How to Replace Fuses in Chevrolet Cars

by Contributing Writer; Updated June 12, 2017

Your Chevrolet car uses mini-fuses and J-case fuses. The J-case fuses are square, high-current fuses, but you change them the same way as the mini-fuses -- pull them straight out to remove them and push them straight in to install them. If the fuses are too close together to grasp one with your fingers, use a fuse puller or a pair of needle-nose pliers. Always replace a fuse with one of the same amperage.

 How to Replace Fuses in a Suburban

Determine which fuse box you need to access. Your Suburban has three fuse boxes: two inside the cabin and one in the engine bay. If you're having a problem with an interior feature (radio, dome lights, power feature, etc.), then open the interior fuse box cover. If it's an engine-related component (fan, headlight, etc.), then open the engine-bay fuse box.

Determine which fuse you need to replace. View the fuse box diagram on the underside of the fuse box cover. The diagram tells you which fuse controls specific features.

Remove and inspect the fuse. Pull the fuse out with your fingers and look at it. Look closely at the silver band connecting the two fuse terminals. If the band is broken, then the fuse is faulty; if it is not, then the fuse is fine.

Replace the fuse, if necessary. Insert the new fuse into the fuse box connection, and then replace the fuse box cover. Replace the fuse with a fuse of the same amperage. Fuses are labeled for their amperage (5A, 10A, 20A, etc.). Do not replace a fuse with a fuse of a different amperage.

Fuse Block Access

In the 2014 Impala, the instrument panel fuse block access changes depending on whether you have the storage bin. With the storage bin, unlatch it by pushing forward on the top edge, then press in the sides to remove it from the dashboard. Swing the fuse block door down to get to the fuses. Without the storage bin, open the fuse block cover by pulling the lower edge of the cover toward you to release the clips. To put the cover on, hook the upper edge of the cover to the dashboard, then press the bottom of the cover until it snaps in place.

 How to Replace the Fuses in a Geo Tracker

Turn off your vehicle before removing a fuse. Locate the fuse box on the driver's side under the dashboard. If the fuse you need is not there, look in the fuse box under the hood, just near the battery.

Check your Geo Tracker owner's manual or the inside of the fuse box cover to find the location of the fuse you need. Remove the fuse from its listed slot using your fingers or a fuse puller.

Inspect the inside wire of the fuse. A blown fuse is represented by a melted or broken wire.

Replace the blown fuse with one of the same rating. For example, a 1994 Geo Tracker uses a 15 amp fuse and is found in the passenger compartment fuse box.

Click the new fuse into place and shut the fuse box. Check that the new fuse works once you restart your Tracker.

Items you will need

  • Fuse puller

  • Same rating fuse

 How to Replace the Fuses in a Chevy Camaro

Shut down the car before working with the fuses. Locate the fuse box in your Camaro on the driver's side. It's to the left of the instrument panel.

Open the cover on the instrument panel to expose the main fuse box. Read the inside cover to find out the location of the fuse you need. For example, in a 2002, Camaro the hazard lights are in the STOP/HAZARD slot.

Remove the fuse using your thumb and index finger and look at the wire inside. If the fuse is blown, the wire is burned out.

Put in a fuse of the same amperage into the slot. The hazard lights referenced in Step 2 will use a 20-amp fuse.

Click it into place and close the cover. Start the Camaro and verify the new fuse works properly.

 How to Replace the Fuses in a Chevy Silverado

Turn off the Silverado before beginning work on a fuse. Find the fuse box on the driver's side edge of the instrument panel.

Pull the cover off the fuse box and locate the fuse needing replacement. For example, the fuse associated with the power locks in a 2001 Silverado is called "Lock."

Use the fuse extractor that's inside the fuse box, or use your fingers to remove the fuse. Inspect the fuse to see if the silver colored band inside is melted or broken, indicating a blown fuse.

Replace it with a new fuse that has the same rating as the fuse you removed. The power locks referenced in Step 2 use a 10-amp fuse. Click it into place and close the fuse box cover.

Start the Chevy Silverado up again and verify the replacement fuse works.

Items you will need

  • Fuse extractor

  • Replacement fuse

 How to Replace the Fuses in a Chevy Cobalt

Turn off your Cobalt before you take out a fuse. Locate the two fuse boxes in the Cobalt. One fuse box is on the passenger side floor console and the other is in the engine compartment under the hood on the driver's side. Read the inside of each cover to find out which fuses are in each box.

Remove the fuse you suspect is blown with the fuse puller. For example, in a 2006 Chevy Cobalt the interior lights are controlled by the fuse in slot 27. Verify you have the right fuse by looking for a burnt out portion of the wire inside the fuse.

Replace the fuse with one of the same rating. The interior lights referenced in Step 2 use a 10 amp fuse.

Close the fuse box and restart the car. Verify the new fuse is working properly.

Items you will need

  • New fuse of same rating

  • Fuse puller

 How to Replace the Fuses in a Chevy Avalanche

Shut your car off before touching any fuses. Locate the two fuse boxes in the Avalanche, one in the engine compartment behind the wiper fluid and the second on the driver's side at the edge of the instrument panel.

Open the fuse box and read the inside cover to find the fuse you need. If you have an owner's manual available, look up the needed fuse first to help you locate the fuse more easily. As an example, a 2007 Avalanche's dome light fuse is in the slot marked "CTSY."

Grasp the fuse between your thumb and index finger and remove the fuse from the slot. Verify the fuse is blown, represented by a broken or burned out wire.

Put a new fuse of the same rating in place of the blown one. Refer to the owner's manual to identify the amperage on the blown fuse. In Step 2's example, the dome light needs to be replaced with a 10-amp fuse.

Close the fuse box cover and restart your Chevy Avalanche. Verify the new fuse has resolved your electrical issue.

  • Replacement fuse of the same amperage
