DIAGNOSIS AND TESTING - WIPER SYSTEM
CONDITIONS
The following is a list of general wiper motor sys-
tem problems and tests that are to be performed to
locate the faulty part, and the corrective action to be
taken. When installing harness connector to motor
connector on vehicle, assure motor terminals are not
bent causing an open circuit to motor.
MOTOR WILL NOT RUN IN ANY SWITCH
POSITION
(1) Check fuse 5, in the Junction Block and fuse M
in the Power Distribution Center and. Refer to Wir-
ing Diagrams for pin call outs.
(a) If fuse(s) are good, go to Step 2.
(b) If fuse(s) are defective replace, and check
motor operation in all switch positions.
POSSIBLE CAUSE
1. LOOSE FLUID LEVEL
SENSOR CONNECTOR.
2. OPEN POWER CIRCUIT
TO SWITCH.
3. OPEN GROUND
CIRCUIT.
4. DEFECTIVE
INSTRUMENT CLUSTER
5. FLUID LEVEL SENSOR
SWITCH OPEN OR
DEFECTIVE.
1. FILLER TUBE LEAKING.
2. FILLER TUBE OUT OR
DAMAGED.
3. PUMP OR SENSOR
GROMMET DEFECTIVE.
4. LEAKING OR DEFECTIVE
RESERVOIR BODY.
CORRECTION
1. PROPERLY SEAT CONNECTOR TO SWITCH.
2. OPEN OR DEFECTIVE CIRCUIT BETWEEN
INSTRUMENT CLUSTER CONNECTOR
TERMINAL #B4 AND LOW FLUID LEVEL
SENSOR CONNECTOR TERMINAL. IF NOT OK,
REPAIR CIRCUIT.
3. OPEN OR DEFECTIVE CIRCUIT BETWEEN
FLUID LEVEL SENSOR CONNECTOR AND
LEFT HEADLAMP GROUND #5 OR ENGINE
GROUND #1 OR 2.
4. REFER TO INSTRUMENT CLUSTER
DIAGNOSTIC PROCEDURES.
5. CONNECT AND OHMMETER TO SWITCH
TERMINALS TO CHECK FOR COMPLETE
CIRCUIT. CYCLE SWITCH FLOAT BACK AND
FORTH BY FILLING AND DEPLETING
RESERVOIR OF WASHER FLUID TO CHECK
FOR PROPER SWITCH FUNCTION. IF NOT OK,
REPLACE SWITCH.
1. ASSURE FILLER TUBE IS NOT LOOSE OR
DISCONNECTED. IF NOT OK, PROPERLY
SEAT FILLER TUBE.
2. REPLACE FILLER TUBE.
3. REPLACE PUMP OR SENSOR GROMMET.
4. REPLACE RESERVOIR BODY.
(c) If motor is still inoperative and the fuse does
not blow, go to Step 2.
(d) If replacement fuse blows, go to Step 11.
(2) Disconnect motor wire harness connector.
(3) Check the wiper motor low speed. Using two
jumper wires, connect one jumper wire between the
battery positive jump start terminal and Pin 2 on the
wiper motor connector. Connect the other jumper
wire to ground and Pin 5 on the wiper motor connec-
tor. Check the wiper motor high speed, connect the
positive jumper wire to Pin 1 on the wiper motor con-
nector. Connect the negative jumper wire to Pin 5 on
the wiper motor connector.
(a) If motor runs, go to Step 4.
(b) If motor does not run, high or low speed
replace the wiper motor.
(4) Using an ohmmeter, check for good ground at
Pin 5 of the wiper motor wire harness connector. If
not OK, repair the ground circuit as necessary. If OK,
go to Step 5.
