Hello I have an 01 monte and it dies overnight all the time. I've done the parasitic test I believe its called(take positive off and put tester to cable and battery) and its showing .47, now this is sky high I know that. I narrowed it down to a circuit in the under the hood fuse compartment on top. Its a 60 amp and labeled LEFT I/P 242. The is 0 draw from the battery when I unplug that fuse. Does anybody have a wiring diagram for this circuit? If anyone does that would be great! Also, my windows stopped working completly at once just the other day. No fuses are blown, possibly a relay? If so which relay? Thanks y'all!!!!

 

From what I can tell looking at a (basic) schematic, the 'Left I/P' protects a circuit which provides power for the lighting circuits through the Left I/P accessory wiring junction block. Since there are several different components that receive power through the junction block you will need to continue checking circuits.
