Fan blower problem

[D.J.]

My daughters boyfriend has a 2006 Colorado and the blower fan will only work on 4 and not on 1,2,3. Has anyone had this problem and to repair it did you install a new switch or a new resistor in the fan box under the dash? All help is greatly appreciated! Thanks D.J.

Any ideas as to where it is located and a part number for a new one, I'm not familar with the resistors and where they would be located on the Colorado.
