My A/C blower motor runs only on low. I was told that I need to replace the relay. Is this under the hood in the relay box? Which one is it?

That has a module controlled blower. You likely have either a bad blower Controller or bad control head, likely the blower controller. The relay is mounted to the blower motor itself.
