Car goes haywire when I connect the battery

Asked by Oct 03, 2016 at 11:40 PM about the 2014 Chevrolet Silverado 1500 LT

Question type: Maintenance & Repair

I replaced the batter in my truck, the
positive was loose and when I wiggled it it
popped off and sparked a little, now when I
reconnect the battery the horn goes off
and won't shut off and the wipers move
and spray continuously. Along with the
headlights flashing (the engine turns on)
but the symptoms won't go away. Would it
be a fuse that went out and if so what
fuse?

The horn blowing and the light flashing is the security system, read the owners manual on how to turn it off, the wiper problem could be a error in the body control module, on late model v hi let's if you loose battery power the factory presets go away and the system has to be reflashed by the dealer to get them back.
