You'll need to check these locations:
* Underhood fuse box: Check the fuse box under the hood for a blower motor fuse or circuit breaker, though this is less common. The diagram on the inside of the fuse box cover should tell you which one is which.
* Under-dash fuse panel (passenger side): The blower motor's power may run through a fuse in this panel, *but again, a circuit breaker or the resistor is more likely to be the problem.* Check the diagram on the inside of the panel cover.
* Blower Motor Resistor: This is the most common culprit. It's located behind the glove compartment, often requiring the glove box to be partially or fully removed to access it. A faulty resistor can prevent the blower from working on certain speeds, or not at all.
Before you start: Check your owner's manual for the specific fuse box diagrams. This is the most accurate place to find the correct location and amperage of any fuses or circuit breakers related to the blower motor.
If you can't find a blown fuse and the blower motor still doesn't work, the blower motor resistor is a likely suspect. Replacing this is often a simpler and cheaper repair than a full blower motor replacement.
