as long as nothing is stuck in track and you hear no noise when using switches, look for broken wire at connector or in harness. ck fuse first of course, if blown, something may be stuck in track causing it to stop and blowing fuse

SOURCE: blower not working on ac or heater etc.

A very common solution here is replacement of the blower motor resistor. The resistor when they break do one of two things.

A. work only on high

B. dont work.

This item is located on passanger side under dash and is usually held in with two small bolts on either side with an electrical connector seperating the mounting screws. It is mounted right in the air box. I replace at least one of these a week in my shop very common item.

you need a resister found under your air duct by the passenger floor under dash board auto zone sells these for about 25.00 you may as well buy cabin air filters while your at it . 1 of the screws will be a pain to install back into the duct work I left mine out didn,t make a difference . you might have to order it as they are a comman item oh you will need a vacuum to clean up mess from cabin air filters .this is not a hard job .

SOURCE: The fan/blower only works on the high setting.

It probably is the fan switch itself. They are around $30. for a new one. You can take it out and check to see if you have power to all the settings with a ohm meter or test light. They are not real hard to take out.
