If you have a telescoping steering column, see if retracting it (pushing it closer to the dash, away from the driver) makes any difference. Sometimes the electrical harness to the clockspring is stretched *just* a bit too far when the wheel is fully telescoped towards the driver.
It's been a while since I've had it apart, but I think that the cruise control lever is on the "back" side of the clockspring, closer to the dashboard, while the horn, airbag, and steering wheel audio controls are on the "front" side of the clockspring and have to pass through it to work. That's probably why the cruise control still works. If retracting the steering column doesn't fix the problem, I'd suspect a bad clockspring.
