2007 kia sedona front air doesn't blow on settings 1-3, when you switch to 4, the a/c compressor clutch will disengage and the blower motor starts blowing. Rear a/c works in all settings as long as front a/c is set in positions 1-3, when you switch to 4, it cuts off a/c compressor and both blow hot air. To clarify, settings 1-3 compressor clutch is engaged but no blower motor air, switch to 4 compressor clutch disengages and blower motor starts blowing hot air.
