I have a 99 z28 camaro and every time I use the wipers it mists. I‘ve tried every setting there is, and they will not go off. I‘m in California so it doesn‘t get freezing, but its cold enough at night right now that my car is always wet passed 9pm or so and I can‘t see!! It‘s not the inside, but my windshield doesn‘t have a chance to be dry because of the mist so it‘s always foggy. This is so frustrating, please help!
the wiper switch has gone bad, replace it. in order to stop them from going all night, just pull the fuse for now. its located behind the firewall on drivers side dash if you are mechanically inclined. as long as it's not raining, you can just leave the fuse out until you get it in to a mechanic.
If you still want your wipers, pull the wire harness that plugs into the side of your windshield washer fluid reservoir until you can service your camaro.
