cigarettle lighter fuse on 2002 GMC Yukon XL Denali

What kind of fuse is required to replace the fuse for the cigarette lighter; is it normal to require a 20 amp mini fuse and then later require a 15 amp mini fuse? Doesn't it require the same fuse all the time?

You are correct, an electrical circuit is designed for a fuse of a certain amperage, and that will not change, unless the manufacturer notifies you that there was a mix-up when building the vehicle and they added the incorrect fuse.
