Hi and thanks for using 2CarPros.
The first thing I would suggest is to supply power directly to the motor to see if it works. By simply reversing polarity will change the direction of the motor and directions of the window. Since you are hearing a noise, either the motor is bad or you have a bad connection. This test will confirm if the motor is good.
Here are the specific directions for testing the motor. The attached picture shows how to run the power.
Connect the motor terminals directly to battery voltage (12 volts) and check that the motor operates smoothly. Next, reverse the polarity and check that the motor operates smoothly in the reverse direction. If the operation is abnormal, replace the motor.
If you have trouble getting 12 volts from the battery, I have used a battery charger or jumper pack for the power supply.
Let me know what you find or if you have other questions.
Take care,
Joe
