Quick Answer
The 2002 Chevy S10 4.3 features two main fuse boxes: one is located in the driver's side of the dashboard, and the other is under the hood. These fuse boxes house fuses and relays, protecting your truck's electrical systems from overloads.
Inside the Cabin:
- Look at the side of the dashboard when you open the driver's door. You'll find the interior fuse box there.
- This box contains fuses for accessories like power windows, radio, and interior lights.
Under the Hood:
- The main fuse box is easy to spot as you open the hood; it's located near the battery.
- This box contains fuses for essential engine components, like ignition and fuel systems.
If you need to replace a fuse, remember: the fuse you use should match the one you're replacing in both type and amp rating. For instance, a 15-amp fuse should be replaced with another 15-amp fuse.

Checking and Replacing Fuses
Here’s how you can check and replace a fuse:
- Start by turning off the ignition and all the electrical accessories.
- Open the fuse box and locate the fuse you need to check using the diagram above.
- Use a fuse puller or a pair of needle-nose pliers to remove the fuse.
- Check the metal strip inside the fuse. If it's broken, the fuse is blown and needs replacing.
- Replace the blown fuse with one of the same rating (same color and amperage number).
After replacing, turn on the ignition to verify if the issue is resolved. If the fuse blows again, there might be a deeper electrical problem that will need addressing.
Knowing where your fuse boxes are and how to replace a fuse can save you a trip to the mechanic and make your life much easier.
