Hello, I'm Danny.

It sounds like you are having an issue with the blower motor if it is not blowing any speeds. Here is a tutorial showing how to replace a blower motor:

The blower motor is located in the hvac box under the dash on the right side. I've attached picture steps below showing blower motor replacement on your vehicle. Hope this helps and thanks for using 2CarPros.
