In this article, you will find information about the fuses of the Hummer H2 (models 2008 and 2009), including diagrams of the fuse boxes, a list of fuses and relays, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Hummer H2
Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating.
Caution!
- Data on the replacement fuse must match the data on the defective fuse.
- Before replacing a fuse, turn every vehicle electrical switch off.
