control
switch in the
LO or HI speed position, the respective
