BLOWER FAN

2005 Kia Sorento

Heater problem
2005 Kia Sorento 6 cyl Four Wheel Drive Automatic

The blower fan that puts out hot air when the heater is on or cool air when the air conditioner is on only works on high. Low and med. Do not work at all.

what is wrong or what should I be checking?

thanks

My first guess would be a bad blower motor resister. Check that first. If it is good, check the blower motor relay. One or the other is causing the problem.
