What is this?!?!?
Relays do that when they're working.
Think of a relay as a heavy duty switch, that is activated using a lighter duty switch. Like that you can control high amp items with low amp switches and wiring.
The sound is a circuit being closed, or opened. Completely normal.
Is anything not working on the car as it should?

As stated above relays clicking things on and off like a light switch is normal. However, if it's a rapid ticking/clicking it could be an a fault in the relay or low battery voltage.
Telling us what relay this is or taking a picture of where you pulled it from is important. Also, how often is this clicking? Is it intermittent, rapid and constant, slow and steady? Descriptions will help someone determine if it's normal when they listen to theirs for you.
Also, as stated above, is there anything that used to work that isn't? Let us know

then you probably have ground issues on that circuit to the control side of that relay. a buzzing relay is likely an issue with the control(coil inputs) portion, you need to find what is constant and what is cycled(power or ground) via the inputs and test them both accordingly. something less than 7v on the positive control side of the relay would cause issues, as well as high resistance on the ground side(something over 50 ohms). you can test the relay itself by taking a 12v battery and using it to power up the relay to test the coil.
relays aren't extremely complicated to test and rule out, the coil is labeled inside the connection by the pins, i can see in the picture so you already have a pinout for it, apply 12v to one of the coil pins and ground to the other, a single click and less than 10 ohms across the com and no pins means the relay is good.
