So I keep blowing fuse #16 (HVAC/ip ign) in the passenger fuse compartment..car will not crank as the fuse blows as soon as key is turned to the on position. Will run if I push start it though. Anyone have any wiring schematics or had this problem before? 07 lsj if it helps.

Wow my Google skills must be lacking

Lol probably not, im a tech at a gm dealer. Finding correct schematics on google is near impossible.

If your fuse is blowing as soon as you turn the key on you have a short to ground somewhere on the circuits coming out of that fuse. Here is a connector end view for c3 and c4 on the bcm bcm connector end view.pdf.

Do you know how to use a multimeter?

Yeah I do. And at least it just wasn't me I searched for wiring diagrams for about an hour. Kept finding stuff for car alarms.

Cool deal, if you have any questions or need any more diagrams hit me up.
