Wiper motor connector
Examination
1. If the brush stroke is too slow, check the condition of the battery. If the battery is fully charged, then remove the wiper motor and check by hand for free movement of the brushes. Lubricate all pivot joints or repair as necessary. If this measure fails, then check the condition of the contacts, especially the ground connections. If all connections are good, replace the motor.
2. If the wiper does not work, check the fuse. If the fuse is good, then connect the electric motor to ground with a separate jumper. If the electric motor turns on, repair the ground connection. Otherwise, turn on the wiper and disconnect the motor connector. Check the presence of voltage on the electric motor. If there is voltage, check the motor.
3. For access to conclusions of a back screen wiper remove facing panel of a door of a cargo compartment.
