96'Plymouth Grand Voyager air bag light, no horn, no cruise

Sounds like the clockspring

This is some kind of ring placed by the steering wheel that is broken in your car. This is free to fix at your car dealer, because this part is bad from the beginning and this happened to me also a year ago. My car dealer fixed this for free because this was a guarantee case they said, and my car is old(1996 model), and still it was free to repair. Did not pay for work hours or part. :)

Most likely the clockspring. Have the dealer doublecheck your VIN for a recall for this problem. I think 96 is too early for the recall but it's worth looking into just in case. The older square models had a similar symptoms but the case of the airbag light was a locked up rear wiper motor - the're on the same circuit and the wiper motor pops the fuse. There was a recall on some of those models as well.
