　　If vice water motor does not rotate, the possible reasons have wiper circuit and switch circuit, wiper circuit fuse fuse, motor damage, such as maintenance and repair method is as follows.

　　1) check whether the fuse is normal, line presence of break off, if the fuse cutout, replace the fuse of the same specification, and check the relevant circuit for fault; If a line is loose, good line: if the fuse and wiring all normal, for the next overhaul e

　　7) check the wiper switch, whether the contact is poor contact. Vice water can be switch short circuit, see if we can work, vice water if wiper can work, for the wiper switch is faulty. Need maintenance inside the switch contacts or replace the wiper switch; If the wiper still cannot work, for the next overhaul.

　　(3) gun to check the resistance of the wiper motor, to determine whether the internal circuit or poor contact, or directly connected to the 12 v power supply to see its rotation, if not normal, replace the motor. Car fixture

　　If the wiper motor rotation, but wiper blade dynamic constitutive articulated point loose, need to repair or replace the drive gear.

　　2. Wiper blade swing troubleshooting possible causes of low speed drive mechanism connecting rod has a loose or drive motor

　　If the wiper wiper blade swing speed significantly below normal circumstance, the possible reasons there are two aspects of electrical and mechanical, maintenance and repair method is as follows.

　　1) check whether the power supply is normal, but through the way of the headlamps or by electric horn inspection whether the power supply voltage is too low, if the headlamps dim or electric horn sounds kid, need to repair the power supply circuit, the status of the generator and regulator, electric storage oil; If the power supply voltage is normal, check the vice water motor wiring connection for loosening and fever.

　　Pet-name ruby in good situation, wiper power circuit to check the wiper blade and wind secretly glass contact condition. Special piece of rocker arm stand, in the case of no resistance to look on the swing speed is normal. If the normal, wipe the wind window and wiper blade surface or replace the wiper blade; If still not normal, it need to repair or replace the motor.

　　3. Wood working noise of troubleshooting

　　Wiper work noise from three aspects:

　　Wiper blade and the wind main glass scratching noise. Because the wind main glass is dry or smudgy wiper blade oscillation property to have noise, need to clean the wind window, or replace the wiper blade.

　　(2) the noise transmission mechanism movement. Transmission mechanism of friction during a job or bruised, need to repair or replace the drive gear.

　　(2) the motor working noise. When the motor work, there is abnormal sound, need to repair or replace the motor.

　　1. The troubleshooting of washer does not work

　　Washer does not work, Jane first check lines have yuan break off, whether the fuse burn out. If the connection lines and fuse are normal, then pull out the plug washer motor, when the washer to switch with 12 v dc voltmeter or test pencil denier plug power terminal voltage measurement. If the voltage is normal, need to repair or replace the washer motor; If no voltage, or replace washer switch shall be checked.

　　If just do not spray scrubber, nozzle or pipe jam, should be smooth, and clean scrubber tank, replace o washing liquid

　　2. The scrubber water pressure is too low

　　If scrubber water nozzle, the hydraulic pressure, should check and dredge hoses, washing pump, if the spray pipe road unblocked after hydraulic force is still insufficient, you need to repair or replace the washer motor.

　　3. The scrubber troubleshooting intermittent work

　　Scrubber and sometimes work, sometimes does not work, this is usually caused by poor circuit connection and switch, should first check the washer motor wiring and washer switch, if all normal, cleaning, washing scrubber pipeline pump is needed. And change the washing liquid.

　　4. Troubleshooting defroster don't work

　　Defroster don't work, should check whether there is any broken on line first, whether the fuse burn out. If the line connection and fuse are normal, the defroster switch short-circuit, whether the defroster defrost. If still can't defrost, need special 7: maintenance defroster grid wire; If can defrost, the need to repair or replace the defroster switch.
