THEORY OF OPERATION
If either one of the Window Driver circuits are open, the motor will be totally inoperative. To lower the window, voltage is applied to the (Q21) Window Driver (Down) circuit and the (Q11) Window Driver (UP) circuit remains grounded in the module. To drive the window up, the circuits are reversed.

The window motor contains a hall effect sensor to detect the window position. A hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. If the motor looses its counts, it may perform erratically or in very short movements.

The mirror position sensor is used in conjunction with the memory system. Anytime the mirror changes position, the sensor changes its value. That value is stored in the door module. When a command from the memory set switch is received, the module will position the mirror to the exact position chosen by the particular driver.

The memory system is able to store and recall all exterior outside mirror positions. The system can be set for two different drivers. The memory mirrors have a variable resistor (potentiometer) that measures the resistance of the vertical and the horizontal position of the mirror. This value changes anytime the mirror is moved.

The Mirror Vertical Driver circuit supplies battery voltage for the mirror up position and ground for the mirror down position. The Mirror Common Driver supplies battery voltage for the mirror Down position and ground for the mirror up position.
The Mirror Horizontal Driver circuit supplies battery voltage for the mirror left position and ground for the mirror right position. The Mirror Common Driver supplies battery voltage for the mirror right position and ground for the mirror left.
The express up feature is accomplished by the door module sensing the exact position of the window at all times. This is done by the module reading the counts of the hall sensor located in the window motor. Whenever the module looses track of the window position, it will not allow the express feature to operate and will set this DTC.
