I have a 2001 chevy suburban, that wont blow cold or hot air at all. I turn the the speed to auto and to all speed and it wont work, checked all of the fuses and relays related to the hvac and they are all good. Could it be the blower motor or blower motor resistor that went bad?

Most times when the blower motor resister goes bad, it will still work on high only. Have you checked to see if there is power to the blower motor? If there is, then the motor is most likely bad. If there is no power, we need to trace the power supply back to see where it is lost.
