Try disconnecting the battery for 10 minutes. May reset the light--if problem persists light will come back on
Chevrolet replaced the blazer in 1995 with the Tahoe http://en.wikipedia.org/wiki/Chevrolet_Tahoe
TAke it to the dealer. They have check out charts for times when the computer doesn't set codes.
At key on it should come on for a couple second "bulb check".
I had my 200 blazer scanned an was told it was a bad fuel tank cap. I replaced it and the light is still on.
That requires an ENGINE SCANNER to do that. But you will first need to fix what is wrong are the light will come back on. Have engine scanned.
The check engine light would come on.
A 2000 Chevy Blazer is a GM vehicle. Vehicles made by GM do not come equipped with an inertia switch.
The check engine light would come on and the code stored would refer to a bad cat.
The 1997 Chevrolet Blazer didn't come with a cabin filter.
