ok so i was at work when a co worker was nice enough to tell me that my lights were left on... i figured interior lights since its impossible to leave your headlight on by accident in our cars... well i was wrong.. my headlights were on... i turned them off and figured the switch to turn them off (ground point at driver door) must have stuck whenever i opened the door and the lights didn't turn off... no big deal... well now here comes the problem

i parked my car at home and three hours later went out to find my headlights on and my windshield wipers going... the car was not on.... i turned the car on and turned off the lights but the windshield wipers keep going... and going and going... turning the switch does nothing... i even disconnected the switch at the column and pulled the fuse and they still keep on going... obviously there is a short somewhere... anyone have any ideas... i tried to trace it the best i could but its so hard with all the snow here.... please help with any ideas!! i don't see any pinched wires in the steering column near the switch...

yea this is the same exact thing thats happeneing to my car right now...when i pull the wiper fuse, everything works as normal, if i put it in, the ding noise starts like i have the keys in the ignition but i really dont, my handbrake light goes on, the wipers go on, and a few other things. im pretty clueless when it comes to wireing but im glad dustin said something about that leaking, im going to check that out when i get a chance but that more then likely sounds/looks like the problem...its weird this is poping up all over all of a sudden....
