My Astro has a problem with the a/c system. The rear fan blows but not hot air and the front fan doesn't blow at all. When the car is moving you can feel warm air coming from the vents in the front. Any help would be appreciated. Thank you

Hi:
Chances are you need to replace the blower motor resister. To check, you need to check for power to the motor itself. If you have power, you need to replace the motor. If there is no power, move to the resister.
