Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The horn switch and the cruise run through a spiral connector at the base of the steering wheel called a clockspring connector. When the connector fails the signal form the switches can't get to the relay and computers that need input to give the desired output.
Replacing the connector is the solution and to do this the steering wheel will have to be removed
The removal is shown here
The part is called a slip ring in the procedure, a cable reel in the wiring diagrams and a clockspring by the trade

There is a relay mounted under the hood that the horn switch grounds and the contacts in the relay close connecting power to the horn at the front of the vehicle. I would have you troubleshoot the horn circuit by checking the relay operation but you say the cruise control does not work either and those switches run through the clockspring as well.
Is your airbag light on?
Yes it would as the primary reason for the clockspring is to keep a constant connection from the airbag to the wiring harness as the steering wheel is turned
What are the names of the parts that I would need. Can I get these parts from an Aftermarket Store? I do not want to go to the dealer. Dealers are too expensive and I'm on a tight budget. Please help me.

The part you need is the clockspring/cable reel/slip ring assembly. The airbag will have to be removed so it will have to be handled with care as it can kill you.
I don't see any source for the clockspring, at 18 years old the dealer may not have one for you either but you might try car-part.com for used ones in your area. You can always try a used one but if the car is wrecked it is likely broken as well.
The horn can be wired to an aftermarket horn button mounted on the side of the steering column or the dash board. I don't know if you have a safety inspection where you live but this method will not pass inspection.
If that is not an issue the a horn button is available at any autoparts store for about $5. Ground one side of the switch to a good body ground and find the horn switch wire at the base of the column in the harness and attach it to the other side of the switch. When you push the button it will connect the horn wire to ground and the horn will blow.
The horn wire is blue/red and is in cavity 4 of connector at the base of the column. You can back probe the connector with a pin or needle and use a jumper wire to touch ground to be sure you have the correct wire.
