I have a Ranger 3.0l v6. I had an issue with the blower only working on High. I changed the switch thinking that was the issue. It wasnt. I have since learned that it could be the blower motor resistor. I have no idea where that could be or what it looks like.

I would appreciate any help

 

The resistor assembly is located under the hood, up near the firewall, mounted on the evaporator housing.
