One problem related to air bag light on has been reported for the 2003 Chevrolet Blazer. The most recently reported issues are listed below.
My 03 Blazer has had its airbag lights on for some time now and I'm worried that if I get into a crash my airbags wont deploy, I'm scared also to see so many complaints along the same lines as mine. This problem needs to be addressed by the NHTSA or by gm before someone is killed or injured badly. A recall is needed!.
