GM Fuses

How Faulty Fuses Affect Vehicle Reliability

Fuses are safety devices that are designed to "blow" and interrupt power during an electrical surge to protect expensive hardware. A single failed fuse can lead to mysterious issues like a non-responsive infotainment screen or a sudden loss of power steering. Because electrical shorts are often caused by mechanical friction, it is important to also check key engine parts for any wiring harness interference.

Easy Steps to Identify and Replace Blown Fuses

Whether you drive a Chevrolet Equinox or another model, use the following guidelines to diagnose a blown fuse:

1. Identify the Failing System

Note which electrical component has stopped working, such as the radio, interior lights, or the 12V power outlet.

2. Locate the Fuse Boxes

Consult your Equinox manual to find the locations of the interior fuse panel and the main under-hood power center.

3. Use the Fuse Map

Look at the diagram on the inside of the fuse box cover to find the specific fuse number and amperage for the failed system.

4. Use the Puller Tool

Always use the plastic fuse puller tool provided in the box to remove the fuse without damaging the surrounding terminals.

5. Inspect the Internal Bridge

Hold the fuse up to a light; if the metal wire inside is broken or there is a dark scorch mark, the fuse is blown.

6. Replace with Identical Amperage

Insert a fresh genuine GM fuse of the exact same color and amperage rating to restore power safely to the circuit.
