The windshield washer (Fig. 1) consists of a
reservoir mounted motor driven displacement type pump
that delivers washer solution to the windshield through
hoses and nozzles in the wiper arms. Pump motor may
be integral with reservoir or detached.
Two types of controls are used with the
windshield washer namely - an integral with wiper control
switch type for electric wipers and an independent
control type for air wipers. (Independent switch is
mounted on instrument panel directly below wiper control
valve.) You can operate windshield washer with either
type control simply by pushing in on control switch for as
long as you want nozzles to spray. Spray will stop as
soon as control is released.
A minimum of service is required to keep
windshield washer operating. Keep reservoir filled with
IH No. 996726-R2 windshield washer solvent and keep
wiper nozzles clean. If dirt enters reservoir, remove
reservoir and flush out with clean water. Refill reservoir
with specified solvent after reinstalling.
