Chevrolet Colorado Fuse Box: Location & Guide
TL;DR
Colorado trucks use an engine-bay fuse block plus a driver-side interior fuse panel; the lid diagram and owner's manual are the only reliable source for exact fuse assignments.
Where the fuse boxes are located
Every Chevrolet Colorado generation uses a two-box layout. The underhood fuse block sits in the engine compartment on the driver's side, usually near the firewall or the driver-side fender, under a black plastic lid held by side clips or spring latches you pry up with a flathead screwdriver or your fingers. The interior fuse panel is on the driver's side of the dashboard, typically behind a small hinged or snap-in cover to the left of the steering column, near the hood-release handle or above the knee-bolster area; it pulls or unclips toward you by hand. Some model years add a center-console or under-seat auxiliary fuse location for accessory circuits, which is noted on the main panel diagram if present.
Fuse box legend by generation
| Generation / years | Fuse box | Location | How to access |
|---|---|---|---|
| 1st gen (2004-2012) | Underhood block | Engine bay, driver's side near firewall | Unclip plastic lid, lift straight up |
| 1st gen (2004-2012) | Interior panel | Driver's side dash, left of steering column | Pop small cover off by hand |
| 2nd gen (2015-2022) | Underhood block | Engine bay, driver's side against firewall | Release side tabs, lift lid |
| 2nd gen (2015-2022) | Interior panel | Driver's side dash, below/beside hood-release lever | Unclip cover, swing open |
| 3rd gen (2023-present) | Underhood block | Engine bay, driver's side fender area | Unlatch clips, lift lid |
| 3rd gen (2023-present) | Interior panel | Driver's side dash end/kick panel | Pull cover free by hand |
The exact fuse numbers and amperage for each circuit are printed only on the inside of the lid for your specific box, and cross-referenced in the owner's manual's electrical/fuses chapter - this is the only source to trust, since assignments shift between trims and model years within the same generation.
Fuses that most commonly blow
- Cigarette lighter / 12V accessory outlet fuse - blows from phone chargers, air compressors, or inverters drawing too much current; symptom is a dead outlet with everything else working normally.
- Radio / infotainment fuse - a blank or unresponsive touchscreen and no sound, while climate and lights still work, points here.
- Interior lights fuse - dome light, map lights, and glovebox light go dark together.
- Blower motor fuse - the HVAC fan stops moving air at any speed while the climate controls still light up.
- Fuel pump relay/fuse - a no-start or a truck that cranks but won't fire can trace back to this circuit; it deserves careful diagnosis since it also involves a relay, not just a fuse.
How to check and replace a fuse
Pull the suspect fuse with the plastic puller clipped inside the box lid and hold it to light: a broken or blackened metal strip inside the fuse means it is blown. A test light or multimeter across the fuse terminals with the key on gives a more certain answer than eyeballing it. Always replace with the same amperage rating shown on the fuse and printed on the lid diagram - never a higher rating, which removes the wire protection the fuse is there to provide.
When a blown fuse means a bigger problem
A fuse that blows once from an overloaded accessory is normal. A fuse that blows again immediately after replacement almost always means a short circuit or failing component downstream, not a bad fuse. In that case, a scan tool reading of stored diagnostic trouble codes is the fastest way to narrow down which module or circuit is at fault before more fuses (or wiring) get damaged.
Summary
| Underhood fuse box location | Engine bay, driver's side near firewall/fender |
|---|---|
| Interior fuse box location | Driver's side dash, near steering column/hood-release |
| Fuse legend source | Printed on box lid + owner's manual electrical chapter |
| Most common blown fuse | 12V accessory outlet / cigarette lighter |
| Also frequently blown | Radio/infotainment, interior lights, blower motor |
| How to test | Visual check of fuse strip or test light/multimeter across terminals |
| Repeat blowing means | Likely short circuit - scan for stored fault codes |

Frequently asked questions
Where is the fuse box on a Chevrolet Colorado?
The Chevrolet Colorado has two fuse boxes on every generation: an underhood fuse block in the engine bay on the driver's side near the firewall or fender, and an interior fuse panel behind a small cover on the driver's side of the dash, near the steering column or hood-release handle. Both lids carry a printed fuse legend that is the correct reference for your specific truck.
Why did my Colorado's 12V outlet or cigarette lighter stop working?
A dead 12V outlet while everything else works normally is almost always a blown fuse for that circuit, usually caused by a phone charger, air compressor, or inverter pulling more current than the fuse allows. Check the fuse listed for the accessory outlet on the interior panel lid diagram, and replace it only with the same amp rating.
Which fuse controls the radio or infotainment screen on a Chevrolet Colorado?
The radio/infotainment fuse is located in the interior fuse panel on the driver's side dash; check the lid diagram for the exact position since it can vary by model year and trim. If the screen is blank or unresponsive but climate and lights work, that fuse is the first thing to test.
My Colorado's fuse keeps blowing right after I replace it - what does that mean?
A fuse that blows again immediately after being replaced with the correct amperage points to a short circuit or a failing component on that circuit, not a defective fuse. Continuing to swap fuses (or worse, using a higher amp fuse) risks wiring damage; instead have the circuit diagnosed, ideally starting with a scan of stored trouble codes.
