There is not a relay in the system. It is probably the circuit breaker making that sound. The motor is overloaded and drawing too much power so the breaker cuts it. To test it out, take the door panel off, roll the window up and down until it is acting up, unplug the power window motor, and use a volt meter or test light to confirm that it gets power when you hit the switch up and down. If it is getting power, then you need a new motor. Let us know what happens.
