1. An apparatus to control a wiper position, comprising:
- a controller to receive a wiper operation control signal output from a user input unit to control a wiper to be stopped at a desired position;
a wiper motor to drive the wiper;
a wiper relay switched to drive the wiper motor under a control of the controller; and
a wiper sensor having a parking switch to sense a position of the wiper motor according to an open signal and a ground signal of the parking switch to transfer a position signal to the controller,wherein the wiper motor is divided into a plurality of sensing sections at which different resistances are set and receives different voltages at the respective sensing sections.
