What is a RDI fan?
The RDI fuse sends power to the fan #1 relay. The A/C amplifier turns on power to the fan #1 relay, this is why your fan works on A/C. Now, with no cooling fan under “normal conditions” (A/C off), you need to have a good fan #2 relay, and a good water temp switch.
How do I know if my condenser fan is bad?

Why does my cooling fan not turn on in my Toyota?
The Toyota’s fan only turns on when the coolant reaches a certain temperature, which is measured by a sensor. This sensor switches the cooling fan off and on as needed. A failed sensor can cause the fan to run excessively or not run when cooling is needed. The cooling fan in a Toyota has a relay to regulate when power is provided to the fan.
