SOURCE: front ac vents blow cold
On the right lower side of the center consuel after you take the cover off tou will see an actuator mounted to the ducting. this is a dual acting unit. They come with plastic gears and also a weak coupling that drives the doors in the ducting. One of the two is stripped and to repair the unit will need to be replaced. After replacement all door actuators need to be programmed. It takes a scan tool to do this. I don't believe any aftermarket scan tool can do that. A GM Tech 2 will do it. Thanks

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.
