BRIAN HOPE YOU AND YOUR FAMILY ARE WELL THROUGH ALL THESE THINGS HAPPENING AROUND US ALL THANKS FOR ALL YOUR EXPERTISE AND HELPING US POOR PPL FIX SND SAVE MONEY
perfect sense on this! if only you could stamp that into a curtain person I know! I also use that recirculation if I go through dusty contrition zones Lastly the ac is used for defrost too
One point to consider before using the ‘MAX’ setting is if you have superheated sir inside the vehicle, you may wish to pull in outside air that while hot may be 20 or more degrees cooler than what is in the vehicle. I also suggest opening windows for a few minutes to do thus initial air exchange. After a couple of minutes at the most use the ‘MAX’ setting for A/C.
FordTechMakuloco 2 problems with that 1) it could be hot enough in the car that you can not stand it, I have seen the greenhouse effect push interior temps close to 140 degrees 2) you can stand beside the vehicle for a minute or so and exchange the air bring in exterior air and also remove any gases that may happen from heated plastics. But yes once the interior air temp is near the exterior air temp recirculate the interior air to cool that air. You quickly will be cooling cooled air.
If you notice on some models the rpm's of the blower increases this is also one of the differences with AC vs max AC. Moves inside air faster. I use it once the inside air is cold and always on the expressway.
I had an '87 F-150 that I converted to R134a. It wouldn't get as cold as it did on R12. When I would use outside air, I would get fog out the vents. The evaporator wasn't quite cold enough to condense all the moisture out of the outside air so it would come out as fog. So, I just kept it on max and it worked fine.
Cooling the already cooled air in the passenger compartment is much easier than cooling the hot and humid air outside, as suck, the compressor can actually run LESS, placing less load on the engine, using less fuel. The only time I don't use the max ac function is on hit rainy days, fogs up the windows...
That's the problem for me, it ALWAYS fogs up the windows. Maybe not right away but it will within 15-20 minutes of driving. The only way to fix it is to either not use the Max setting or to turn the heat up slightly which totally defeats the purpose of using the Max setting in the first place. I hardly ever use the Max setting because of the fogging issue.
2010 Ford Fusion. Since moving to TX I’ve had my evaporator replaced, blower motor, and a/c control module and pigtail because of burn or melting around the connections
On my old 92 Civic, I had to run fresh air for the last ten minutes so the fresh air would blow over the evap and dry off any condensation. Otherwise it would smell horrible. I learned this from the dealer when I complained of the smell the first time soon after buying the car. It's the only car I've driven which had this set up....
On hot humid days, when there is a limited population in the building I manage, I shut the outside dampers and recirculate the inside air as long as the CO. stays at an acceptable level . It takes a load off of the chillers.
You could add that it is better to draw in outside air to the AC until the temperature inside the vehicle is at least as cool as outside. Sometimes your vehicle can be extremely hot to start with when sitting in the sun.
Hey Brian, on my 03 Ex, with the selector knob, i think it also operates a vaccuum motor that shuts off hot water to the heater core. it is just on the other side of the firewall in the engine bay. At least I think thats what it does so you recirc already cold air and the environment in the hvac box isn't subject to heat soak from the hot heater core even if the air flow isn't directed over it. does that sound right?
Thanks for the vid’s. love’em. I have a 2007 f150 and I was curious if there was a cabin air filter? I haven’t been able to find one but was just curious if this is something that needs to be changed periodically. Cheers
I know the question was posted 2 years ago but still is relevant now. I went thru that recently with my 04 5.4 f150. I researched it and determined that these type trucks do not have a cabin air filter. Neither does my 2000 4.6 F150. I just wonder where the crud is going. The 2000 4.6 A/C is still blowing cold with the original compressor 242K. Given Ford and others cheap parts and engineering now, its cheaper to keep her.
If using max ac on my 15 explorer would that stop making my vents wet? I don't understand why they get wet with moisture? Great video love your quick tips!
Quick question I know back in the past you talked about problems with ecoboost engines in f-150s. Have you heard of any problems with the 2.3 liter ecoboost engine in 2015 mustang? Great videos
Nice video tip, but a quick question...my 2015 F250 6.7 superduty has an AC button, MAX AC button, and a Re-Circ button. I TYPICALLY keep my system, heat or ac, in AUTO mode, but if I press the MAX AC button the Re-Circ button doesn’t light up.....is the MAX AC mode STILL using are-Circulated Air even though the button isn’t lit up?? Thanks!
Hey Ford Tech…any chance you can offer quick tips for the F150 electric Lightning ac musty issues. I am assuming there are subtle differences between the ICE version and the electric version?
Obviously you know I have the last generation Ford Crown Vic. An A/C video I'd love to see is one that shows us how to remove / clean (or) replace / and reinstall the cabin air filter. It took me a while to find mine and it's buried up under the dash behind that outside vent door which to me would mean removing the interior A/C unit and dash just to get to that foam filter which I know needs cleaning. Also, I'm having a bear of a time trying to locate the condensation drain tube. I don't know if it's plugged or not but the carpet on the front passenger side is damp and smells. I am sure my complaint applies across a number of different vehicle types within the Ford Motor Company.
James Barrow If carpet is wet & smells on the passenger side that's a tell tale Heater core issue lots of times. But you've solved it or sold the vehicle in 3 yrs I'm sure.
In your opinion how cold should the A/C on an 08 Expedition be blowing? This is my first year owning the car and at the start of summer our AC was blowing warm. I had 3 leaks fixed, the condenser and front condenser fan and a pressure switch replaced. The AC temp seems to fluctuate daily but it usually stays around 60 to mid 50s while idling and will eventually blow near 50 while driving. Our mechanic tells me that Fords don't blow as cold as GM's and on this year Ford its as good as it gets because its a small system. What do you think? Its a standard size Expy with dual and rear air.
B Scott Well that depends on your climate if you are in Arizona summer heat I would say up to 55 at the vents is ok. If you have front and rear a/c you should be using both and using max a/c.
Have you ever heard of the lights…well two lights actually the 1-2 and the 5-6 on the door key pad burning out with just 45,000 miles on my 2012 ford f150 platinum ecoboost truck as well as the heat is not coming through the drivers vents since 44,000 miles…I just find it strange that this truck is having these kind of problems with suck low mileage… I called ford about the heater problem, and they said it would cost around 1000.00 dollars to fix that problem… this has got me really aggravated since I really baby my truck…I normally drive my Acura, but still I don’t think I should be having these kind of problems this soon…also is that about the going price for the heater problem…they said a new key pad is around 70.00… thank you so much…
I have a 2013 Fusion. It has the auto controls not that manual knobs. On my unit it says auto and I just leave it on that. Does the computer control when it is on fresh and recycle? I know it adjust the fan up and down. Thanks!
I have a 2008 F350 Superduty and when I hit the re circulation button there is no change. Normally you will hear a difference in air flow and I stays the same. Not sure in which position its stuck on if open or closed but guessing open because I smell exhaust. Can you tell me where i could find this motor/flap on my 08 F350? Thanks
Does the auto HVAC systems in new Fords use max A/C as they cool in the auto mode? Always wondered about that. We have had 2 with EATC dual zone systems now and was always curious about that. I do realize how the MAX A/C works in a manual controlled HVAC.
klc317 The new systems have full control over the hvac system and adjust many things to get the vehicle cool faster. There are many inputs even humidity sensors now.
I have both. Max ac botton and that same recirculation button you pointed out. Why both thay do the same thing? What's different about them? I'm guessing max ac botton is just a short cut to fan on high and recirculation.
Any idea where to start 2005 ranger fx2 4 litre. Today on my way home my auto transmision stopped shifting, the o.d. off light came on and would not turn off. drove 15mph home and found out i also have no reverse
D Nelson Ford recommends defrost mode which always is in fresh air mode they have their reasons behind it but my pick still to get all the moisture out of the cabin is to use recirc. In essence dry the air in the cabin that is partly dry already.
I think generally speaking an ac system ( any) can reduce the input temp by 20 * or so max. So by reducing the input air temp you are multiplying your cooling power. I don't know where I pick that up or if it is correct or not..
680ecks That's right only in the most general sense. Some manufacturers have charts you can look up with base values for the norms with outside ambiant temp vs temp at inlet vent. It can vary a little from Make to model. But 20 degrees flat isn't a rule to go by. Even if you're IN Arizona & it's 110°, your vehicle should definitely not be only cooling the air to a vent temp of 90°!!!!!
Some engines have a greater load than others when running the AC decreasing mpg's. Diesel engines are hardly noticeable in mpg's with the AC. Four cylinders get really pulled down. Higher torque engines don't use as much fuel running the AC. In fact my truck does better with the AC cause it runs lean anyways, turning on the AC, the ecm richens the fuel ratio compensating for the lean running condition. It really depends on the vehicle in mpg with the AC running... Imo.
can you tell me WHY my 'temp dial control' wont work with the MAX option selected. it says way cold and turning the temp dial to hottest doesn't change it...stays at the coldest it can get. i can only control the fan speed but not temperature. many thanks.
I have an 05 f150 and every time I turn off the key it turns off my re circulation. Very aggravating and my work truck is an 07 f150 but it doesn't do that.
Actually, at least on the Fords I own, the recirculation button/setting is different than the Max button/setting. Yes, the Max feature does turn on recirculating but it also speeds up the fan motor a step. I suspect this is to compensate for not having the forced outside air.
It does not speed up the blower that is your perception because the door closed and the air source changed. Trust me if you saw the schematics you would understand.
FordTechMakuloco If what you say is true then what I perceive as as change in fan speed would happen when I press the recycle button, which it doesn’t. It only happens when I press Max.
Kinda a related question : I got a 14 f150 xlt it doesn't have auto climate could I buy the dash piece . Is that the difference ,would that give auto climate or is it more complicated. Is the dash interface the controller or is it a difference in the computer . I was thinking it was the interface itself that puts out the vac or electronic signal to control the hvac system .
680ecks It would be way more complicated than that starting with the electrical connectors. Also you would have to find a dealer willing to put as built data from another vehicle into it.
Do you have any idea where that is located on a 2013 f150? I want to spray some deodorizer in there, but cant find where the inlet is for recirculation
I have a 08 ford explorer when a turn the knob to full a/c it only blows thru the defrost vent and at times thru the front vents what could it be? Thanks
humblebeginings777 You need to verify all vacuum connections and the vacuum reservoir is intact. I have seen the check valve on the firewall passenger side cause this.
Hi. I have exactly the same Ford Expedition 2003. Fully agree with massage from this video. I have one problem with this mentioned motor - opening/closing those doors. My blower only blow air into my windscreen. When I remove glovebox and hit buttons nothing happen - door are still in the same position… What can be reason for that? Motor is brocken? Thank you in advance.
FordTechMakuloco I tried. Unfortunately nothing happened. Generally blown is only into windscreen. When I switch buttons from windscreen to any other position nothing happened…
Dorota Rdzanek If you have air flow problems then I would look at the vacuum source to the head unit. the air distribution motors are vacuum controlled where as the air inlet door is electronically controlled.
hi, do you have any videos on blend door removal / replacement for ford explorer 2005. I have seen videos where the bottom support of most doors in this model get damaged, I have found this piece in the glove compartment in my vehicle. I suspect the blend door is staying open as I can feel hot air coming thru the vents in the front. since I live in the desert region with temps at +45deg centigrade in summer, I never ever use the heater and I don't mind having the door locked to prevent hot air from getting in the car. Any Insight will be helpful.
john benjamin Desouza These are known for the recirc door failing off and allowing full flow of air from the outside in especially in the extreme cold or heat you will feel it. Lower the glove box and see if you can see outside light
FordTechMakuloco Hi, I cannot see outside light, thru the glove box. However since the ends of the recirc door are broken it would have fallen in the cage blocking the output from the blower motor. this probably explains the reduced qty of air on the window side vents. Is there a fix where I block out the AC inlet location below the wiper? thus no hot air comes into the car. should I use duct tape to block the inlet.
Hi I came across this with regard to my conversation above www.explorerforum.com/forums/showthread.php?t=284042 and here is how they choke the inlet www.explorerforum.com/forums/showthread.php?t=377401 How ever my question.. do you think duct tape can be used to block the inlet instead of the foamy substance?
98 Expedition, if I run max ac continuously I get a mildew smell the next time I run the ac. I've experienced this with other makes as well. If I use outside air it's fine. Any insight?
U know what's better than a/c. I had a 87 f250 with the vent windows and a sliding back window u open both of them and it cooled down way faster than a/c. They need to bring back vent windows
b52gnr I respectfully disagree about your ‘not when it 110’ The faster you get the superheated air out of your vehicle, the faster the A/C system can cool the air. Which will cool quicker? 150+ hot air or 110 hot air

if the max ac button does not change the position of the door, does that have to do with vacuum leak, or is it a faulty motor. the door under the passenger stays open so that outside air comes in and doesnt close when i press the max ac button.
That can be a few issues. These doors are either powered by an electric motor or they use vacuum from the engine to move the doors. The motors can fail, or the vacuum actuator can get stuck. There can be a wiring issue or vacuum lines can crack or break it can be the control panel not working correctly the door itself may be jammed and the motor/actuator is unable to move it and there is always just other weird issues that can happen
Is that the same door that controls the floor and windshield air? I have a problem with mine. When I press the Defrost button air still comes out of the vents, but very little air comes out of the top dash.
If you just run that on Auto, doesn't it also automatically go into "Recirc mode" (or Max AC if you will) when whatever conditions it looks for is met? I have a '05 Exp with the same AC panel and live in a hot sunny tropical country, and it seems when I start it after being parked outside that it goes into recirc mode automatically, and only drops out of it when the vehicle is cool enough. And I need to add a question, my rear AC seems to be running somewhat hot these days, not cooling well. The front main AC works well so the AC system is functioning. What I noticed is that the heat core in the rear is getting hot coolant circulating through it even with AC on, and I can't find any coolant cutoff valve like you have on the front heater core. Now, I could just disconnect the whole thing since I never have any use for heat in this country, but is there any cutoff valve or anything that shuts off the coolant flow to the rear heater core like it does on the front main heater core?
FordTechMakuloco Ok, so it doesn't cut the coolant flow to the rear heater core when in AC? I don't have that typical knocking sound from the actuator (already replaced the roof/floor actuator that had this sound), and it does get warm when turning the dial to hot, and then almost like ambient temp when turning it to cold for the rear. I'll have to take a closer look at the back, but I'm fairly sure the rear evaporator is getting cold as I do see the usual condensation water dripping from the AC drain above the tail pipe.
FordTechMakuloco I want to ask you a question about my 2013 Edge. I hear a rattling sounds from the right and left tyres when I ran over small pumps or cat's eye on the tarmac. Is it possible that my front shock absorbers are damaged and need a replacement? Ford dealer in my country claims nothing unusual about them and their is no oil leak from them but I think they need to replace it.
FordTechMakuloco May I send you some pictures of my shock absorbers "all 4 of them"? just take a look at it and see if they need a change or not. My regards.
My mom's (2014?) Escape, after getting it serviced for something else, now begins on max low temp/max fan and on MAX A/C... Anybody know why or had the same issue? Thx
What's the difference between the "Max A/C" button and the "recirculate" button on the Focus/Escspe 08-11 area. I know they both recirculate the air but not sure what the difference is if there's one.
I don't have an owners manual in front of me for that year, but on my '12 Ford Focus the recirculate button does what is shown in this video, and the "MAX A/C" button does that, PLUS turns the temp setting all the way down and puts the fan on high. Just a one-touch solution rather than turning all the knobs down separately.
My re-circulation door refuses to open with the AC on. Ford did tests and hotline call said this is normal and is part of the software. What do you think? Can the software override the manual buttons? 2015 Fiesta
wife fiesta is the same. The climate control works different than a normal heater. i senses temperature inside and out and only works that door under a few specific conditions. cant get her to understand how it works. ugh
Interesting. Thank you for sharing your experience. Hopefully the car won't start rolling up the windows on me too because it thinks it knows what's best...haha. I've just named my car Hal.
I know I’m 3 years shy but if anyone could answer please do. I have an 03 expedition and anytime I have front and rear ac on my car shuts off when I hit low rpms. Can anyone answer what the problem could be?
steve Fowler You would be surprised by the amount of people that don't know small things like this but that is why I do these videos to cover all aspects of Fords and cars not just the big jobs.
FordTechMakuloco And you do a great job...I was just trying to make a point about how little people know about cars these days vs when I was growing up and all boys knew them inside and out....keep up the good work....btw any inside scoop on the new 1 liter ecoboost engine? My 2105 fiesta has about 5K now and so far it seems to be an excellent engine.
I have a 2009 F150 4.6L 3V. I have the push button AC controls. My question is that I noticed when I place the air flow selector knob to 1 I feel no air being pushed by the fan motor out through the vents. Is this normal? I'm still under an extended warranty and am taking the truck in next Wed, 29July, for routine work (driveshaft "thunk" ) and also plan to ask them for any/all software updates for the PCM and TCM and SYNC updates for the newer phones/audio since 2009.. Should I have them fix the blower selector or motor fan selector switch? Friend at work said that no. He says no air is normal at lowest selection because it will use the inside air flow generated normally and route that out. Honestly, the hairs on my eyebrow curled up a tad... His answer just didn't seem to pass the ole sanity meter test. Appreciate any advise and hope you can answer before next week wed. Thanks very much and Keep on Keeping On. Tell Alex he does an amazing job with the videos.
Hawaiian F150 Yes there should be airflow at the 1 setting the fan is spinning although slow so the wet finger test is used to verify. Likely your resistor is failing get it changed.
Went to dealer - they wanted to charge $120 an hour to fix the resistor even though I have premium care warranty. They also said the greasing of the driveshaft hub and adding the SYNC available update are not covered under the same Premium Care warranty. Replacing the driver shaft YES -GREASING a big fat NO. My warranty expires in 2K miles or July 7, 2016 if I don't add the 2K miles.
hi my question is does the ac have a lot to do with heater. I have a 2004 ford 250 super duty 4x4 5.4 engine im having a problem with heat blowing luke warm air. I replaced actuator passenger side still have luke warm air. I have replaced , raditor , heater core, thermastat 1 yr ago

BRIAN HOPE YOU AND YOUR FAMILY ARE WELL THROUGH ALL THESE THINGS HAPPENING AROUND US ALL THANKS FOR ALL YOUR EXPERTISE AND HELPING US POOR PPL FIX SND SAVE MONEY
perfect sense on this! if only you could stamp that into a curtain person I know!
I also use that recirculation if I go through dusty contrition zones
Lastly the ac is used for defrost too
Thanks for the vids, I'm suprised you don't have more views. You do a good job of filming/explaining things, I enjoy watching
charginmahlazors My stuff allot of times is more speciality videos that you just wouldn't want to sit through unless you had that vehicle or problem.
Looking at a lot of videos with million +
It took my wife about 12 years to understand that the MAX AC was cooler to the car,
congrats! You've made it! ;-)
jdmeaux I told my wife to stop using it. It does nothing. At most use recycle.
Did not know that thanks for the info,you always seem to surprise me with new info thanks
One point to consider before using the ‘MAX’ setting is if you have superheated sir inside the vehicle, you may wish to pull in outside air that while hot may be 20 or more degrees cooler than what is in the vehicle. I also suggest opening windows for a few minutes to do thus initial air exchange. After a couple of minutes at the most use the ‘MAX’ setting for A/C.
Put it on max then start driving windows down for the first mile to remove the heat load from the vehicle then proceed.
FordTechMakuloco 2 problems with that
1) it could be hot enough in the car that you can not stand it, I have seen the greenhouse effect push interior temps close to 140 degrees
2) you can stand beside the vehicle for a minute or so and exchange the air bring in exterior air and also remove any gases that may happen from heated plastics.

It’s very good for driving by the sewage treatment plant as well!
2010 Ford Fusion. Since moving to TX I’ve had my evaporator replaced, blower motor, and a/c control module and pigtail because of burn or melting around the connections

This illustration is even easier to see on the Edge seeing that the airbox is right there in front.
You could add that it is better to draw in outside air to the AC until the temperature inside the vehicle is at least as cool as outside. Sometimes your vehicle can be extremely hot to start with when sitting in the sun.
Hey Brian, on my 03 Ex, with the selector knob, i think it also operates a vaccuum motor that shuts off hot water to the heater core. it is just on the other side of the firewall in the engine bay.

On a 1995 F250 (351w) why does my AC compressor run all the time? It even runs when I have the selector on “vent”.
Hey Ford Tech…any chance you can offer quick tips for the F150 electric Lightning ac musty issues. I am assuming there are subtle differences between the ICE version and the electric version?
Love the channel so helpful does this apply to 2006 ford rangers
yes
Max a/c does also turn off coolant flow to the heater core in the dash on some vehicles, for example I know rangers do this.
John Neuman Yes on the rangers it does as the valve use the same vacuum control circuit as the vacuum mode door on the fresh air inlet. Good info.
Obviously you know I have the last generation Ford Crown Vic. An A/C video I'd love to see is one that shows us how to remove / clean (or) replace / and reinstall the cabin air filter.

Have you ever heard of the lights…well two lights actually the 1-2 and the 5-6 on the door key pad burning out with just 45,000 miles on my 2012 ford f150 platinum ecoboost truck as well as the heat is not coming through the drivers vents since 44,000 miles…I just find it strange that this truck is having these kind of problems with suck low mileage… I called ford about the heater problem, and they said it would cost around 1000.00 dollars to fix that problem… this has got me really aggravated since I really baby my truck…I normally drive my Acura, but still I don’t think I should be having these kind of problems this soon…also is that about the going price for the heater problem…they said a new key pad is around 70.00… thank you so much…
I have a 2013 Fusion. It has the auto controls not that manual knobs. On my unit it says auto and I just leave it on that. Does the computer control when it is on fresh and recycle? I know it adjust the fan up and down. Thanks!
does the 2003 ford expedition Eddie Bauer 5.4 l have a cabin air filter?
I have a 2008 F350 Superduty and when I hit the re circulation button there is no change. Normally you will hear a difference in air flow and I stays the same. Not sure in which position its stuck on if open or closed but guessing open because I smell exhaust. Can you tell me where i could find this motor/flap on my 08 F350? Thanks
Does the auto HVAC systems in new Fords use max A/C as they cool in the auto mode? Always wondered about that. We have had 2 with EATC dual zone systems now and was always curious about that. I do realize how the MAX A/C works in a manual controlled HVAC.
klc317 The new systems have full control over the hvac system and adjust many things to get the vehicle cool faster. There are many inputs even humidity sensors now.
I have a 2004 Ford Expedition and the front a/c keeps blowing hot air instead of cold air, the back blows cold air. Any suggestions?
My 2005 Focus recirculation mode is not working.
It used to work some times but now it stoped completely. What could this be?
Thanks
I have both. Max ac botton and that same recirculation button you pointed out. Why both thay do the same thing? What's different about them? I'm guessing max ac botton is just a short cut to fan on high and recirculation.
Blake Langley One is recirc air the other is recirc air and a/c
how do you replace the ac filter if that makes any sense on a 2003 ford expedition ????
Any idea where to start 2005 ranger fx2 4 litre. Today on my way home my auto transmision stopped shifting, the o.d. off light came on and would not turn off. drove 15mph home and found out i also have no reverse
I keep our Explorer on auto, but it has a recirculating button, and a max ac button.
Could you expand/education everyone on how this works with a fogged windshield. I do not know what Ford recommends for moisture in the cabin.
Thanks
D Nelson Ford recommends defrost mode which always is in fresh air mode they have their reasons behind it but my pick still to get all the moisture out of the cabin is to use recirc. In essence dry the air in the cabin that is partly dry already.
Hitting the recalculation button also gives your fan motor an extra boost so it blows more air.
TIKIMAN198 The fan motor does NOT change speed. It sounds louder due to the door moving to the recirculate position.
Jason Beeman If you put your hand up you can feel it blowing faster.
I think generally speaking an ac system ( any) can reduce the input temp by 20 * or so max. So by reducing the input air temp you are multiplying your cooling power. I don't know where I pick that up or if it is correct or not..
Yeah it's all about the heat load on the system.
680ecks That's right only in the most general sense. Some manufacturers have charts you can look up with base values for the norms with outside ambiant temp vs temp at inlet vent. It can vary a little from Make to model. But 20 degrees flat isn't a rule to go by. Even if you're IN Arizona & it's 110°, your vehicle should definitely not be only cooling the air to a vent temp of 90°!!!!!
Something wrong with a car that can only manage a 20 degree reduction.
Some engines have a greater load than others when running the AC decreasing mpg's. Diesel engines are hardly noticeable in mpg's with the AC. Four cylinders get really pulled down. Higher torque engines don't use as much fuel running the AC. In fact my truck does better with the AC cause it runs lean anyways, turning on the AC, the ecm richens the fuel ratio compensating for the lean running condition. It really depends on the vehicle in mpg with the AC running... Imo.
can you tell me WHY my 'temp dial control' wont work with the MAX option selected. it says way cold and turning the temp dial to hottest doesn't change it...stays at the coldest it can get. i can only control the fan speed but not temperature. many thanks.
I have an 05 f150 and every time I turn off the key it turns off my re circulation. Very aggravating and my work truck is an 07 f150 but it doesn't do that.
Actually, at least on the Fords I own, the recirculation button/setting is different than the Max button/setting. Yes, the Max feature does turn on recirculating but it also speeds up the fan motor a step. I suspect this is to compensate for not having the forced outside air.
It does not speed up the blower that is your perception because the door closed and the air source changed. Trust me if you saw the schematics you would understand.
FordTechMakuloco If what you say is true then what I perceive as as change in fan speed would happen when I press the recycle button, which it doesn’t. It only happens when I press Max.
Kinda a related question : I got a 14 f150 xlt it doesn't have auto climate could I buy the dash piece . Is that the difference ,would that give auto climate or is it more complicated. Is the dash interface the controller or is it a difference in the computer . I was thinking it was the interface itself that puts out the vac or electronic signal to control the hvac system .
680ecks It would be way more complicated than that starting with the electrical connectors. Also you would have to find a dealer willing to put as built data from another vehicle into it.
What do I check rear passenger ac not blowing resistor change actuators changed heat vent door open and closing on 2003 ford exp xlt
Do you have any idea where that is located on a 2013 f150? I want to spray some deodorizer in there, but cant find where the inlet is for recirculation
I have a 08 ford explorer when a turn the knob to full a/c it only blows thru the defrost vent and at times thru the front vents what could it be? Thanks
humblebeginings777 You need to verify all vacuum connections and the vacuum reservoir is intact. I have seen the check valve on the firewall passenger side cause this.
FordTechMakuloco Thank you.
Hi. I have exactly the same Ford Expedition 2003. Fully agree with massage from this video. I have one problem with this mentioned motor - opening/closing those doors. My blower only blow air into my windscreen. When I remove glovebox and hit buttons nothing happen - door are still in the same position… What can be reason for that?
Motor is brocken? Thank you in advance.
+Dorota Rdzanek This one would only do it if the a/c was already on try that.
FordTechMakuloco
I tried. Unfortunately nothing happened. Generally blown is only into windscreen. When I switch buttons
from windscreen to any other position nothing happened…
Dorota Rdzanek If you have air flow problems then I would look at the vacuum source to the head unit. the air distribution motors are vacuum controlled where as the air inlet door is electronically controlled.
FordTechMakuloco Thx. Where air distribution motor is located. Did you do video where by chance ;) will be visible?
It mounts to the side of it, it is a small vacuum motor and the manual states the dash must come out.
that construction zones...
Are there any Ford vehicles that have cabin air filters?
Windstars and freestars do I know while most newer ones have them like fusions, edge and explorer
What about fuel economic in this option?
How can find my 2001 ford escape xlt A/C reset button?
hi,
do you have any videos on blend door removal / replacement for ford explorer 2005. I have seen videos where the bottom support of most doors in this model get damaged,
I have found this piece in the glove compartment in my vehicle. I suspect the blend door is staying open as I can feel hot air coming thru the vents in the front. since I live in the desert region with temps at +45deg centigrade in summer, I never ever use the heater and I don't mind having the door locked to prevent hot air from getting in the car. Any Insight will be helpful.
john benjamin Desouza These are known for the recirc door failing off and allowing full flow of air from the outside in especially in the extreme cold or heat you will feel it. Lower the glove box and see if you can see outside light
FordTechMakuloco Hi, I cannot see outside light, thru the glove box. However since the ends of the recirc door are broken it would have fallen in the cage blocking the output from the blower motor. this probably explains the reduced qty of air on the window side vents. Is there a fix where I block out the AC inlet location below the wiper? thus no hot air comes into the car. should I use duct tape to block the inlet.
Hi I came across this with regard to my conversation above
www.explorerforum.com/forums/showthread.php?t=284042 and
here is how they choke the inlet
www.explorerforum.com/forums/showthread.php?t=377401
How ever my question.. do you think duct tape can be used to block the inlet instead of the foamy substance?
98 Expedition, if I run max ac continuously I get a mildew smell the next time I run the ac. I've experienced this with other makes as well. If I use outside air it's fine. Any insight?
Mildew on fins of evaporator core.
U know what's better than a/c. I had a 87 f250 with the vent windows and a sliding back window u open both of them and it cooled down way faster than a/c. They need to bring back vent windows
Not when it's 110°.
b52gnr I respectfully disagree about your ‘not when it 110’
The faster you get the superheated air out of your vehicle, the faster the A/C system can cool the air.
Which will cool quicker? 150+ hot air or 110 hot air

if the max ac button does not change the position of the door, does that have to do with vacuum leak, or is it a faulty motor. the door under the passenger stays open so that outside air comes in and doesnt close when i press the max ac button.
That can be a few issues. These doors are either powered by an electric motor or they use vacuum from the engine to move the doors.
The motors can fail, or the vacuum actuator can get stuck.
There can be a wiring issue or vacuum lines can crack or break
it can be the control panel not working correctly
the door itself may be jammed and the motor/actuator is unable to move it
and there is always just other weird issues that can happen
Is that the same door that controls the floor and windshield air? I have a problem with mine. When I press the Defrost button air still comes out of the vents, but very little air comes out of the top dash.
n310ea No that is the mode door you are talking about. Yours are vacuum on the expedition.
I'm sorry, I have an '05 Mercury Grand Marquis LS that I have that problem with.
Why does the 2005 f150 does not have a cabin filter?
If you just run that on Auto, doesn't it also automatically go into "Recirc mode" (or Max AC if you will) when whatever conditions it looks for is met? I have a '05 Exp with the same AC panel and live in a hot sunny tropical country, and it seems when I start it after being parked outside that it goes into recirc mode automatically, and only drops out of it when the vehicle is cool enough.
And I need to add a question, my rear AC seems to be running somewhat hot these days, not cooling well. The front main AC works well so the AC system is functioning. What I noticed is that the heat core in the rear is getting hot coolant circulating through it even with AC on, and I can't find any coolant cutoff valve like you have on the front heater core. Now, I could just disconnect the whole thing since I never have any use for heat in this country, but is there any cutoff valve or anything that shuts off the coolant flow to the rear heater core like it does on the front main heater core?
Skauber Your temperature blend actuator has failed in the rear I have two videos on this on how to change both actuators back there.
FordTechMakuloco Ok, so it doesn't cut the coolant flow to the rear heater core when in AC? I don't have that typical knocking sound from the actuator (already replaced the roof/floor actuator that had this sound), and it does get warm when turning the dial to hot, and then almost like ambient temp when turning it to cold for the rear. I'll have to take a closer look at the back, but I'm fairly sure the rear evaporator is getting cold as I do see the usual condensation water dripping from the AC drain above the tail pipe.
Skauber I have never seen a coolant control valve on the rear heater lines no.
FordTechMakuloco Ok, thanks for the advices! :) I'll dig into the rear AC and check the temp blend door, must be something going on there.
Any Edge videos coming soon? specially 2011-2014?
feduo45465 Nothing at the moment.
FordTechMakuloco I want to ask you a question about my 2013 Edge.
I hear a rattling sounds from the right and left tyres when I ran over small pumps or cat's eye on the tarmac.
Is it possible that my front shock absorbers are damaged and need a replacement?
Ford dealer in my country claims nothing unusual about them and their is no oil leak from them but I think they need to replace it.
feduo45465 Small rattle sounds over light bumps is almost always the stabalizer links.
FordTechMakuloco May I send you some pictures of my shock absorbers "all 4 of them"? just take a look at it and see if they need a change or not.
My regards.
Don't it make the pump run constantly, or is that one of the myths as well?
olsem101 Nope sure doesn't.
My mom's (2014?) Escape, after getting it serviced for something else, now begins on max low temp/max fan and on MAX A/C...
Anybody know why or had the same issue? Thx
What's the difference between the "Max A/C" button and the "recirculate" button on the Focus/Escspe 08-11 area. I know they both recirculate the air but not sure what the difference is if there's one.
joshg678 nothing
I don't have an owners manual in front of me for that year, but on my '12 Ford Focus the recirculate button does what is shown in this video, and the "MAX A/C" button does that, PLUS turns the temp setting all the way down and puts the fan on high. Just a one-touch solution rather than turning all the knobs down separately.
My re-circulation door refuses to open with the AC on. Ford did tests and hotline call said this is normal and is part of the software. What do you think? Can the software override the manual buttons? 2015 Fiesta
wife fiesta is the same. The climate control works different than a normal heater. i senses temperature inside and out and only works that door under a few specific conditions. cant get her to understand how it works. ugh
Interesting. Thank you for sharing your experience. Hopefully the car won't start rolling up the windows on me too because it thinks it knows what's best...haha. I've just named my car Hal.
My 04 expedition has selector I never knew
What about Fords that have a recirc button and a max A/C selection on the touch screen?
jtoddk98 Same thing recirc button is for when you are in heat mode or ambient air mode where as max a/c is just that recirc and a/c
Will you please tell me where is the ac drain line on the expedition EB 2004?
Behind passenger head on firewall.
I have a 03 FORD EXPLORER,when i put it on panel or max ac im losing air to the floor what can it be
Cracked or broken vacuum line under the hood
MY OANEL ON 98 F150 FLARESIDE, CANNOT GET FLOOR A/C. I CAN GET IT ON DEF/FEET......NOT A/C OR MAX A/C ? ANY WAY TO HACK THE COMPUTER ?
I know I’m 3 years shy but if anyone could answer please do. I have an 03 expedition and anytime I have front and rear ac on my car shuts off when I hit low rpms. Can anyone answer what the problem could be?
So what's better AUTO or Max AC ?
Jason Adamson max is the best, auto will only use it part time.
Out of topic but I'm getting a p1440 engine code in my 2013 Ford Fusion ecoboost any idea what it could be? Thanks!
Junior Ocampo P1440 is not even coming up as a code on the fusion, you sure it is not a P144A
Yes sorry that's the code
Yeah so what if you don't want stuffy air to be recirculated all the time.
SilentServiceCode Then you turn recirc off and the system will eventually catch up
Thanks man. My dumbass wasnt using the recirculating air button
I thought everyone knew that....or at least everyone who had a Dad who told him how it worked when he was about 13 years old....about 45 years ago :)
steve Fowler You would be surprised by the amount of people that don't know small things like this but that is why I do these videos to cover all aspects of Fords and cars not just the big jobs.
FordTechMakuloco
And you do a great job...I was just trying to make a point about how little people know about cars these days vs when I was growing up and all boys knew them inside and out....keep up the good work....btw any inside scoop on the new 1 liter ecoboost engine? My 2105 fiesta has about 5K now and so far it seems to be an excellent engine.
Where the evap drain on a 7.3 ford diesel
I have a 2009 F150 4.6L 3V. I have the push button AC controls.
My question is that I noticed when I place the air flow selector knob to 1 I feel no air being pushed by the fan motor out through the vents. Is this normal?
I'm still under an extended warranty and am taking the truck in next Wed, 29July, for routine work (driveshaft "thunk" ) and also plan to ask them for any/all software updates for the PCM and TCM and SYNC updates for the newer phones/audio since 2009.. Should I have them fix the blower selector or motor fan selector switch?
Friend at work said that no. He says no air is normal at lowest selection because it will use the inside air flow generated normally and route that out. Honestly, the hairs on my eyebrow curled up a tad... His answer just didn't seem to pass the ole sanity meter test.
Appreciate any advise and hope you can answer before next week wed. Thanks very much and Keep on Keeping On. Tell Alex he does an amazing job with the videos.
Hawaiian F150 Yes there should be airflow at the 1 setting the fan is spinning although slow so the wet finger test is used to verify. Likely your resistor is failing get it changed.
FordTechMakuloco Thanks! Will have them check it Wed. Thanks for super fast reply.
Went to dealer - they wanted to charge $120 an hour to fix the resistor even though I have premium care warranty. They also said the greasing of the driveshaft hub and adding the SYNC available update are not covered under the same Premium Care warranty. Replacing the driver shaft YES -GREASING a big fat NO. My warranty expires in 2K miles or July 7, 2016 if I don't add the 2K miles.
Forgot to add that they estimated me 5 hours at $120 p/hr but weren't sure and it could be more b/c of the fan and the update for SYNC.
Doesnt max a/c always have the compressor clutch engaged versus non-max where the clutch will cycle?
No.
Why would they even have a max ac button? Why not just recirculate the air all the time?
There are some situations where it would fog up the windshield.
I HAVE A/C - MAX A/C WHICH ONE ? 98 F150 FLARESIDE.
max
hi my question is does the ac have a lot to do with heater.
I have a 2004 ford 250 super duty 4x4 5.4 engine im having a problem with heat blowing luke warm air.
I replaced actuator passenger side still have luke warm air. I have replaced , raditor , heater core, thermastat 1 yr ago
I hate Max A/C. I never use it
