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.
