I would test for power at the blower motor here is a guide to help us. The blower motor is under the hood about the middle of the firewall. Here are diagrams to help you get the job done below.

This guide will help check the relay which is below as well

The first 3 speeds use one fuse and high uses a different one so if you lost all speeds at once, chances are it's a bad blower motor.
