I just put a new battery in my LX and it still won't start. I listened for sounds, no clicks. All of the dash warning lights, headlights, radio, and even AC come on when I turn the key, but no vroom vroom. Strange thing is the hazards lights start blinking and won't go off, not even when I turn the car off. After wiggling the turn signal stick a little and pressing the hazard button in a few times it cuts off. But when I open the door of the car the hazards come on again, and are accompanied by ding ding sound like when door is ajar--even after door is shut. I was thinking electrical problem

Brake lights and turn signals don’t work. Tail lights stay on no matter what position the light switch is in

So Iam getting nothing from my instrument cluster in my 2003 civic lx coupe. It hasn't worked since a lady tried to give me a jump at the store almost a year ago. She put the cable on backwards. Since then I replace the ECU, ignition switch, starter, alternate and the fuel box under the hood. But I've also tried another cluster altogether and still nothing but blinkers and hazards. Anyone got any ideas?
