TICKING NOISE IS COMING FROM FRONT RIGHT UNDER THE HOOD

Near the headlight from a small piece that's connected near these aluminum tubes It's a small plastic square block w two wires coming out the top that plugs straight down into its place. Im not sure what it is or what its function is. However, it makes a consistent ticking sound at all times while the motor is on.

You can feel a tapping/knocking feeling when touching this piece. Can you explain to me what this part is, its function, the cause of it clicking and if this is a major or minor problem and if replacing it is costly? Also how to replace it if it is faulty. Thank you very much!

Do you
have the same problem?

Sounds like you're talking about a relay however we don't know what it ties to-Is everything within the electrical system functional? Give us a picture on it-so we can identify-If you wish try replacing it and see what happens
