Default Wipers come on when honking horn?

hey guys, from what i know, the horns short out. When i either honk the horn, or use my left turn, the wipers come on. When i unpluged my horns, either one, my wipers cam on instantly. Anyone else run into this? thanks Len

OE horns are a waste of engineering on vehicles... if you want a horn do what the doc said... install one that counts that wya the peple that know how and when to use them are the only ones that are able to install them... it'd cut donw on abunch of button happy people out there... now only if signal lights were as popular...

btw, sounds like a possible ground problem... grounds can do some real odd things. find a wiring schematic find the common ground... clean it up see if it fixes it... if not look into a clock spring

maybe one one is playing a joke on you?

you can make the horn sound when the blinker blinks or every time you press on the brakes with just diode
