CONDITION
POSSIBLE CAUSES
CORRECTION
WIPER MOTOR OPERATES
SLOWLY IN ALL SWITCH
POSITIONS
1. Ineffective wiper motor.
1. Check amperage draw with linkage
disconnected from wiper motor crank arm.
Correct draw should be about 6 amperes. If
incorrect, refer to the appropriate Possible
Cause that follows:
2. Amperage draw too low.
2. Test and repair shorted low or high speed
feed circuit if required.
3. Amperage draw too high.
3. With linkage disconnected from wiper
motor crank arm check linkage and pivots
for binding. If binding is detected, repair or
replace front wiper module if required. If no
linkage binding detected, replace the front
wiper motor if required.
WIPERS RUN AT HIGH SPEED
WITH SWITCH LOW SPEED
SELECTED OR AT LOW
SPEED WITH SWITCH HIGH
SPEED SELECTED
1. Ineffective motor feed circuit
wiring.
1. Test and repair low speed and high
speed feed circuit wiring between TIPM and
front wiper motor if required.
2. Ineffective switch wiring.
2. Test and repair jumper harness wiring
between right multi-function switch and
SCM (left multi-function switch) if required.
3. Ineffective right multi-function
switch.
3. Test and replace right multi-function
switch if required. (Refer to 8 -

AND TESTING).
REAR
WARNING: To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental
restraint system before attempting any steering wheel, steering column, airbag, occupant classification sys-
tem, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge
before performing further diagnosis or service. This is the only sure way to disable the supplemental
restraint system. Failure to take the proper precautions could result in accidental airbag deployment, pos-
sible personal injury or death.
If the rear wiper motor operates, but the wiper motor output shaft does not move, replace the ineffective rear wiper
motor. If the washer pump/motor operates, but no washer fluid is dispensed on the glass; or, if the wiper operates,
but chatters, lifts, or does not clear the glass, clean and inspect the rear wiper and washer system components as
required. (Refer to 8 - ELECTRICAL/WIPERS/WASHERS - CLEANING - REAR) and (Refer to 8 - ELECTRICAL/
WIPERS/WASHERS - INSPECTION - REAR).
The hard wired rear wiper and washer system circuits and components may be diagnosed using conventional diag-
nostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring dia-
grams, 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.
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the rear wiper and washer
system or the electronic controls or communication between other modules and devices that provide some features
of the rear wiper and washer system. The most reliable, efficient, and accurate means to diagnose the rear wiper
and washer system or the electronic controls and communication related to rear wiper and washer system operation
requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
