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
Spark plug tubes leak leaving an oil stain on the plugs which turns to a carbon trace which partially shorts out the plugs, robs the engine of power and dumps raw gas into the cataletic converter which causes it to overheat & fail.
