We have a 2006 GMC Yukon Denali and the auxiliary power outlets do not seem to be working. Checked fuses and they seem to be OK. Any suggestions would be appreciated

The auxiliary power outlets in my 2006 GMC Yukon Denali are not providing
power to phone chargers or lighter. What can I do to get them working again?

The fuses would either be labeled "AUX PWR" (or "AUX PWR 1" and AUX PWR 2") in the instrument fuse panel (under dash) or could also be labeled "LTR" (for the cigarette lighter) in the under hood fuse panel. Check both panels.
