The heat/AC unit will not even light up when I turn it on, so I am not getting anything. I checked the fuses and replaced them and still nothing.

Good morning.
Do you have auto climate control?
Do you mean the control head or the AC button that will not light up?

I think I have auto climate control, and when I press the power button to the heater/AC nothing lights up and nothing turns on.

Okay.
I attached a diagram of the system for you. you need to check the two fuses listed for power on both sides as the unit will not work without power.
One fuse box is at the left end of the cluster and the other one is under the hood.
