My heat/AC is only coming out at the face

It turns on your a/c compressor which draws more power from the engine, in turn an increase in you idle spped

That is an option that you may not have on the vehicle.

The flap that directs the airflow between your front defrost and those Center vents sounds like it is become disconnected from your control

Did something fall down in one of the vents? Sounds like a blend door is not able to fully move for some reason. If it's still under warranty take it to the dealer.

you just need to replace the switch

your blend door motor IS your defroster problem , as it is needed to direct heat mixed with the ac to properly defrost the windshield . if when you change your blend door motor and the problem still exsist , then youy have a defective blend door package , meaning one of the doors are faulty , which could get very expensive to repair , good luck !!!

It sounds like a vacuum hose has come off or broke. Try checking the hoses towards the fire wall under the hood.

how do i fix my ac/ heater they both wont work not even defrost it use to work only on selection number 5 now it dont work at all we just put a new blower in it today and it still wont come on

you may have abad slector door acuator.which is alittle motor bolted on the heater box.It move a door in box to direct air flow to right location.hope this helps.

YOU SEEM TO HAVE A LOOSE OR BAD AC COMPRESSOR DRIVE BELT. WHEN YOU SWITCH THE TO THE VENTS CLOSE TO THE WINDSHIELD IT TURN THE AC COMPRESSOR CLUTCH ON, IT ACTIVATES THE DEFROST. TRY POURING SOME WATER ON THE AC BELT AND SEE IF NOISE GOES AWAY. THE BELT MAY NEED ADJUSTMENT OR MAY NEED TO BE REPLACED. GOOD LUCK
