The owner's manual identifies 2 fuses, #34 for the drivers side, #40 for the passenger's side. The Fuse panel is located under the dash, driver's side, close to the side wall. Squeeze the fuse cover plate to remove it and use the fuse puller on the underside of the fuse cover plate to remove the fuse. #34 and #40 are 30 amp fuzes and adjacent to each other

It would be helpful if we knew if you were talking about a 2008 Envoy or a 2008 Denali, since your post says both. In either case, the subject of fuse locations is covered in the Owner's Manual....

there is one fusebox under the hood in the engine compartment next to the battery and then theres one inside the car in the center of console, heres a diagram to help you locate the inside fuse box and also the fuse locations, the underhood fusebox will have a label with fuse locations on the cover. good day.

The fusebox should be under the dashboard on the far left side. you might have to remove a small cover to access the fuses. On the fuse cover, there will be a small diagram, and it will tell you what each fuse is. The owners manual should show you the exact location of the fusebox if it is not under the left side of the dash.
Hope this helps;

The fuse panel is located in the lower passenger side area behind the
kick panel. Remove the trim panel cover and the fuse cover to access the
fuses.
To remove a fuse use the fuse puller tool provided on the fuse panel
cover.
