Electrical problems on 2002 Nissan Pathfinder

The controls for the radio and cruise control on the steering wheel do not work, also, none of the horns work. I check all the fuses and replaced the Horn relay, but still no dice. Please let me know what else I may need to do or check to get everything back to normal. Thank you.

For all the problems to be related to steering wheel mounted controls it sounds like the clock spring, (also called a spiral cable or squib cable). The clock spring allows the steering wheel to be turned yet transmit a continuing electrical circuit.
