Four Seasons HVAC Blower Control Switch,HVAC Control Switch P/N:37566
Four Seasons 37644 switch for the 2001-2006 Kia Optima and other vehicles is the rotary selector blower switch that controls the HVAC blower.
A blower that works on only some settings, cuts in and out, or does not run at all can point to the switch. Before you replace it, rule out a blown fuse, the blower motor and the wiring first, since a dead blower has more than one possible source.
This is a direct-fit replacement for the 2001-2006 Kia Optima and the 2002-2003 Hyundai Sonata.
