Electrical problem?

I would not start replacing parts untill a bit of diagnosis is performed. I suspect the switch is operating normally since you stated that you hear a click noise. This typically indicates that the switch is working. Remove the door panel and check the voltage at the black and yellow wire at the motor connector while actuating the window switch down. Repeat the same while pressing the switch up on the oragne and yellow ire. If you have voltage, then the motor has failed.
