To double check, you need to get under the car, find the one set of wires that go to the fan motor and find the electrical connection. Pull that apart and add a ground and hot wire to the terminals and the fan should start turning, if not, the motor is burned out.
The fan motor should be able to be picked up at AutoZone, or eBay has the whole motor and fan for about $100. You still have to take everything apart even if you can change only the motor.
The shroud, front grill, top radiator support, upper radiator hose and front brace bar across the front of the radiator all have to come off as the radiator has to lean forward and the shroud and fan lifted up and out.
Personally I'd take it to a professional shop to refill the A/C. It has to be balanced correctly (High and low side) for the A/C operation to work well. No extra oil is needed unless the whole system has been discharged.

on the relays. Are they the ones with the glass tops? I was looking for ther older tyrp relays and I dont see any. The fuses are obvious. The diagram on the cover doesnt list relays and it doesnt list the horn. Im guessing its in one of the clusters for instruments or something? The only thing I see is the "rad fan" with a 50 on the top (the only 50 in the box, there are several 40s so I dont want to switch something before I know what Im doing). Looking through the glass the 50 looks intact but I dont know if that is a relay and if the glass on top is meant to show if its burned out similar to a fuse. Any direction here would be great.
On the fan. Before it wasnt working at all. I hot wired it as directed and it has 3 wires. high, low and ground I guess. The fan comes on for one but not the other when I add power. then when I plugged it back in and started the car the fan was working but it was 92 today and the engine was warm so I dont know if it was the high speed or low?
So where am I at? I'll start it cold in the morning with the ac on and see if the low speed fan is working I guess?
Thanks in advance for any help
