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.

Check and test the blower motor resistor and also the blower switch
