Windows car Mazda 3

Using pulse signals from the proximity switches on the Hall sensor in the power window motor, the power window control module in the power window main switch determines the position of the window and the direction of movement of the window

Accordingly, the main switch controls the power window servo system on the driver's side.

When the home position is set before the vehicle is handed over, the window glass position and direction of operation are stored in the control module in the power window master switch.

Adjustment of the home position is therefore necessary if the cable is disconnected from the negative battery terminal, the main switch connector or the power window motor connector.

If the home position has not been set, then the functions of the automatic operation of the driver's side power window system, automatic window return and fine movement will not be available.

Power window motor

The power window motor is equipped with a connector and a gear.

1 - electric motor; 2 - connector; 3 - gear; 4 - proximity switch on Hall sensor No. 1; 5 - proximity switch on Hall sensor No. 2; 6 - shaft; 7 - magnet; 8 - low; 9 - high; 10 - impulse (proximity switch on Hall sensor No. 1); 11 - impulse (proximity switch on Hall sensor No. 2); 12 - one revolution of the power window motor with a servo drive; 13 - detection of glass movement distance; 14 - up; 15 - down; 16 - detection of glass movement direction

Two proximity switches on the Hall sensor are installed in the socket.

The hall-sensor proximity switch uses a set of magnets on a rotating axle to sense the rotation of the power window motor and outputs a synchronized pulse to the main power window switch.

The proximity switch on Hall sensor #1 emits one pulse per rotation of the window motor shaft.

Accordingly, the power window main switch determines the angular speed of rotation of the electric motor.

The main switch determines the direction of rotation of the power window motor by the difference between the highest and lowest points of the pulse from each proximity switch on Hall sensors No. 1 and 2.

Door lock servo system

Wiring diagram of the door lock remote control system: 1 - dome light for the engine compartment; 2 - trunk lid lock switch; 3 - front door lock switch (left); 4 - front door lock switch (right); 5 - rear door lock switch (left); 6 - rear door lock switch (right); 7 - ceiling lamp for lighting the luggage compartment; 8 - the switch of draft of blocking of the lock of a door; 9 - front door lock cylinder switch; 10 - trunk lid lock cylinder switch; 11 - tailgate lock switch; 12 - instrument cluster; 13 - microcomputer; 14 - door lock relay; 15 - with double circuit function; 16 - double circuit relay; 17 - door unlock relay; 18 - relay for unlocking the trunk lid; 19 - remote control door locks; 20 - front door lock actuator (driver's side); 21 - front door lock actuator (passenger side); 22 - rear door lock actuator (left); 23 - rear door lock actuator (right); 24 - tailgate lock actuator; 25 - tailgate lock actuator; 26 - front direction indicator (left); 27 - side direction indicator (left); 28 - front direction indicator (right); 29 - side direction indicator (right); 30 - rear direction indicator (left); 31 - rear direction indicator (right); The control unit and the door lock timer unit are combined

The radio transmitter is equipped with a button to turn off the alarm sensor.

The lock cylinder switch is located in the door lock retainer.

Removing and installing power window regulator

Disconnect the negative battery cable.

Remove the front door/rear door glass.

Remove the front door/tailgate speaker.

Remove the power window motor.

Remove the nuts (fig. 3).

Insert your hand through the speaker hole, rotate the regulator drum housing in the direction shown in Figure 4, and separate the regulator drum housing from the door unit mounting hooks.
