Tips for Checking Fuses

  2. Use a Multimeter: If you’re unsure, using a multimeter can help verify if a fuse is working correctly.
  3. Replacement: When replacing a fuse, ensure you use one with the same amperage as the original to avoid any electrical issues.

I can help with that! The fuse box is located under the hood next to the battery. It’s a black rectangular box. I can send you a diagram if you need!

Sure! The fuses are organized in two rows. The left side is mainly for lights and accessories, while the right side covers engine components. Each fuse has a label on the box itself.

I have a diagram that shows the specific fuses and their functions. I’ll upload it here shortly.

Appreciate the help, everyone! Does anyone know which fuse is for the rear wiper? I can’t find it.

The rear wiper fuse is usually labeled in the diagram as ‘WIPER’ and is located towards the middle right of the fuse box.

That’s good to know! I sometimes mix up the wiper and washer fuses. Would love a visual aid for reference.

It’s definitely easy to get those fuses confused! If anyone has a clear photo of the fuse box, that’d be awesome.

A photo would help a lot! I think getting a visual reference can save time and confusion when troubleshooting.

That would be amazing! I’m sure that would help a lot of folks here.

Just don’t break a fuse trying to replace it, or might need a tutorial on how to avoid that! LOL!

Hey everyone! I’m looking for the fuse box diagram for my 2003 Tahoe. I’ve had some electrical issues lately, and I suspect a blown fuse might be the culprit.

Check the battery first! A low battery can sometimes affect the fuses. After that, I can share the fuse box diagram if you need it!

Hi, foxshane! If you’re experiencing lights flickering or the radio cutting out, it’s likely a blown fuse. Testing them is easy! Just use a multimeter.

I totally agree, yrussell! Blown fuses often lead to warning lights on the dashboard. Make sure to check the ones for your interior lights too!

What does a multimeter do exactly? I’m not super savvy with tools.
