'93 LeSabre intermitted air bag light
 

Got into the LeSabre yesterday and drove it about 50 miles. During the whole trip the Air Bag light would come on for a few seconds, then go off. This would repeat randomly... sometimes every minute sometimes not for 10+ minutes. It was rainy and I'm suspecting a loose wire or something exposed to the wet. The weather is good today so I'm going to try and take it out and see if it is still happening.

Is there a way to get the airbag error codes without an OBD-I reader? Troubleshooting would be a lot easier if I had an idea as to what sensor was causing the issue.

Anyone have any troubleshooting hints?
