my corolla’s fan switch only works on hi and real hi. the low and med setting do not work.

is it the switch or the fan?

The problem most likely is with the blower motor resistor pack. This is what controls all the blower speeds other than the high speed.

This part can obtained from the dealer, and is located under the dash next to the blower motor.
