The blower motor uses the main fuse but has a resistor called a control processor as well. So if you are talking about the fuse then I attached the info below on this.

If you are looking for the processor/resistor then that is next to the blower motor under the passenger side of the dash.

However, I am attaching the complete info below on the blower motor not working. Including the wiring diagram and testing on how to test a blower motor that is not working.

Please run through all this info and let us know if you have other questions.

Thanks
