INSTALLATION
1. Position the rear wiper motor (5) and bracket into
the tailgate (2) as a unit.
2. Insert the rear wiper motor output shaft through the
hole in the tailgate outer panel and engage the two
mounting screws (3) into the keyed slots (1) in the
top of tailgate inner panel.
3. From the outside of the tailgate (3), center the rear
wiper motor output shaft (2) in the tailgate outer
panel clearance hole and install the gasket and
bezel (1) over the centered shaft.
4. Install and tighten the nut (4) that secures the rear
wiper motor output shaft to the outer tailgate panel.
Tighten the nut to 5 N·m (43 in. lbs.).
5. From the inside of the tailgate, tighten the two
screws that secure the rear wiper motor mounting
bracket to the top of the tailgate inner panel.
Tighten the screws to 6 N·m (57 in. lbs.).

the rear wiper motor to the motor connector recep-
tacle.
7. Reconnect the tailgate wire harness connector for
the flip-up glass ajar switch to the flip-up glass
latch connector receptacle.
8. Reinstall the trim panel onto the tailgate inner panel. (Refer to 23 - BODY/SWING GATE/TRIM PANEL - INSTAL-
LATION).
9. From the outside of the tailgate, press the nut cover (5) firmly and evenly over the rear wiper motor output shaft
bezel using hand pressure until it snaps into place.
10. Reinstall the rear wiper arm onto the rear wiper motor output shaft. (Refer to 8 - ELECTRICAL/REAR WIPERS/
WASHERS/REAR WIPER ARM - INSTALLATION).
11. Reconnect the battery negative cable.

WASHER FLUID LEVEL SWITCH
DESCRIPTION
The washer fluid level switch is a single pole, single
throw reed-type switch mounted just above the sump
area near the bottom of the washer reservoir. Only the
molded plastic switch mounting flange (1) and the
integral connector receptacle (5) are visible when the
switch is installed in the reservoir. A short nipple for-
mation (4) extends from the inner surface of the
switch mounting flange, and a barb on the nipple near
the switch mounting flange is pressed through a rub-
ber grommet seal installed in the mounting hole of the
reservoir.
A molded plastic float (3) rides saddle-like over a molded plastic beam that extends axially from the switch mounting
flange. A small permanent magnet (2) is secured in a receptacle on the top of the float, and the reed switch is
concealed within the beam. A diagnostic resistor is connected between the two switch terminals within the switch
mounting flange. The washer fluid level switch cannot be adjusted or repaired. If inoperative or damaged, the switch
must be replaced.
OPERATION
The washer fluid level switch uses a float to monitor the level of the washer fluid in the washer reservoir. The float
contains a small magnet. When the float moves, the proximity of this magnet to a stationary reed switch within the
beam formation of the switch changes. When the fluid level in the washer reservoir is at or above the float level, the
float rises and the influence of the float magnetic field is removed from the reed switch causing the normally open
reed switch contacts to open. When the fluid level in the washer reservoir falls below the level of the float, the float
falls and the influence of the float magnetic field is applied to the reed switch, causing the contacts of the normally
open reed switch to close.
The washer fluid level switch is connected to the vehicle electrical system through a dedicated take out and con-
nector of the headlamp and dash wire harness. The switch is connected in series between ground and the washer
fluid switch sense input to the ElectroMechanical Instrument Cluster (EMIC). The switch receives a path to ground
at all times through another take out of the headlamp and dash wire harness with a single eyelet terminal connector
that is secured under a ground screw near the front of the left front fender inner shield in the engine compartment.
When the switch closes, the EMIC senses the ground on the washer fluid switch sense circuit. The EMIC is pro-
grammed to respond to this input by illuminating the washer fluid indicator and by sounding an audible chime tone
warning.
The washer fluid level switch input to the EMIC may be diagnosed using conventional diagnostic tools and methods.
(Refer to 8 - ELECTRICAL/INSTRUMENT CLUSTER/WASHER FLUID INDICATOR - DIAGNOSIS AND TESTING).
REMOVAL
NOTE: The washer fluid level switch can be removed from the washer reservoir without removing the res-
ervoir from the vehicle.

WHEELHOUSE SPLASH SHIELD - REMOVAL).
6. Pull the forward end of the front wheelhouse splash
shield away from the inner fender panel and front
fascia far enough to access the washer fluid level
switch (4) for service.
7. Disconnect the headlamp and dash wire harness
(2) connector (1) for the washer fluid level switch
from the switch connector receptacle.
8. Using a trim stick or another suitable wide flat-bladed tool, gently pry the barbed nipple of the washer fluid level
switch out of the rubber grommet seal on the reservoir just above the sump. Care must be taken not to damage
the reservoir.
9. Remove the washer fluid level switch from the washer reservoir.
10. Remove the rubber grommet seal from the washer fluid level switch mounting hole in the washer reservoir and
discard.
INSTALLATION
1. Install a new rubber grommet seal into the washer
fluid level switch mounting hole in the washer res-
ervoir. Always use a new rubber grommet seal on
the reservoir.
2. Insert the float of the washer fluid level switch (4)
through the rubber grommet seal and into the
washer reservoir. The connector receptacle of the
washer fluid level switch should be pointed down-
ward.
3. Using hand pressure, press firmly and evenly on
the washer fluid level switch mounting flange until
the barbed nipple is fully seated in the rubber
grommet seal in the washer reservoir mounting
hole.
4. Reconnect the headlamp and dash wire harness
(2) connector (1) for the washer fluid level switch to
the switch connector receptacle.
5. Reposition the forward end of the front wheelhouse
splash shield to the inner fender panel and the
front fascia.
6. Reinstall the plastic push-in fasteners that secure the front wheelhouse splash shield to the inner fender panel
and the front fascia. (Refer to 23 - BODY/EXTERIOR/FRONT WHEELHOUSE SPLASH SHIELD - INSTALLA-
TION).
