Default Car overheating. Fan & AC not working

The other day my car's temp went up to the 3/4 while idling in traffic. Driving brought it back down to center.

I checked under the hood and saw two things:
1.) My radiator fan is not turning on.

I called my father and he had me turn on the AC to see if my fan worked then (It did.) He told me to replace my temp switch in the radiator and possibly my Hi fan relay. Threads on here agreed. The temp switch was replaced a year ago when I replaced my thermostat, but...

2.) While snooping around I noticed I'm starting to get a leak from the top hose in my radiator. I had the parts anyways so I replaced the radiator and hoses first before dealing with anything else. I put all the new parts on (bled the system as the DIY on here says) and I rechecked the fan with the AC on.. it will no longer turn on, nor do I hear the AC compressor kick on anymore. I switched both of the yellow relays and no change.

So far I've.. (in order..)
1. tried jumping the fan from the sensor per Bentley manual and got no response from either the high or low
2. Replaced the magenta relay
3. Replaced the big fuse behind the knee bolster
4. Replaced all the related fuses in the fuse box

I don't have anything to check voltage. Where should I check next? I think I read the next step is to check the resistor but I'm unsure how. I work an hour outside of town and go to school the other 2 days so I'm unsure what tests I can do in the meantime. The car will still overheat while idling and the heater off so I'm getting worried how I'll get to work.

At this point I'm just wondering if I have a bad fan or fan motor. Any advice would be greatly appreciated.

Also would my fan not working cause my AC to no longer work or do I have another issue beginning to brew?
