or until the ignition switch is turned to the Off posi-
tion, whichever occurs first. When the switch toggle
button is depressed downward to its Wipe detent
position, the switch provides ignition switched bat-
tery current to the rear wiper motor and the rear
wiper system operates. When the switch toggle but-
ton is depressed downward to the momentary Wash
position, the switch provides ignition switched bat-
tery current to both the rear wiper motor and the
rear washer pump motor for as long as the switch is
held depressed. Refer to the owner’s manual in the
vehicle glove box for more information on the fea-
tures, use and operation of the rear wiper and
washer switch.
The incandescent switch illumination lamp is con-
trolled by a lamp driver output from the instrument
cluster based upon the panel lamps dimmer input to
the cluster from the left multi-function switch. The
rear wiper and washer switch can be diagnosed using
conventional diagnostic tools and methods.
DIAGNOSIS AND TESTING - REAR WIPER &
WASHER SWITCH
Be certain to perform the diagnosis for the rear
wiper system and/or rear washer system before test-
ing the rear wiper and washer switch. (Refer to 8 -
ELECTRICAL/REAR WIPERS/WASHERS - DIAG-
NOSIS AND TESTING). Refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, details of wire harness routing and
retention, connector pin-out information and location
views for the various wire harness connectors, splices
and grounds.

(1) Disconnect and isolate the battery negative
cable. Remove the accessory switch bezel from the
instrument panel and disconnect the instrument
panel wire harness connector for the rear wiper and
washer switch from the switch connector receptacle.
(2) Using an ohmmeter, check the rear wiper and
washer switch continuity at the switch terminals as
shown in the Rear Wiper & Washer Switch Continu-
ity chart (Fig. 24).
