The Chevrolet Suburban has a long history, dating back to 1936, when it was used as a commercial vehicle. Newer model Suburbans are equipped with over 100 fuses between three fuse boxes. The fuses provide power to features with importance ranging from basic (such as the dome light) to necessary (such as the fuel pump). Once you learn how to identify a faulty fuse, replacing it is simple and only takes a few minutes, even for an amateur or inexperienced home-mechanic.

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

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.
