Howdy. I'm new here. My wife’s' 03 Civic EX has turned into Christine and developed a mind of its own. The car has about 15k miles and it has some serious electrical issues. Today the power door locks stopped working, the intermittent wipers don't work with the switch although the wipers will move on their own with the switch in the off position. When you hit the power door lock switch, the instrument cluster lights will flash on and off. When you turn on the emergency flasher / hazard switch, there is a buzzing noise from under the dash. The turn signals don't work, the indicators on the cluster will not even light up. The power windows work intermittently. Has anyone else had electrical issues with their 2003 Civics? The car is at the dealer now and they gave me a loaner CRV to play with until her car is fixed.

Your body control module is probably dead. I got an 2003 LX. I got an engine component replaced. Nothing as severe as your problems.

Or.... look for a loose ground connection. Honda connects all the wire harnesses to common ground points. There are some under the hood, and under the dash. There's also one in the trunk, but you don't seem to have problems there. I'd check all the ground points before doing anything else. It'll be a bolt with a bunch of wires under it.

Ok, the car has been fixed. The dealer called on Monday and said it was the multiplexer control unit and it would take two days to get the part. The part came in on Thursday and the dealer installed the multiplexer and that didn't fix it. Apparently, there was a loose ground connection under the bumper but they didn't tell me if it was under the front or rear bumper but they said they had to pull the bumper off the car to get to the ground point. Thanks for the replies about this issue. I hope this helps someone down the road.

HAH! Loose ground does it again!
