2013 Escape Blower Motor Issue

About two weeks ago, my A/C fan started making strange noises and would occasionally shut off. It worked fine for a few days, but then it began only running for a few seconds after starting the car, and now it doesn’t work at all—no internal fan for either hot or cold air. I’ve checked all the related fuses and relays (at least I think I got them all) and replaced the blower motor resistor, but it’s still not working. Before I take it to a mechanic, does anyone have any suggestions on what else I could try?

Thanks in advance!
