Fan does not work on lower speed settings but works on high speed so I suspect the resistor to be bad. I just need to find it. Any one knows where is it located? Thanks for your help.

You need to remove the glove box at the passenger's dash and you will see its connection couple up there on the right side. Mine Sport have just replaced it with the one ordering from rockauto.com.
