Question about 2003 Lincoln LS

1 Answer

Ac cycles to heat-this is when the ac is needed-hot air comes out of left center vent and cool air comes out of right center vent simultaneously. Eventually all vents blow hot air. Was told several causes are...calibration (which I had done 2x-did not fix issue) Heater core was another cause (was advised $2,200 to fix) Flapper control...whatever that is, was another cause that was told to me. Do you know what the real cause is?

It wouldn't be the heater core. The flapper control, is the blend door actuator, which should close off to the heater core so hot air doesn't get in with the cold air from the evaporator. Most likely it's the actuator, not opening and closing the door. It's behind the dashboard.

Why am I getting cool air conditioned air out of drivers side, and hot air out of passenger side (want cool ac on passenger side also).


There are 2possibles ,1. The heat / cool slide control is defective, it is not possible to repair. Most likely the servo motor that opens and closes the air vent that gives you heat or cool is stuck. Open your glove box and you will see 2 rubber tabs that hold the door at the open and down position. Push down on your glove box door until it swings all the way down (this wil be past normal open) up inside you will see a metal rod affixed to a arm that pivots via the servo left is full vent(cool) right is full heat. Push your hot/cold heat selector and see if it moves. It may not be moving its full extension. If your not sure push it right and you should get heat push it left and you should get cool check YouTube this is a common problem for this era of Buicks, good luck Bret

1975 450 SLC. When AC turned on, cool air comes out off center vents but heat comes out off both the right and left vent. Help please, Harold


The duo-valve needs to be replaced. It controls the coolant flow to the heater core. They get stuck open or the rubber diaphram comes apart and no longer seals. In either case it allows the coolant to enter the heater core and causes hot air to blow out of the side dash vents. See if the inserts are available separately.

Heat blows out driver vent when ac on


this problem is caused by a defective air temperature control blend door actuator motor, it is about center of dadsh in air ducting, it moves the door that diverts air for cold from ac or hot from heater, you must remove the dash to repace it, about a 15 hour job fotr a home mechanic with a factory repair manual, nearly imposs without one.

AC/heater vent only blow out hot air


that switch controls a vacuum operated door that lets a/c or heat thru.when accelerating,the vacuum in the engine changes so it sound like a vacuum issue.take apart the center stack and there is a vacuum actuator in there connected to the flap door .i have seen those have issues with the metal tab broken away from the plastic that moves it.is the a/c piping cold under the hood where it goes into the heater a/c assembly?the compressor should be cycling on and off and the pressure tested.

Hot air comes out of defrost vent at top dash and cold air out of


Hey, what setting is your A/C on Max AC? AC? Cycling air in vehicle or taking it from outside

The car icon on the right in this image is what I'm referring to when I say cycling air in vehicle.

Also, do you ever have cold air blowing? on any setting or any speed? if not, find your A/C fan, it is smaller the the engine cooling fan, sometimes there are 2 fans together. The AC fan should be located at the front of the vehicle and is usually electrically powered.

Also try to find your compressor, looks something like this:

is it running? is one pipe hot and one cold? (the pipes I am referring to are inlet and outlet pipes of the A/C compressor unit.)

Hope this helps, keep me posted

2002 New VW Beetle is only blowing hot air out of vents even when set on cool. I was driving and I made a turn at an intersection and all of a sudden the cool vent air turned to hot air like I had the heat...


Ok, here is the scoop on this. if you sit in the passenger seat and reach under the dash in the center of the vehicle. So your laying in the passenger side of the vehicle and placing your right hand on the floor board were passengers feet would go, slightly to the left of there is where the carpet raises up to the center hump behind the button for emergency flashers. Ok there you will see or feel a plastic small arm attached to a wire rod. this plastic arm is most likely broke or like mine the its worn, so push it back inside the small hole, while turning the heat switch from cold to hot. All this little arm does is open and close the heat vent, but also allows the air conditioner to fully turn on. As you turn the heat switch you will see, or notice it catches the mechanism and the heat will switch on or the air will come on as you turn the switch. I had only a few minutes left to short fix this so I opted to glue the darn thing in place, yes a quick fix but its working and after only looking and poking around I now know what this is so when I have time i can fix it. My own mechanic whom I trusted for years said look its the heater box major repair. I know he doesn't care to work on Vw's its all good but it cost almost nothing to repair this badly designed item. I was ready to sell as is and take the hit but waited one more day when I could find my good flashlight and just refused to believe I had to take off the dash. So dont go to dealer unless you have the time and you point out whats wrong, they also said it was both the air compressor and a cracked heat box? find and locate it yourself I don't have a warranty on this 2002 1602,000 mile car, but I keep it running with good maintenance and all you who are kind enough to keep us all updated on your finds.
