Solution of rear wiper not spraying water
If the car can't spray glass water, first check whether the water pump motor works. If not, check whether the insurance is burnt out, whether the line connection is reliable and whether the water pump motor is burnt out. Check whether the water pipe is broken, whether the joint falls off and whether the nozzle is blocked. If the water pipe is broken, it needs to be replaced and reconnected. The nozzle can be dredged with thin wire.
If there is water in the kettle and the motor is working, you can unplug the nozzle and press the spray switch. When water is sprayed from the water pipe, the nozzle is blocked and can be opened with thin iron wire.
