LH Front Power Window Switch

The LH front power window switch provides switches for controlling all of the power windows. This switch also has a lockout button, which the driver can use to prevent the other window switches from functioning. The switch passes switching information to the Driver's Door Module (DDM) by way of the Simple Bus Interface (SBI). Battery voltage and ground are applied to the LH front power window switch from the DDM through circuits 1729 and 226 respectively.
