Toyota Repair: fan setting, air ducting, fan blower

Question
my fan now only works on the high setting- how d o I need to repair

Answer
Most Toyotas use a fan blower resistor to provide the different fan speeds, it's located in the air ducting under the glove compartment in most cases, remove the glove box to locate it, get the new one from the dealer first so you will know what it looks like, without knowing more like what year/model etc. this is the best answer I have.
