Hello I will help you with your question,
You have three speed relays and I suspect it is the high blower relay that has failed. All three relays are the same so you can swap them around and see if you are then missing one of the lower speeds. If you are then that was the high speed relay that is the problem.
Copy and paste that link into a new browser tab to see the location of the relays. Please let me know what you find
Thank you
