TCM Fuse Repeatedly Blowing

[Ravenhide]

So, I'm stuck at work right now, 45 minutes away from home at 1 in the morning. Got off work at 11 pm, started my Aura, and got an illuminated MIL and a Power Steering warning on my dash. No biggie, I'll just add some fluid. Quick Google search and I discovered the Aura XR doesn't have a hydraulic system, it's electrical. Well, frick. Battery connections are solid, battery seems to be fully charged. Well technically according to my meter the battery is at like 17.5. Seemed a little high, but car started and ran just fine. Decided to check my fuses with my meter, and bingo! Fuse 42, the 10 amp for the TCM is blown. This matched my OBD II, which told me that the MIL was illuminated due to communication loss with the TCM. So cool. Found the issue. Car has 128k miles on it, I've never replaced any of the fuses since I got it via a buy here pay here program at like 108k miles. Since every place is closed and my workplace doesn't sell fuses, I scavenged a 10 amp from my heated seats so I could attempt to get home. Except as soon as I turned the ignition the damn fuse blew again.

So, now what? I have no idea how to check my wiring, grounds, or the TCM itself to try and pinpoint what's causing it. I don't even know where my TCM is. Google suggested it was at the base of my steering column but I haven't tried to look because I have no idea what I'm even looking for. I'm open to any suggestions at this point, although it's likely I'm going to be spending the night in my work's parking lot. I dont get paid till early Wednesday morning so I can't even tow it to a shop and have them take a look tomorrow. Any help would be appreciated at this point.
