One problem related to dash wiring has been reported for the 1999 Honda Accord. The most recently reported issues are listed below.
Short in the electrical system. The dashboard clock light went out, followed by the ac adapter. About 2 months after the adapter went out (working spuratically) the driver's side power locks stopped working when the car is off and/or the door is opened. I also have a "check engine" light come on when there is nothing wrong with my engine.
