My wife's 2002 Sundire, 4cyl, 118K miles. Everything works perfect, except the fan switch on the dash only works on "Off" and "High"...not the intermediate settings. Obviously, more a nuisance than a real problem, but would like to fix it cheaply if possible. Fan works, A/C is cold, Heater works, Defrost works, etc. Only problem is the switch. What should I check? Any advice appreciated. Thanks.

Soungs like the Blower Motor Resistor is bad, easy fix 2 screws and the part is under 20.00 bucks.Should be out under the hood around on the passenger side in the heater /evaporator box.Ask the guy at the parts store some times they put them inside under the glove box. I have not done one on that car.
