Is it the blinker switch?
 

Last year I had a problem with my windshield wipers randomly turning on, but it was usually when I used my blinker. And it only happened in cold weather. Now it does it all of the time when I use the blinker OR turn the steering wheel. I have no idea why turning the steering wheel would trigger the wipers to rotate but it seems like it does. So am I needing an entire new switch/arm? Electrical problems piss me off.

Yea Kevin thats what it sounds like. You will have to replace the multi-funtion switch. Its not hard to do. Helpful hint, use the factory OEM part. Good Luck

Found this, maybe this will help

Thanks man, I'll try that.

didnt i tell you this. lol.

You just said buy a new blinker switch, and they're like $60. lol

you probably switch the nob and u turned the blinker on lol

Well I cleaned and greased the contacts, but it still does it. My brother noticed one of the wires (The blue one I guess) is crimped, so he wants to pull the switch out and rewire it.

i said its the blinker switch, buy a new one. lol.

But I gotta buy a head unit and a new battery. And tint. lol

Your car is possessed, you just need an exorcism!! A priest and some holy water and she'll work just fine. You'll have to name her Linda now.

Lol, dude that sucks. So every time you turn your wipers go off too?
