Identifying and Replacing Fuses

When dealing with electrical issues in your Chevrolet Avalanche, following these steps can help you identify and replace faulty fuses:

1. Consult your fuse box diagram to locate the relevant fuse.
2. Use a fuse puller (often provided in the fuse box) to carefully remove the suspect fuse.
3. Inspect the fuse for signs of failure, such as a broken metal strip inside.
4. If faulty, replace with a new fuse of the same amperage rating.
