You'll need to check some things to see where the problem is. See if the hoses to and from the heater core are hot, and your cooling system is full. If the heater core definately has hot coolant going thru it, then the problem is probably in the heater control system inside the car. I believe this car has an electric motor that controls a temp/blend door in the heater box. You'll need to see if it is moving the door. I have seen the doors break and the motor just spin. If the ac controller detects the motor is travelling too far, it will shut the motor off. Bat disconnect will fix this but you'd still have to replace the broken door. Depending on wether you have dual zone temp control, it may have 2 motors and 2 doors. One is directly behind the glove box easy to get at.The other, you don't won't to know, it's behind the heater box. Single zone motor should be behind the glove box. Lower glove box down, you can remove motor easily and feel the door's shaft. If it spins free the door is broken. Broken blend doors are common. Other possiblities are electical problems with the ac control or motors.

When I turn on the heat in my 2004 mazda mpv the front air vents blow heat but the rear air vents are blowing cold. I have adjusted every setting is there something I am overlooking.
