The 3rd generation Equinox is equipped with standard mini blade electrical fuses which can be purchased at any auto parts store, at Walmart or online at Amazon.

A white plastic fuse puller tool should be included on the underside of the engine bay fuse box cover. If the tool is missing, you could instead use a pair of needle nose pliers with rubber insulated handles.

The first two steps are to open the hood and then move to the right (driver) side of the engine bay.

The rectangular shaped primary fuse box is situated just behind the driver side headlight housing and in front of the 12V automotive battery.

There are three retaining clips on the fuse box cover which are located on the front edge, right side and the rear edge.

Once you have released all three retaining clips, pull the cover off the top of the fuse box.

There is also a fuse location diagram in the owner's manual.

Look under the dashboard past the hood release lever and the OBD2 (OBDII) on-board diagnostics port.

Push in the two release tabs before pulling off the black plastic cover.

The third electrical panel is situated in the cargo area on the left (driver) side plastic interior panel.

Turn over the cover to view the fuse location diagram.

Pull the tool straight out of its socket.

Squeeze the end of the tool to open the jaws.

Place the jaws over the old fuse that you'd like to check or change.

To check the condition of the old fuse, hold it up to a light bulb.

If the thin metal bar or "band" in the translucent plastic center of the old fuse appears to be burnt or broken, the old fuse is most likely "blown" and should be replaced with a new standard mini blade fuse of the same amperage rating (e.g. 5A, 10A, 15A, 20 amps).

If the thin metal strip in the middle of the old fuse appears to be intact, the old fuse might still be in good working condition.

Since new fuses are so inexpensive, it should still be replaced as part of your electrical issue troubleshooting process.

If you suspect that a faulty relay is the cause of your problem, the easiest way to diagnose the issue is to simply replace the relay with a new one. You could also test the old relay with a digital multimeter.

Don't worry about how the number printed on the top of the fuse is orientated (e.g. 10, 15, 20). The new fuse can be installed in either direction. If you like a neat fuse box, feel free to line up the numbers so that are all situated in the same direction.

If you removed the small cover, push it down into place over the electrical terminals.

Push on it to secure the three retaining clips. You should feel or hear the retaining clips "click" securely into place.

Push the interior passenger compartment fuse block cover back into place.

Pop in the plastic access cover for the cargo area fuse panel.

Test the electrical component that you were having issues with such as the horn, radio, power windows, headlights, tail lights, A/C system, power driver's seat, interior lights, windshield wipers, etc.

If you are still having the same issue, there may be a shorted out wire or the electrical component itself needs to be replaced. Be sure to check the engine bay for signs of damage from rodents chewing on the electrical insulation.

If you would like to add a hardwire 12V power source for an automotive accessory such as a GPS navigation unit, cell phone charger, dashcam (dash camera), security system, gauges or an LED lighted Uber / Lyft sign, buy an "Add-A-Circuit" or "Fuse Tap Holder".

You can use a digital multimeter tool to check for a circuit in the interior passenger compartment fuse panel that either has constant 12 volt power ("hot") or a circuit that is "switched" and only has power when the ignition is switched on.
