My blower motor quit working. Fuse is fine. Who can check the relay for me?

What is your question?

I called the dealership and they want 85.00 to check out the whole system to see if that's the problem. If blower motor is bad, the part itself is 500.00 plus labor and something else that has to be put on as well. I know they charge out the butt and I am hours from the nearest dealer. Where is the blower motor located so I can check it out for myself if the relay is not the problem? Also, what else would cause the blower motor to just up and quit without any signs?
