Where is the ecm on a 94 Chevy s 10 blazer?
The ECM (Engine Control Module) on a 1994 Chevy S-10 Blazer is typically located under the hood, on the passenger side fender well. However, its exact position can vary slightly depending on the engine and options. It's usually a rectangular black box with multiple connectors. You might need to remove some plastic covers or trim to get a good view.
