2002 DODGE RAM power steering fluid

contains all of the switches for both the wiper and
washer systems.
²Washer Fluid Level Switch- The washer fluid
level switch is located in a dedicated hole on the
lower rear side of the washer reservoir, above the
washer pump/motor unit near the left front corner of
the engine compartment.
²Washer Nozzles- The dual fluidic washer noz-
zles are secured with integral snap features to dedi-
cated openings in the cowl plenum cover/grille panel
located near the base of the windshield. The washer
plumbing fittings for the washer nozzles are con-
cealed beneath the cowl plenum cover/grille panel.
²Washer Pump/Motor- The washer pump/mo-
tor unit is located in a dedicated hole on the lower
rear side of the washer reservoir near the left front
corner of the engine compartment.
²Washer Reservoir- The washer reservoir is
secured to the left side of the radiator fan shroud in
the left front corner of the engine compartment.
²Wiper Arms- The two wiper arms are secured
to the two wiper pivots, which extend through the
cowl plenum cover/grille panel located near the base
of the windshield.
²Wiper Blades- The two wiper blades are
secured to the two wiper arms, and are parked on
the glass near the bottom of the windshield when the
wiper system is not in operation.
²Wiper Module- The wiper pivots are the only
visible components of the wiper module. The remain-
der of the module is concealed within the cowl ple-
num beneath the cowl plenum cover/grille panel. The
wiper module includes the module bracket, the single
wiper motor, the wiper linkage, and the two wiper
pivots.
²Wiper Relay- The wiper relay is located in the
Power Distribution Center (PDC) in the engine com-
partment near the battery.
Features of the wiper and washer system include
the following:
²Continuous Wipe Modes- The two-speed
wiper motor and the internal circuitry of the multi-
function switch work in concert to provide two con-
tinuous wipe cycles, low speed or high speed.
²Intermittent Wipe Mode- The internal cir-
cuitry of the multi-function switch, the CTM, and the
wiper relay work in concert to provide an intermit-
tent wipe mode with multiple delay interval selec-
tions. On models with a high-line or premium CTM,
the CTM also automatically adjusts each manually
selected delay interval to compensate for vehicle
speed.
²Washer Mode- When the washer system is
activated with the multi-function switch while the
wiper system is operating, washer fluid will be dis-
pensed onto the windshield glass through the washernozzles for as long as the washer pump/motor is
energized.
²Wipe-After-Wash Mode- The internal circuitry
of the CTM provides a wipe-after-wash feature
which, if the wipers are turned Off, will operate the
washer pump/motor and the wipers for as long as the
washer system is activated, then provide several
additional wipe cycles after the washer system is
deactivated before parking the wiper blades near the
base of the windshield.
Hard wired circuitry connects the wiper and
washer system components to the electrical system of
the vehicle. These hard wired circuits are integral to
several wire harnesses, which are routed throughout
the vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the wiper and washer
system components through the use of a combination
of soldered splices, splice block connectors, and many
different types of wire harness terminal connectors
and insulators. Refer to the appropriate wiring infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-
tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
OPERATION
The wiper and washer system is intended to pro-
vide the vehicle operator with a convenient, safe, and
reliable means of maintaining visibility through the
windshield glass. The various components of this sys-
tem are designed to convert electrical energy pro-
duced by the vehicle electrical system into the
mechanical action of the wiper blades to wipe the
outside surface of the glass, as well as into the
hydraulic action of the washer system to apply
washer fluid stored in an on-board reservoir to the
area of the glass to be wiped. When combined, these
components provide the means to effectively main-
tain clear visibility for the vehicle operator by remov-
ing excess accumulations of rain, snow, bugs, mud, or
other minor debris from the outside windshield glass
surface that might be encountered while driving the
vehicle under numerous types of inclement operating
conditions. The vehicle operator initiates all wiper
and washer system functions with the multi-function
switch control stalk that extends from the left side of
the steering column, just below the steering wheel.
Rotating the knob on the end of the multi-function
switch control stalk selects the desired wiper system
operating mode. The wiper system allows the vehicle
operator to select from two continuous wiper speeds,
Hi or Lo, or one of several intermittent wipe Delay
mode intervals. Pushing the button on the end of the
control stalk downwards towards the steering column

STEERING
DESCRIPTION
The power steering system consist of a steering col-
umn, steering gear and hydraulic pump. The gear is
mounted to the frame rail and attaches to the steer-
ing linkage. The pump is a constant flow rate and
displacement vane-type pump. The pump supplies
hydraulic fluid pressure to the power steering gear
(Fig. 1).
Vehicles equipped with trailer tow option have a
power steering pump oil cooler.
OPERATION
The gear acts as a rolling thread between the
worm shaft and rack piston. The worm shaft is sup-
ported by a thrust bearing at the lower end and a
bearing assembly at the upper end. When the worm
shaft is turned from input from the steering column
the rack piston moves. The rack piston teeth mesh
with the pitman shaft. Turning the worm shaft, turns
the pitman shaft, which turns the steering linkage.

DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - POWER STEERING SYSTEM
STEERING NOISE
There is some noise in all power steering systems. One of the most common is a hissing sound evident at a
standstill parking. Or when the steering wheel is at the end of it's travel. Hiss is a high frequency noise similar
to that of a water tap being closed slowly. The noise is present in all valves that have a high velocity fluid passing
through an orifice. There is no relationship between this noise and steering performance.

DIAGNOSIS AND TESTING - POWER STEERING
FLOW AND PRESSURE
The following procedure is used to test the opera-
tion of the power steering system on the vehicle. This
test will provide the flow rate of the power steering
pump along with the maximum relief pressure. Per-
form test any time a power steering system problem
is present. This test will determine if the power
steering pump or power steering gear is not function-
ing properly. The following pressure and flow test is
performed using Power Steering Analyzer Tool kit
6815 (Fig. 2) and Adapter Kit 6893.
POWER STEERING ANALYZER INSTALLATION
WITHOUT HYDRAULIC BOOSTER
(1) Remove the high pressure hose from the power
steering pump.
(2) Connect Tube 6844 into the pump hose fitting.
(3) Connect pressure gauge hose from the Power
Steering Analyzer to Tube 6844.
(4) Connect Adapter 6826 to Power Steering Ana-
lyzer test valve end.
(5) Connect the power steering hose from the
steering gear to Adapter 6826.
WITH HYDRAULIC BOOSTER
(1) Remove high pressure hose which goes to the
steering gear from the tube coming out of the booster.
(2) Connect Adapter 6826 to the Power Steering
Analyzer pressure gauge hose.
(3) Connect pressure gauge hose to the tube com-
ing out of the booster.
(4) Connect Tube 6844 to the steering gear hose
and Power Steering Analyzer test valve end.
FLOW AND PRESSURE TEST
(1) Check belt condition and tension.
(2) Open the test valve completely.
(3) Start engine and let idle long enough to circu-
late power steering fluid through flow/pressure test
gauge and to get air out of the fluid. Then shut off
engine.
(4) Check fluid level, add fluid as necessary. Start
engine again and let idle.
(5) Gauge should read below 1034 kPa (150 psi), if
above, inspect the hoses for restrictions and repair as
