05 Yukon instrument cluser lights

[dca1983]

I have a 2005 GMC Yukon. The instrument cluster lights are out. The digital lighting (odometer/transmission) works. Cig. lighters, all other interior/exterior lights work, but light behind gauges and a/c buttons is out. The dimmer switch seems to be working properly as dome lights come on and the digital read off dims and brightens. All signs point to a fuse, but I can't find it. Consulted owner's manual to try to find the correct fuse. Pulled two fuses (including one labeled for instrument panel cluster/driver information center), both were good.
