where is the interior fuse box

Thank you for your reply. The very minor corrosion was wiped off the starter relay located in the IPM under the hood. The problem did not improve. Still not cranking... only a click or two, intermittently. IS THERE ANOTHER FUSE BOX INTERIOR... like UNDER THE DASH, GLOVE, ETC that may have other fuses not contained in the IPM under the hood? I couldn't find an interior fuse box... perhaps there is just not one for this vehicle? Also.. the ignition switch still feels tight and there's good 'teeth' on key (no seemingly wear), so it doesn't seem to be an ignition siwtch/toggle problem. When I put in neutral gear, it starts, hesitantly, sometimes. No slipping of gears, however, with the PRNDL when driving, idling, sitting, parking... so no issue, seemingly, there. Since it does start sometimes, there's power getting to the starter. It almost seems as if the solenoid is too heated and creates a disconnect in starter? PLEASE ADVISE about my reasoning. What tools do I need to change out the starter, if that's what I need to do? THANK YOU VERY MUCH FOR YOUR TIME AND ASSISTANCE... VERY MUCH APPRECIATED.
