Why would my "fuse box" be clicking? - Car Forums and Sep 27, 2008When I turned it off it started clicking and my door thingy was dinging. My key was NOT in the switch. My husband pulled relay #13 out of the fuse box under the dash. Everything stopped then. It was burnt. we bought a new one but when we put it in it started clicking as well. With it dark and raining we couldn't fool with it very long.
