(1) There is 
malfunction in 
the wiper 
switch. 
(2) There is 
damage in the

(1) Check the 0 
position contact of the 
wiper switch. If it is 
poor contact, replace 
it. 
(2) If the contact 
works properly, check 
the automatic stop 
conducting strip 
installed on the back 
of the worm output 
shaft of the speed 
reducer, and 3 
conducting contacts 
installed on the cover 
of the speed reducer. If 
they are defective, 
replace them.

(1) Ignition switch. 
(2) If the ignition 
switch works properly, 
then verify that the

washer motor. 

The washer 
functions, but

the wiper does 
not function. 

The intermittent 
controller of the 
wiper is 
defective. 

The washer functions, 
but the wiper does not 
function, it is mainly 
because a malfunction 
in the wiper 
intermittent controller 
results a circuit open 
to the wiper motor, so 
the wiper cannot 
function. Replace the 
wiper intermittent 
controller.

ELECTRIC WINDOW REGULATOR SYSTEM 

SYSTEM DESCRIPTION 

The Chery sedan A15LHD employs an electric steel wire type window regulator. The 
structure is shown in figure (window-1). 

 

Electric window regulator (window-1) 

                                         

The up/down operation of the window can be centrally controlled by the driver through 
pushing buttons, and also can be controlled individually by the door switch to adjust the door 
window opening. The mechanism transmission route is as follows: motor → speed reducer → 
steel wire roller → steel wire → window supporting bracket → window up/down. The 
control module is installed under the left-hand rear seat, as shown in the figure (window-2).

FAULT DIAGNOSIS AND TROUBLESHOOTING 

1. THE ELECTRIC WINDOW CAN NOT BE ACTIVATED 

When the electric window can not be activated, the followings should be checked: 

(1) Whether the voltage of the battery is normal; 

(2) The voltage supply of the thermo-sensitive fuses and the control relay; 

(3) The window regulator switches and the voltage supply, including the front left, front right, 

rear left and rear right windows; 

(4) The contact switches of each door and motor signals; 

(5) The working current of each window regulator motor; 

(6) The function of the mechanical linkage device for each window regulator. 

2. THE ELECTRIC WINDOW REGULATOR DOES NOT FUNCTION 

When the electric window regulator does not function, the followings should be checked: 

(1) Whether the voltage of battery is normal; 

(2) Whether the security switch (installed at the front left armrest) was depressed; 

(3) Whether the circuit between the rear window regulator and the security switch is open; 

(4) Whether the rear window regulator motor and the mechanical linkage device are jammed; 

(5) Whether the security switch and the control push buttons are ineffective.
