Open the hood and remove any plastic covers or panels obstructing access to the wiper motor.
Disconnect the battery to prevent electrical shorts.
Unplug the wiring harness from the wiper motor.

4. Test and Replace the Wiper Motor (if necessary)

Using a multimeter, test the motor for continuity and proper voltage.
If the motor is faulty, remove the mounting bolts and lift the motor out.
Install the new motor by reversing the removal process. Ensure it is securely mounted and correctly aligned.
