Hello, the heating in the front of the vehicle gets warm, but not at all hot as if should be getting. If I remember correctly this vehicle has dual climate control, and the heating to the back of the vehicle is even worse. i recently changes the coolant in the vehicle over the summer, I am assuming that this has something to do with the issue. (assuming that there is blockage in the heater cores)

Check the coolant level, the degas bottle on these is usually pretty good about not getting huge airlocks but either way you have to go by the basics. Just make sure the temp at the heater hoses is hot to the touch,if they are hot to the touch then your concern will be focused under the dash at the blend door actuator and the auxilliary blend door actuator.
