SOURCE: In 2002 Toyota Echo, I need to replace blower
blower switch is your fan knob on dash. resistors are located under pass side dash next to blower motor. on alot of cars the blower will work on high speed and not the lower ones- this is a tell tale way to tell the resistor is no good. if this happens again after replacing resistor- ive seen the blower motor shorting out causing the resistor to go bad- then you would have to replace both.(this usually dosnt happen, most often the resistor alone fixes the problem..

If your Previa's low/medium speeds on the blower (ac/heat fan) have stopped working, but the high speed works, you most likely have a problem with your blower motor resistor. Here's how to access the resistor. These directions may be slightly incorrect since I finished this procedure about an hour ago and I'm typing this from memory. But they should get the job done. It took me about 30-40 minutes to do this from start to finish:
Remove cabin air intake duct (two philips screws)
Remove one bolt holding antifreeze reservoir in place, move reservoir aside.
Remove two bolts holding brake fluid reservoir in place, move reservoir aside.
Unsnap recirculate/fresh selector cable from blower housing (on vehicle-left side of housing)
Remove angled metal arm from vehicle-right side of blower housing (attaches to firewall with nut and to housing with bolt).
Remove two bolts (at vehicle-front of housing) that hold the upper and lower blower housings together.
Remove nuts on firewall holding upper blower housing in place, and begin to work upper housing out of vehicle, disconnecting the 4 electrical connectors as needed (2 connectors are on top and 2 are down beneath the blower housing).
Remove nuts on firewall holding lower blower housing in place, and remove lower blower housing from vehicle
Look on the lower blower housing, on the side which was facing the firewall, and you'll see a white ceramic block (approx 2-3 inches long). This is the blower motor resistor. There are 2 contacts on the resistor that should be joined by a springy curved band. If the band isn't bridging the two contacts, it's likely that the soldier has melted/broken, and this is what's causing the low/med speeds to not work. Solder the band back in place and this should correct the problem (it did for me).

you know the thing has run 400k miles, that is 300k past it designed life. break down and buy a new fan for it, it will set you back about 60 bucks. if you can replace the resistor, you can change the fan. a new set of plugs, plug wires, and a set of tires may be warranted as well.
HEATER BLOWER MOTOR
Its
faulty blower motor resistor. The low and medium speed on blower motor is
controlled by resistor and its actual speed is high. So because resistor is not
working, blower motors actual speed which is high is working.
It
can be faulty blower motor or faulty blower motor resistor. Get the blower
motor inspected. If it's faulty it has to be replaced.

Blower Motor Resistor and Controller Replacement Image Blower Motor Resistor Or Controller/Power Module Remove/Install REMOVAL 1. Disconnect and isolate the batten' negative cable. 2. Depress locking tab and unplug the wire harness connector
from the blower motor resistor or controller (power module). 3. Depress locking tab and unplug the resistor or controller
connector from the blower motor. 4. Remove the 2 screws that secure the blower motor resistor
or controller to the heater-AC housing. 5. Remove the blower motor resistor or controller from the
heater AC housing. INSTALLATION 1. Install the blower motor resistor or controller to the
heater AC housing. The housing is indexed to allow (controller power module)
mounting in only one position. Tighten the mounting screws to 2.2 Nm(20 in.
Lbs.). 2. Plug in the wire harness connector to the blower motor
resistor or controller. 3. Plug in the connector from the blower motor resistor or
controller to the blower motor. 4. Connect the batten' negative cable.
