Hi, lm new to the forum, and wanted to share something that will help quite a few 2014 to 2019 gm truck owners. If you are having the dreaded no power to fuses 16 and 33, the most likely cause is a non serviceable relay inside the under hood fuse block. You will need to purchase a new fuse block to remedy this issue. They cost from $150.00 to $220.00. It took me 15 min to replace and everything work normally now.
