switch. If the warning 
lamp is off, it indicates that 
the warning switch of 
coolant temperature is 
faulty; If the warning lamp

ELECTRIC WIPER AND WINDSHIELD WASHER SYSTEM 

SYSTEM DESCRIPTION 

The wiper is mainly consisted of the wiper motor assembly, the three-linkage mechanism, 
and the pendulum rod and wiper blade with the tri-directional flexible ball joint. See figure 
(wiper-1). The wiper motor is shown in figure (wiper-2). 

 

 

Wiper 

 

1. Permanent magnet DC motor 
2. Worm-gear speed reducer 
3. Wiper motor output shaft 

 

 

 

                    Wiper motor（wiper-2） 

The wiper motor is a speed reducer comprised of a mini permanent magnetic DC motor and a 
worm-gear. In order to ensure that the pendulum rod and wiper blade could be positioned 
under and parallel with low end of the front window each time after it has stopped. An 
automatic stop conducting strip is installed on the back of the worm output shaft of the speed 
reducer and 3 conducting contacts that contact with the conducting strip are installed on the 
rear cover of the speed reducer. The strip and the contacts jointly perform the automatic stop 
function together with the contact of the 0 position of wiper switch.

The washer is consisted of 5 parts which including a mini permanent magnet DC motor, 
centrifugal water pump, nozzle, liquid storage container and water pipe. The motor and water 
pump make up the assembly of the washer motor and the water pump as shown in figure 
(Wiper-3):

2-Impeller blade 
3-Pump body 
4-Water outlet 
5-Permanent magnet DC motor 

Washer Motor（wiper-3) 

As shown in figure (wiper-4), this assembly is installed on the liquid storage container and 
make up the washer assembly together with the liquid storage container. The washer 
assembly is installed on the left-hand impeller blade and the capacity of the liquid storage 
container is 5.1 L.
