I own a 2002 Ford F-150 XLT 5.4L today I was putting in the seats because he carpet got wet and had to be dried. I had my headphones in my ears but after screwing in the last bolt for the driver seat I heard a clicking noise took my headphones out and heard a clicking in the fuse box under the steering wheel along with the interior lights flickering on and off at a steady pace. I realized that one of the relays is making a clicking noise along with the lights going on and off when I put the key in the dash lights flicker and my radio doesn't seem to work this only started happening a few hours ago. If anyone has any ideas or have dealt with this before I could really use some help.

I had a similar clicking noise/interior lights flickering once when I was installing audio wires under the carpet. I undid a factory ground under the passenger kick panel and that's what did it. Look around for loose/frayed/shorted wires. Might have hit something while working with the carpet.

Alright thanks for the help will look again tomorrow in the morning.

Yep. What he said. If your relays aren't blowing; then it's probably a minor short. Might be hard to track down; but make sure your connections are strong.
