Theory Of Operation
If either one of the Window Driver circuits are shorted to battery, the motor will operative in one direction only. If the current remains on when the window is in its full travel, the circuit breaker will open. 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.
