In today's automotive industry, many features are added in power window system. For instance, Anti Trap System, with immediate reversal of the window in the event of entrapment. Thus, it gives full and reliable protection for children's hand, neck and any obstacles as well. The aim of this paper is to develop an innovative mechanism to enable the user to control the degree of opening power window position with preset position. This experiment involved design and development of PIC program, electronic circuit design and modification on existing power window mechanism. In this experiment, microcontroller PIC16F877A is applied as a medium to achieve the goal. Generally, it will control the degree opening window whenever the user or motorist required, plus anti-entrapment features on window lifting control system. Therefore the user will be able to open and close the power window within the selected position and feel free while maneuvering their vehicles.
