1999 Dodge Caravan Possible Steering Column Issues

My Caravan has a lot of miles but seems to keep going. Last Summer it started having problems with cam position sensor(changed twice) transmission sensor of some sort(fixed), flashing lights in the a/c, heating controls(fixed) and now it has no horn, cruise control, or windshield wipers and the air bag light is on. There hasn't been any front end damage before this started.
Any suggestions?
