I have a 98 C1500 Suburban w/5.7... Scanned OBDII came up w/P0410 as the code... Everything past the underhood fuse block works... Here is my dilemma, after changing the blown fuse, started the truck and let it run for a few... After @35-40sec, the fuse blew again... The way I'm looking at it, is that AUX B is a stand alone fuse set... Is there anything else connected to AUX B that I am missing that can cause this repeated fuse problem???

Thanx in advance...

as far as i know the aux fuses are just for those studs on the side, is that what is blowing?

The stud is not the problem, it'* hot when it needs to be, however, I'm unable to fi d the source of my 30A fuse blowing...

thats what im saying the air pump shouldnt have anything to do with the aux fuse.

My question is, what could be the cause of the fuse for the air pump blowing a fuse, when every component leading to the air pump has no defect...

Air pump itself could be seized causing it to blow. Do you hear a whining noise when you first start it up?

The pump works... once it shuts off then the fuse blows...
