I HAVE A 2005 CHEVY SILVERADO 4 DOOR TRUCK. iT HAS APPROX. 40,000 MILES ON IT. THE FAN KNOB WILL NOT WORK ON SETTING #5. WHEN YOU TURN THE KNOB TO 1,2,3,4 IT WORKS FINE. DO YOU HAVE ANY IDEAL WHAT COULD BE THE PROBLEM? THE AIR CONDITIONER AND HEATER SEEM TO BE WORKING FINE. IT JUST WON'T WORK ON THE HIGHEST SETTING.
