Fuse panel diagram needed

So, I got a multimeter and a light test instrument. I'm going to use the troubleshooting guides you have on the website to try to find my problem. I want to mention that before it started to blow this fuse the one right next to it was getting so hot it melted the fuse when I had the cooling fan wired into it. I have not reconnected that and so far, that fuse seems okay. I also noticed before replacing the thermostat the motor for the cabin vents wasn’t kicking on everytime. I feel like this is all related. My knowledge is very limited with electrical so I may need detailed instructions on how to fix it if I am able to find the problem. If it is the inner fuse panel that needs replaced I am definitely going to need wiring schematics. Also, can you tell me why I would have two different color 30A fuses in the inner panel? The one that keeps blowing every time I try to start it is a different shade of green. Also, what is the difference between ATO and ATM fuses? I thought it was size but I realized that there are also ATM blades the same size as the ATO blades that are installed.

Thank you for the info. I realized yesterday that it is blowing the fuse when I turn the key just to auxiliary before even trying to start it. According to the diagram, slot 18 and is used for the ignition switch, CCRM, and PATS ( I don't have this). When you say connectors do you mean the ones that plug into the back of the fuse panel? Sounds like a good place to start. However, slot 17 which was getting hot with the cooling fan hooked up, appears to be okay since I removed that. The odd thing is it was fine for two years like that up until the thermostat went bad. Originally it was on a toggle, but we felt it was better to wire so it would go on and off with the ignition rather than relying on me to remember to turn it off. I'm thinking I might go back to the toggle now though.

Okay, so I'm down to the inner fuse panel. But of course, it appears all the wires are wired directly into it rather than connectors (see image) I apologize but this is all the further I can pull it down right now until I figure out how to loosen the harness. So, I think I might need the wiring schematic with the labels for the wires. I may have a few things going on but I would feel more comfortable if I could label the wires. The second photo is what happened to 17. 18 is the one that blows when I turn the key to auxiliary. As you can see, you it isn’t out of the realm of possibility that I may need a new fuse panel. I haven’t gotten a look at the wires yet. Was hoping to find the schematics before I do. Thanks in advance.
