4. Test the motor by connecting battery power to the No. 2 terminal and grounding the No. 3 terminal of

the wiper motor 5P connector. The motor should run at low speed. If the motor does not run or fails to
run smoothly, replace the motor.

5. Test the motor by connecting battery power to the No. 2 terminal and grounding the No. 5 terminal of

the wiper motor 5P connector. The motor should run at high speed. If the motor does not run or fails
to run smoothly, replace the motor.

6. Connect an analog ohmmeter between the No. 1 and No. 4 terminals, and run the motor at low or high

speed. The ohmmeter should indicate continuity and no continuity alternately. If it does not, replace
the motor.

WASHER MOTOR TEST

1. Remove the right inner fender (see FRONT INNER FENDER REPLACEMENT ).

2. Disconnect the 2P connector (A) from the washer motor (B).

NOTE:

Carefully remove the wiper arms so that they do not touch the hood.

3. Test the motor by connecting battery power to the No. 1 terminal and grounding the Non terminal 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.

WIPER MOTOR REPLACEMENT

1. Open the hood.

2. Remove the caps, nuts (A), and the windshield wiper arms (B).
