Ford Excursion :: Air Blowing Hot Out Of Vents When Cool Outside
May 10, 2014
As the season has started to warm, I noticed when I have my air temp set to 60 and only using the vent and have not selected AC I have hot air coming out of my vents. After doing some research it appears that I may have a bad Air blend actuator, bad air door or something else. I took my truck to the dealer to get my fuel filter changed and asked if they could diagnose the hot air issue. Not being a mechanic I told the service mechanic the problem and he says the AC compressor always kicks in on fords even if the AC is not selected and maybe I have a leak and he seemed to think it more than likely was not the air blend actuator or blend door.
I told him I had no idea that the AC compressor always kicks in even with it not selected. I knew it kicked in for AC and for defrots but didn't think it did for anything else. He said since the 90's all fords did. Well I get a call that after diagnosing the system, they believe the freon is low. I just have my doubts and wonder now if I should've just tried to take the air door actuator off and test along with sticking something in the air blend door whole and verifying it was moving.
I was hoping someone that knows more than me can verify if the AC compressor kicks in even when it is not selected when I have the temp selector set to low 60 degrees. Does it make sense that I would have hot air blowing out of the vents with the temp set on low even when it is cool outside. All of my temp controls work moving from defrost, vent to heat as I can feel blowing out of the different zones.

We are having an issue with the front air not blowing cool all the time. Sometimes if we hit a bump or something its like something is jogged and it blows colder but the rear air always blows cold. Also the front air blows colder with the rear air on. I put gauges on it and I have the right amount of refrigerant in it. What I can do.

My 02 V-10 Ex seems to be blowing Air from the front vents up to the Defrost unless it go through a series of events-- Hit Auto then forward Air then the fan has to be a 4 only. It will blow forward vents then go back and forth from theirr to the defrost. Also the Temp seems to be much hotter then it should.
Took a interstate trip this weekend though and it seems to blow much colder and do a little bit better staying in the front vents however still goes back and forth. Im in FL and its HOT!!!! The only thing I know is that its a vacuum system.. and that again its HOT in the truck as a daily driver.

Heat is blowing through my dash vents in front of the windshield with the controls OFF!

Looking to get the A/C working on my '78 F150 with integral (factory) A/C system. It is complete, but it seems to be blowing warm air as opposed to cold.
When I turn on the A/C, the compressor engages and the blower switches to the dashboard vents. I waited for a minute or two, but no cool air.
The sight glass has a silver line running through it. I assumed this was full? It would be black if it was low/empty.

2004 Foed Freestar, the A/C has started blowing less than cool air in the past sveveral days. I'm assuming its low on refrg. but how does one check by visual inspection? If it is low will a simple re-charge kit w/guage and super dupper leak sealant do the trick? I saw a kit at Advance Autoparts for manufactured by Interdynamics. It had a guage w/trigger release for can content and three 12oz. cans of R134a. Will this kind of kit work?

AC works, but only drops temp by 15 degrees. Pressures 40/150 after adding some 134a.
Compressor runs continuously at idle. (I don't know if this is correct or not.)
Not sure what the issue is.

I took my truck to a friends express lube to have some freon added to it. My truck has been blowing cool air, not cold. So i thought it might be low on freon considering its a 2000 f-150 w/ 145,000 miles. He took a pressure gauge to it and said it is over charged, the pressure was high.

In my 08 Expedition I notice the a/c compressor cycles on for 18-25 sec. then off for about the same. This is with an ambient temp of about 75f. A/C seems to be blowing cool air-never was really cold since new. The idle drops/surges a bit when the a/c kicks on also-which is what grabbed my attention. Is this a normal or is it short cycling?

03 F350 7.3PSD... A/C blows cool on max only but does not blow real hard on high.
Blower motor is loud like it is blowing but just not coming out of vents. On reg A/C blows hot, actually blows hot on all other settings.
A/C compressor is on but blows hot through vents. I am thinking blend door and or something else. Thing is I am not sure what or where to look and how do I check?

I have a 1998 f150 4.6 that has a problem with the heating system. It's blowing out a little warm, but "far" from what it should be. ( on a scale from 1-10, I'd rate it about a 3) I am puzzled because I flushed the radiator, changed the thermostat, and there a no signs of heater core leaks inside,hose leaks on firewall, or radiator/water smell present. I don't know if this has anything to do with it, but I did notice the top radiator hose was hot, but not the bottom. I don't know what else to look for.

I have an '08 350 with less than 82K miles. My problem is the AC. The vents on the passenger side blow out cool air and all the vents on the driver's side blow out hot air. Even the vents in the backseat, the left one blows hot air and the right one blows cool (my son informed me of this as I hadn't even checked). As you can imagine it's very uncomfortable driving around in this CA heat every day, especially since the driver side vent in the center cannot be completely closed. What could cause this?

I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?

Had a few warm days last week and noticed a lack of cooling from the HVAC system. Local temps cooled off a bit but I decided to see what I could find out before I got hot again.
Started playing with the system in the driveway and discovered good cooling capacity on the passenger side but just mildly cool air coming out of the drivers side vents. This seemed to be true on both the front and back. I hooked by laptop up and noticed single digit temps at the evaporator. When I brought the temps down on the climate control the right side exchanger would get down to around 12C but the Left would struggle to get to 22C and if I moved the passenger side requested temp up the drivers side exchanger temp would follow even though the requested temp on the drivers side was low. There was a display for the Left and Right regulating valves but they seemed parked at 0.0 unless I made a cabin temp change.
I am guessing the left regulating valve is the problem but know nothing of how this system works. 2004 Phaeton V8 ....

I have a 2000 Suburban which is only blowing hot air from the vents. If I turn the temp selector to cold it still blows hot air. Even when I press the button for AC it still only produces hot air.

My air conditioning just stopped blowing cool air. While the blower still operates properly, the air is coolest (but not nearly cool enough or normal) at the extreme right passenger vent, then is progressively warmer toward the driver's side, with the warmest vent being the extreme left at the driver's side next to door. I'm inept at mechanics in general, and especially with autos, which is why I bought the BMW (which tells you when it needs service) to begin with. The only thought I had was that I recently had the car detailed and the engine washed at the BMW dealership. Could something have come loose when power washed under the hood? I'm hesitant to take it back since my last experience was not a good one. I have of course checked all the settings.

My 2011 F-250 just started having a weird heater problem. My truck heater gets up to temp just fine but after cruising down the highway for about 15 minutes or so it starts blowing out cool air. I can turn the controls to defrost and back again and it blows warm, not hot but warm then cool again. It just started a couple of days ago. Temp gauges show normal temp also.

Had a question about the rear a/c cooling on my 2009 GX 470 - the last few days have been nice enough to warrant using the A/C. I noticed though, that the 4 rear vents seem to not be producing any cool air - kind of a problem when I have an overheated Boxer dog that would love some cool A/C. Any thoughts? I have the rear A/C on, all the way to the - or minus sign and the fan speed to Auto.

All of a sudden the AC in my 2007 Passat 2.0 stopped blowing cold air. It worked great yesterday. I'm worried that it might be the compressor because I don't have the 1000+ dollars to have it replaced. I bought the car in 2009 but I'm almost sure it is out of warranty because I've put more than 50,000 miles on it. I read some posts that the AC might need to simply be recharged ?????

New owner for the passat 2003 gls passat 1.8T. I turned on the AC and its not blowing cool air. Looking for DIY to fix my AC problem.

It reached 93 here today and it has always taken too long for my AC to reach a cool temperature. I have never had the AUTO setting slow the fan down even at highway speeds. I am moving to TX in the next few months and I already know what it is like driving it down there...HOT! I could really like improving the efficiency of the AC of my Ex.
Can I use the same insulation used for home AC lines on the truck? Is there any high-temp insulation I could fun over the lines? I found a coolant shut-off valve for the heater core on 7.3 trucks, but not for the 6.0. Is there an equivalent for us with the 6.0?
