The windshield wiper doesn't go down because it is designed to stay in the raised position when not in use. This is to prevent the wiper blade from getting stuck to the windshield or becoming damaged by debris. Additionally, the raised position allows for easier access to the wiper blade for maintenance or replacement. Therefore, the windshield wiper is intentionally designed to remain in the raised position when not in use. **

A longer windshield wiper may smear because it has a larger surface area that can accumulate more dirt, debris, and water. As the wiper blade moves across the windshield, it may not be able to effectively clear away all the buildup, leading to streaks and smears. Additionally, a longer wiper blade may not have consistent pressure across its entire length, causing uneven contact with the windshield and resulting in smudging. **

To connect the wiper motor, first locate the wiring harness for the motor. Then, identify the power and ground wires. Connect the power wire to a 12V power source, such as the vehicle's battery or fuse box. Connect the ground wire to a suitable grounding point on the vehicle's chassis. Finally, test the wiper motor to ensure it is functioning properly. If you are unsure about the wiring, it is recommended to consult the vehicle's service manual or seek assistance from a professional. **
