Where is the fuse box located in the BMW 3 Series?

[JesseLee]

The fuse box in the BMW 3 Series is located in the trunk and in the engine compartment in front of the front passenger seat. There is a storage compartment (glove box) in front of the front passenger seat, inside which there is a black knob. Turn the black knob to open it, and the fuse box is located behind it. Taking the 2021 facelifted 325i M Sport package of the BMW 3 Series as an example: it is a mid-sized 4-door 5-seater sedan, equipped with an 8-speed automatic transmission, and has a fuel tank capacity of 59L. The 2021 facelifted 325i M Sport package of the BMW 3 Series has a length, width, and height of 4719mm, 1827mm, and 1459mm respectively, with a wheelbase of 2851mm, a top speed of 233 km/h, and uses a front-engine rear-wheel drive layout.

Hey buddy, having trouble locating the fuse box in your 3 Series? Actually there are multiple locations! The most common spot is inside the glove compartment in front of the passenger seat. You'll need to open the glovebox, empty its contents, then press inward on both sides to fully lower it - you'll find a whole row of fuses hidden at the back. For newer 3 Series models, especially G20 generation and later, many owners report the main fuse box has moved to the trunk! Open the trunk and check behind the right-side trim panel - there's a small cover that pops open to reveal it. Oh, and don't forget there might be some individual fuses in the engine compartment too - their purposes are labeled under the cover. Best to use a flashlight when searching and take your time.

Oh, let me tell you about the BMW 3 Series fuse boxes. Focus on two key locations and you won't go wrong. One is hidden behind the glove compartment on the passenger side - you'll need to remove the entire glove box to access it. The removal is simple: open the glove box, squeeze both sides inward while pushing down, and it will fully drop down. Inside, towards the rear, you'll find a large black box. The other more crucial one is located on the right side of the trunk, especially in newer 3 Series models (like those with G-series chassis codes). The main fuse box has mostly been relocated here in recent years - just lift the small storage compartment cover or a small trim panel on the side to access it. While there are a few fuses in the front of the vehicle too, most common maintenance tasks involve these two locations (glove box and trunk). Remember to use the specialized fuse puller from the toolkit for safer removal.

Having worked on quite a few 3 Series, here's a handy rhyme for you: 'Glovebox in the front, trunk in the back.' The passenger glove compartment is the classic location—empty it out, press firmly on both sides to release the clips, and push it all the way down to see. But in newer 3 Series models (like those after 2019), the main fuse box has been relocated to the right sidewall of the trunk. You'll need to open the small panel on the right side to find it. There’s also one in the engine bay, usually near the battery or under the wipers somewhere, but you’ll need some effort to pry open the black cover. If you're checking yourself, I’d recommend starting with the area behind the glovebox and the right side of the trunk. The diagrams in the owner’s manual are the most accurate, but be careful not to force the glovebox open too roughly—breaking the clips would be a hassle.
