1. Remove the wiper/washer switch (see page 22-234).
2. Disconnect the dashboard wire harness 8P
connector (A) from the wiper/washer switch (B).
3. Check for continuity between the terminals in each switch position according to the table.
4. If the continuity is not as specified, replace the switch. 1. Remove the wiper arms (see page 22-233).
NOTE: Carefully remove the wiper arms so that
they do not touch the hood.
2. Remove the hood seal and cowl cover.
3. Disconnect the 5P connector (A) from the wiper motor (B).
4. Test the motor by connecting battery power and ground according to the table. If the motor does not
run or fails to run smoothly, replace the motor.
5. Connect the battery power to terminal No. 1, and body ground to terminal No. 2 of the 5P connector.
Then connect an analog voltmeter between
terminal No. 1 ( ) and terminal No. 5 ( ). When
the park switch makes contact, the pointer should
swing. If not, replace the motor.

1. Remove the right inner fender (see page 20-171).
2. Disconnect the 2P connector (A) from the washermotor (B).
3. Test the motor by connecting battery power to terminal No. 1 and ground terminal No. 2 of the
washer motor. The motor should run.
If the motor does not run, or fails to run smoothly, replace it.
If the motor runs smoothly, but little or no washer fluid is pumped, check for a disconnected
or blocked washer hose, or a clogged washer
motor outlet. 1. Remove the right inner fender (see page 20-171).
2. Disconnect the 2P connector (A) from the washer
fluid level switch (B).
3. Remove the washer fluid level switch from the washer reservoir.
NOTE: Fluid may flow out of the opening.
4. Check for continuity between terminals No. 1 and No. 2 in each float position.
There should be continuity when the float is down.
There should be no continuity when the float is up.
5. If the continuity is not as specified, replace the switch.
