92 cutlass supreme horn problems

i just recently bought a 92 oldsmobile cutlass supreme for my first car. it has this problem where if you hit the steeringwheel to hard the horn goes off, it does this even if you just tap it lightly. is this something i could fix myself or would i have to take it to a shop? im guessing theres a problem with the electric system but i dont know, any help would be great. thanks

The front cover of the steering wheel just pops off. Replace the horn switch with one from a j/y.
