8R - 10 WIPERS/WASHERS
WASHER FLUID LEVEL SWITCH (Continued)
The washer fluid level switch is connected to the
vehicle electrical system through a dedicated take
out and connector of the right (except V-10 and diesel
engines) or left (V-10 and diesel engines only) head-
lamp and dash wire harness. The switch is connected
in series between a clean ground output of the Front
Control Module (FCM) on a sensor return circuit and
the washer fluid switch sense input to the FCM.
When the switch closes, the FMC senses the ground
on the washer fluid switch sense circuit. The FMC is
programmed to respond to this input by sending an
electronic washer fluid indicator lamp-on message to
the instrument cluster over the Programmable Com-
munications Interface (PCI) data bus. The instru-
ment cluster responds
illuminating the washer fluid indicator and by sound-
ing an audible chime tone warning.
The washer fluid level switch may be diagnosed
and tested using conventional diagnostic tools and
procedures. However, conventional diagnostic meth-
ods may not prove conclusive in the diagnosis of the
instrument cluster, the Front Control Module (FCM),
or the electronic message inputs to or outputs from
the instrument cluster and the FCM that control the
operation of the washer fluid visual and/or audible
indicators. The most reliable, efficient, and accurate
means to diagnose the washer fluid level indicator,
the instrument cluster, the FCM, or the electronic
message inputs and outputs related to the washer
fluid indicator requires the use of a DRBIII
tool. Refer to the appropriate diagnostic information.

REMOVAL

The washer fluid level switch can be removed from
the washer reservoir without removing the reservoir
from the vehicle.
(1) Unlatch and open the hood.
(2) Disconnect and isolate the battery negative
cable.
(3) Disconnect the washer hose from the barbed
outlet nipple of the washer pump/motor unit and
allow the washer fluid to drain into a clean container
for reuse.
(4) Disconnect the right (except V-10 and diesel
engine) or left (V-10 and diesel engine only) head-
lamp and dash wire harness connector for the washer
fluid level switch from the switch connector recepta-
cle (Fig. 7) or (Fig. 8).
NOTE: The pivoting float of the washer fluid level
switch must be in a horizontal position within the
reservoir in order to be removed. With the reservoir
empty and in an upright position, the pivoting float
will orient itself to the horizontal position when the
switch connector receptacle is pointed straight
upwards.
