1. Remove windshield wiper arms and scoop type air intake (see below).
2. Disconnect the 5-pin connector from the windshield wiper motor.
3. Apply voltage from the battery to the contacts as shown in the figure, and check if the e/motor rotates smoothly without abnormal sounds.
If an abnormal sound is heard or the e/motor does not rotate smoothly, replace the e/motor.
The measurement is carried out by an analog tester (measuring range 0-15V).
