I was walking through my garage just now and as I walk past my car I hear a repetitive clicking noise. I opened the door and the noise stopped so I got in the car and closed the door. After about 30 seconds it started clicking again and again. I believe I’ve narrowed the noise down to the fuse box. I pulled the #8 fuse and it didn’t stop but as soon as I put it back in it quit and didn’t do it again. I believe I found the reason why my battery slowly drains. Any ideas?

That's probably the sound of a circuit breaker tripping open and the resetting

See fuse panel slot #2 and #14 on the diagram below.

I agree. Pull the circuit breakers and see if the noise stops
