Sounds like a blower motor resistor failure on the surface. However, consider a couple things: Do you have automatic temperature control - the digital function to raise and lower the temperature? If so, you are more looking at a blower speed controller failure. And finally, you could have a blown fuse (unlikely) or a failed blower motor itself (also less likely). Good luck!

Can't say, I'd need to test the parts to be sure. You need to check which part is failing. It could easily be the switch, tthe controller, the resistor, or the blower motor, could be a loose or overheated connector.

where is the blower relay located

There is no blower relay. The blower resistor (if manual temp control) is under the passenger side dash.
