    is the line from the evaporator getting cold as it comes out of the firewall? If not, add more refrigerant. If yes, your blend door is not working, and you will have to check the blend door actuator. Let me know if you need instructions for this.

The blend door is inside the box where the air flows from outside into the car. The air goes through the air conditioner first, then it goes to the blend door. When the door is open, the air will then go thru the heater and get hot. When the door is closed, the cold air will come out the vents. In this way, the blend door controls how much air goes thru the heater. When you are running the A/C, you want the blend door closed. If your a/c compressor is working but you are not getting cold air, the blend door may be stuck open.
My book shows your blend door is behind the glove box. It also says your door is controlled by a cable. What you should do is look behind the glove box to see what happens when you change the temperature on the panel. It should move a cable behind the glove box that turns a lever on the door. The cable should turn the lever as far as it will go. If it doesn't do that, it is either broken or needs to be adjusted. It may have slipped out of it's clamp. To adjust, loosen the clamp, turn the knob to cold, and push the door fully closed, then tighten the clamp.

Let me know if it doesn't look like what I'm saying or if you have other questions.

Heat and air conditioning temperature control does not work. Why doesn't ac blow cold air even though compressor runs and the refrigerant line gets cold? Only hot air comes from vents.


Probably the air blend door is not functioning properly. This can be caused by a vacuum leak; bad actuator; or bad vacuum check valve.

Air cinditioning wont stay on, it switches to heat and wont shut off


What do you mean when you say it wont shut off? is it blowing hot air or do you just feel a lite flow of hot air even if you have the settings to cold?

If this is the problem that you always feel hot air at low flow and the ac goes to hot air then i would say one of two things, first if you have the selector to cold and you feel hot air then there may be a problem with the blend door, this door move to allow hot or cold air, the door may be broken or just a bad motor that controls it. keep in mind if the ac system shuts down for any reason the air then will be warm, it will be about the same temp as outside and maybe a little hotter.

this problem almost sounds like the ac compressor shuts off and then you are getting the outside air which is hot, there are many reasons for the compressor to shut off, it could be the compressor clutch heating up and disengaging , this would be due to a bad compressor clutch.

another reason is the fans are not working, the best thing to do is when the system starts to blow warm check and see if the compressor is running, start engine and look at the front of compressor, with ac off the front of it will not move, and then with ac on the front will spin, check it out and let me know, if it blows warm air and ac is not working then it may be compressor problem but if you are getting warm air and the compressor is spinning then it may be a door problem.

This is hard to check with out testing the system, so i listed a few things to check and let me know the out come. also the ac blows cold for how long before it gets hot air blowing out of the vents, good day.

It blows out hot air even when the air in the front is cold


Hard to read your question, do you mean it blows cold air out of the front vents and hot air out of the rear passenger vents?

If the air coming out of the front is just cool and not cold, and the rear vents are warm, you have low freon and need to have it serviced.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

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

On the bottom of the air unit is the lever that changes temps. It likes to fall out of place.I propped mine back with a piece of half-inch copper pipe a couple of years ago.Remove glove box then panel on front side of console to access.
