a/c control 07 sedona

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.

Usually if blower motor runs on high but no other settings, suspect blower motor resistor. I'm not that familiar with your model car.
