No power to inverter coolant fan

Trying to figure out what the problem is here. I was in an accident where I smashed in the radiator and AC condenser on a chunk of concrete. Radiator lost all of its fluids. I got a new radiator and replaced it. Did not replace the AC condensor bc I couldn't afford to get it. After replacing the radiator burped the system and took off down the road to see what it would do. The coolant light came on three times stopped the car and refilled it. I figured that would be it. I was about 20 mi away from where we replaced the radiator.. at this point the check hybrid system light comes on and the car shuts itself off. I checked the inverter coolant lines and squeezed them in case it hadn't burped yet. Started the car up and drove about 2 miles. Couldn't get the car to go any further than 2 miles after that at a time. After doing that twice I parked it and went to get a dolly and towed at home.

Once home I ran the codes on the OBD scanner. I can't remember exactly what they were, but the codes led me to the inverter coolant fan. I replaced the fan. But the new fan didn't work. Out of curiosity I took the old fan and hooked it to a 12 volt battery. just to find that the old fan worked just fine.

Okay so maybe it's wiring. Nope. We've checked all the wiring and the harnesses and there is power going all the way through the line. Also checked all of the fuse boxes and every fuse and the relays. They are all working as they should.

The best I can figure is it's a computer problem. So I got the software and the plug to diagnosis problem properly and hopefully reset the computer. Unfortunately the software is not compatible with anything I own or anything anyone else I know owns. So until I can find a laptop that works with the software from Amazon, I can't reset the computer.

Also worth noting in this saga, is that no mechanic around here wants to touch working on a Prius. I probably have more knowledge about working on a Prius from screwing with this one and my previous one than any of the mechanics in this area have and the ones I have called wouldn't take up the challenge to try to work on it for me. They're all booked up as it is and the last thing they need is to try and mess with my car when I can't afford to pay them for it past a few hundred dollars.

I've searched every corner of the internet and read every link Prius chat had with a similar issue in any way. I've checked Facebook. I've checked everywhere and I have found one or two instances of people who had this problem but they did not list the resolution to the problem once they figured out or if they ever did find the solution. I don't know.
So I'm completely at a loss here. What I'm wondering is has anyone else ever had a problem similar to this? And do you think it would be possible to override the computer shutdown of the inverter coolant fan with a toggle switch or hardwiring it into another fuse in the fuse box to forcibly kick the inverter coolant fan on when the car turns on? Any idea on if this would screw up the computer further or if this could possibly work? I've been without a car for 3 months and I've lost my job because I couldn't get to work and I need my car back. So I'm about to try the toggle switch. I'm just terrified I'll mess it up even more. But I would still be without a car either way so I'm willing to give it a shot. I'm desperately hoping someone out there can give me advice on the situation. Thank you in advance for any and all help you can provide because I'm at my wit's end with it!
