One problem related to air bag on-off switch has been reported for the 1997 Plymouth Grand Voyager. The most recently reported issues are listed below.
I got in the van in my driveway and turned the ignition switch on then I noticed that the air bag light was on. So I turned the ignition switch off waited a minute then turned it back on and the light was still on. I thought it was a fuse so I proceeded to my destination. As I arrived at my mom's house I tried to blow the horn, then I found out that my horn did not work. So I turned the van off and I called a friend who is a mechanic and he asked me if the air bag light stayed on even after I turned the van on and off I said yes then I explained everything to him. He told me that I needed to try my cruise control. And if it did not work then my clockspring is gone. Well cruise control did not work. And the airbag light is still on.
