system which includes:
• Pulse intermittent windshield wiper controller
• Wiper blades and arms
• Wiper motor
• Windshield washer reservoir

GENERAL INFORMATION
All models are equipped with electric operated
windshield washer pumps.
The wash function can be accessed in the OFF po-
sition of the wiper control switch. Holding the wash
button depressed when the switch is in the OFF po-
sition will operate the wipers and washer motor
pump continuously until the washer button is re-
leased. Releasing the button will stop the washer
pump but the wipers will complete the current wipe
cycle. Then followed by an average of two more wipe
cycles (
61) before the wipers park and the module
turns off.
Whenever a windshield washer malfunction occurs,
first verify that the windshield washer wire harness
is properly connected to all connectors before starting
normal diagnosis and repair procedures. Refer to
Windshield Washer Diagnosis Chart (Fig. 29).
The electric pump assembly is mounted directly to
the reservoir. A permanently lubricated sealed motor
is coupled to a rotor type pump. Fluid, gravity fed
from the reservoir, is forced by the pump through
rubber hoses to the nozzles which direct the streams
to the windshield.
The pump and reservoir are serviced as separate
assemblies on all vehicles.
