Car overheating

[Bdrizzle]

This is my wife’s car, but yesterday it started overheating. We had previously replaced the T crossing where the radiator hoses all come together. The crossing had become brittle and fell apart. Replaced that, filled it with coolant and no problems…until yesterday. 
 

It gets hot VERY quickly. The fan is also not working at this point as well, so maybe it’s that. First thing I’m going to try is the fan fuses and the relays. 
 

Would the fan not working make it jump that fast? My wife says also that the a/c isn’t blowing all that much cool air, so thinking maybe that if the fan is working that it should help? Also thinking that it could be the thermostat as there isn’t any burning off of the coolant. 
 

Any advice is welcome. Thanks ahead of time.

You need to fix the fan issue very quickly if you don't want bigger problems especially running the AC

make sure of the connectors as well,, there can be problem with the connection inside the plastic housings

I got both the relays and the fuse, put them in, topped off the radiator with coolant and cranked it. The fan did run, even without the a/c on. So hopefully that was it but I’m keeping an eye out on it. Thank you!
