I've looked through a lot of posts and haven't come across my specific problem. My windshield wipers do not come on when I pull back to mist my windshield. I know some civics don't come with this option but here comes the strange part. If I turn my headlights on and mist the windshield the wipers come on and do their thing??? Also while the headlight switch is in the off position the seat belt warning buzzer doesn't sound but when turned on it works. I tore down the dash to see what I could find and found nothing. I'm going to go back out tomorrow to trace wires again in attempt to find some kind of short or something. Please let me know if you've ever came across this problem or have any ideas.

 

Sounds like a bad ground wire.

The DX did not come stock with the mentioned wiper option.

 

I agree with Ron, the civic's from 96-2000, I've never seen them automatically wipe when the mist is activated. Sounds like some electrical troubleshooting is required here because someone before you messed with it.
