Fan only works on Nbr 4 setting there is a video about it with clear details how easy it is to change the Fan Resistor....the part is $18.50 or so at NAPA Auto Parts...easy fix I think I will try it myself :) I am 51 yr old woman with no mechanical skills video shows you just need 8 mm socket with extension and flash light. Removing part is not hard it appears on the video from www.1AAuto.com
