Windshield Wipers/Washer
NOTE: The ignition key must be turned to ACC or
IGN & ACC for the wiper/washer switch to operate.
A five-position windshield wiper switch controls the
wipers and washer. To turn ON the wipers, turn the knob
clockwise.
• For intermittent operation turn to the 1st and 2nd posi-
tions; for continuous operation advance to the 3rd and
4th positions.
• The final option activates the washer cycle. To wash the
windshield, push knob IN and release. Hold knob IN to
extend washing cycle. After one to three wipes (depend-
ing on how long you hold the switch in) the wipers will
shut off automatically.
The windshield washer tank is located inside the engine
compartment below the radiator expansion tank. See
“Washer Reservoir” on page 201
. Check the windshield
washing fluid level weekly. If necessary, fill to top.
CAUTION: If the electric pump is operated for a
long period (more than 15 seconds) with a dry
reservoir, the pump rotor may be damaged.
