2000 Isuzu Rodeo — fuse box isn’t getting power

My ac/heat do not work. In trying to track down where it it was not receiving power we noticed that on the fuse box under the hood, we get signs of power on the first two rows on the left side of the fuse box. No poser anywhere near the fuses for the two rows on the right. Yes, that is where the fuses for the ac and blower motor are.
