Code B1403 Description

The driver power window is controlled by the Front Electronics Module (FEM). The driver power window regulator control switch and motor are hardwired directly to the FEM. The FEM will read the window regulator control switch actuation and provide the corresponding output to the window motor. If one-touch operation is selected, the FEM powers the driver window motor for seven seconds or until the FEM senses the motor is stalled. If the window track, regulator or glass weatherstrips cause the glass to bind, the FEM may interpret this as a motor stalled condition and halt motor operation.
