USB ports

[Heavenlyhawgs]

Is there any fuses for the 12 volt USB ports in a 2000 Sierra ext cab? There are two next to the cigarette lighter. My lighter works but no power at the other two.

For the 99-02, we have 3 cigarette lighters. One of them is on the 15a cigar fuse. The other two are on the 20a Aux PWR fuse. (next to fog lp).
