hey all
I just bought a 93 integra ls 4dr. great car i noticed when i was checkin everything out on it that the rear defroster button doesnt work, the horn doesnt work and the cruise control doesnt work. i checked all the fuses and all the related ones were blown. when i put new ones in the blew too. i know there is the cable reel inside the steering wheel and im going to check that, how does that reel work is it just a plug? also what are some ideas on the defroster it lights up when you press the button just doesnt start melting anything

thanks for all response
