My horn died so I'm trying to replace it but I can't locate it

Acende a luz de check engine, abs e indicador do freio de mão. O velocímetro para de funcionar. O que fazer para corrigir o problema?

Issues with the wipers turning on. Changed the fuse, and still nothing. Could it he the motor? if so, can anyone point me in the right direction to purchase one. And what to buy.

I have this blue thin wire next to my alternator and I don’t know where exactly it goes. Hence my battery light is on

Turn the key to start and nothing happens. Battery is good and charged.
