* Under the hood in the fuse box: This is the most common location. The fuse box is typically located either near the battery or on the driver's side fender well. Look for a diagram on the inside of the fuse box lid to identify the fuel pump relay. The relay itself may be labeled, or you might have to use the diagram to find it based on its function (fuel pump).
* Under the dash: Less common, but possible. Some models might have it in a secondary fuse box or relay center under the dash, usually near the steering column. Again, a diagram on the inside of the fuse box cover will be helpful.
To find it definitively:
1. Consult your owner's manual: This is the best resource, as it'll have a diagram showing the location of all fuses and relays.
2. Check online forums: Search for "1995 Chevy Blazer fuel pump relay location" on forums dedicated to Chevy trucks and SUVs. Users often post pictures and specific instructions.
3. Use a wiring diagram: A wiring diagram for your specific Blazer's year, engine, and options will show the relay's location and circuit path. These are available online through auto parts stores or repair manuals.
Important Note: Always disconnect the negative battery cable before working with fuses or relays to prevent accidental short circuits.
