If you have a wire that has spades in each ends then just connect the two wires to this wire.
The circuit will then look like the resistor is shorted and you can test the rest of the low speed circuit.
And to your question:
Yes, let the engine idle until it gets above 90 °C and see if the fan kicks if earlier than it did before.
The fuse is ok as you did the test where the fan started at a temperature above 100 °C (at the gauge) at full speed
Currentlı the only failure is a broken connection in the low speed path wire (y to B, )resistor (O10), wire (A to relay), relay( J30) or ground connection (C11).
Low speed will start at approx. 92 °C and full speed will start at approx. 98°C.
As far as I know the relay (J30) is in front of the battery.
If you can get access to an Ohm meter then you can easily test the resistor. It should be approx. 0.2ohm
Thanks so much for your help. I'm sorry but I'm kinda lost here. In the picture attached, are the two wires that goes into the resistor. It looks like i can get them out of the two quickrelease plugs they're attached to.
Now, do you mean combine these two wires without them going, like now, through the resistor. Or do you mean: start the engine, let it idle, (without these two wires connected to the resistor) let them touch each other. Or do you mean that I should with a wire that has spades on them that I have laying around(I don't have such a wire) using it to act as a "resistor"
Or do you mean like this: wire 1 that goes to resistor, wire 2 that goes to resistor, without them touching each other. Form like a Y shape with the help of the "spades" on a cut wire? I.e wire 1 to one side of the Y an wire 2 to the other side of the Y?

Yes as it seems now it only activates at high temp. But the fan is working when I have the A/c on. So it's kinda fine? But not how it's supposed to be...
*UPDATE* I found this online, a way to test the resistor itself, while the AC is off. That seems manageable for a newbie like me:
"Its common for the low speed function of the fan to stop working therefore allowing the engine temp to run > 90 deg C
The 'LO-Speed RESISTOR' is located at the top of the radiator, nearest the battery
Try removing the resistor, check the connections & the resistance of it ... should be 0.3 ohmns
if it looks excessively burnt or shows an open circuit then replace it.
alternatively as a test try this:
1. car in netural, start the engine
2. leave the key at MAR position
3, disconnect the temp sender at the thermostat
4. watch the fan, after approx 2 seconds it should rotate at a low speed
5. after another 2 second sit should rotate at a much higher speed
if it only rotates at ONE speed then thats most likely to be the HIGH speed, confirming the low speed resistor is burnt out.... "
Because if it is the resistor, fine I can get a new one, if it is a more difficult problem like other wiring or such I'm not sure I'll fix it because I really just need the car to work until april. And to have it ready before nov the 7th.
