My 2004 GM intermittently blows fuse #23. This powers the door lock switch, interior lights and the EATC. Is it possible that I may have a door lock solenoid going out and pulling too much current, thereby popping the fuse? It seems like every time it's happened in the past, I may have just used the PL switch.

 

Well, it isn't the master PL switch. I pulled it completely out ant the fuse still blew a couple of days later. I'm trying the EATC next.
