Well i was wondering should my SES light come on when first starting up the vehicle, along with all the other warning lights (Air Bag, Chack Gauges, etc.)......... The reason for this question is that in my 1997 Blazer it does not and i was wondering if this was normal, because if it is out and I did have a problem the light would not come up, right?

 

Yes, it should turn on when you start up the vehicle.
