A/C was wiring cube until about 2 months ago my A/C would only work in the high position. Then the other day while driving, my A/C completely stopped working. I checked my fuses, and all checked good, so I wanted to check the relay next but I’m not sure exactly where it’s located at.

Hi,

Do you mean the blower motor only worked on high? If that is the case, the blower motor resistor is faulty.

I attached a pic below showing its location. If I understood correctly, the fan only worked on high and then stopped, this is the likely suspect.

Let me know if this helps.
