Headlight/blinker/horn question

Hey Boys:

Im not to sure what the hell I did but heres the problem. Im having a problems with my horn, headlight button (button that controls the headlights from going upnand down), and my turn signals do not work. Funny thing is the lights in the interior work, the lights on the headlight work. Hopefully someone can give me some advice on what I messed up.

Have you checked all the fuses?

i had it once with turn signals and it was one of the 7.5 A fuses

check the relays and resistors

yea check the fuses in the engine bay, its by the battery, little black box. It contains fuses for ignition,headlight, horn, etc.

is the battery connected?

if so then id check all the fuses if there all good then id look to the grounds
