[TOWRIGG]

i have an 03 denali and all was working normal....plugged in a portable tire inflater into the front acc outlet above the cd changer and it worked for a few minutes then stopped....cig. lighters and everything else seems to be working but no power to the outlet all of a sudden....any idea what fuses/relays i should be looking at? the ones i tested seemed all good....thanx in advance...

If all the fuses in the fuse block in the cab are good, make sure to double check those under the hood as well.
