DIAGNOSIS AND TESTING (CONTINUED)
• Connect the battery positive terminal with the
positive terminal of the ammeter.
• Connect the battery negative terminal with the
windshield wiper motor housing (1).
• Connect the negative terminal of the ammeter
with the windshield wiper motor (2), pin 4.
The windshield wiper motor will run at slow
speed.
Measure the amperage.
Is the value at the ammeter next to 1,5 A?
If yes, GO to 2.
If no, INSTALL a new windshield wiper motor.
2. Check the windshield wiper motor in FAST
WIPER SPEED condition (figure
ELV3201285)
• Connect the battery positive terminal with the
positive terminal of the ammeter.
• Connect the battery negative terminal with the
windshield wiper motor housing (1).
• Connect the negative terminal of the ammeter
with the windshield wiper motor (2), pin 5.
The windshield wiper motor will run at fast
speed.
Measure the amperage.
Is the value at the ammeter next to 2,2 A?
If yes, GO to 3.
If no, INSTALL a new windshield wiper motor.
3. Check the windshield wiper motor in WIPER
PARK position
Measure the resistance at the windshield wiper
motor, connector C47, between pin 2 and pin 1.
Is the resistance less than 2 ohms?
If yes, GO to 4.
If no, GO to 5.
4. Check the windshield wiper motor out of
WIPER PARK position
• Connect the battery positive terminal with
windshield wiper motor, connector C47, pin 4
• Connect the battery negative terminal, for a
half cycle, with the windshield wiper motor
housing.
Measure the resistance at the windshield wiper
motor, connector C47, between pin 2 and pin 1.
Is the resistance less than 2 ohms?
If yes, GO to 6. Repeat this test step. If yes
again, INSTALL a new windshield wiper motor.
If no, GO to 5.
5. Check the windshield wiper motor out of
WIPER PARK position
