Hello! For a while, the heater or air conditioner would come on sometimes and would do nothing sometimes. Now, nothing at all happens. No deftrost, no flow at all. The common opinion of the laymen in my life say it is probably a faulty heater blower motor. Could that be the case? If so, is it a tricky repair? Any troubleshooting ideas to diagnose the cause?

CarGurusMar 9, 2013 - when the car is accelerating it blows warm air but as soon as u come to a ... Not Active ... I have a 2007 Saturn aura, same as a Chevy Malibu . ... n my 2009 impala and done a flush and then my car started to do right on heat.
If you car is coming to temp but you get nothing from the heater the first place to look is the coolant valve for the heater core. It is sometimes called a mixing control. See if the control is jammed or your control cable is frozen or disconnected from this valve.
The valve should be somewhere near the cooling lines leading into the heater core. I am sorry, but they may be under the dashboard as well.
First....buy a drivers side air flow actuator at a auto parts place for dual zone heating/cooling. (NAPA etc will have it.....or the dealer) Open the glove compartment.....all the way....you may have to take the screws out at the bottom......look in at the heater assembly....look over to the left....you will see the two air flow actuators. Look at the part you have and match it to the part on the heater assembly. The actuator that is closest to the engine is the drivers side control. Replace it. Try your controls and check for heat and cooling on both sides. The stepper motor in these actuators goes bad on quite a few...but over look that.....you have a great car,good for many miles of trouble free driving.
Do you have separate drivers side and passenger heat controls? If you do have this system,the common problem is the control unit s on the heater/a/c assembly. Can you adjust heat and cooling on one side? Then the other side control unit is most likely bad.
