- whats up people !! Had a Problem with my Dodge Ram heat not getting hot. So this video i dig into the heater recirculation door and do a little hack to help my heat get hotter. This modification will also work if your AC doesnt get cold. Hope this video is useful and may help others out that have the same problem .
iam not a certified mechanic and what i say or do is not a complete fix this is just something i did to help increase heat into my truck until i was able to fix the root of the problem.
Thanks for watching !!!
Recirculating cabin air passing it trough the heating core will make it warmer (only if your heating core is hot). However, if the heating core is partially plugged the air will not get that hot.
Recirculating air all the time will make the windows to fog up in some days likely in really cold or when there is a lot of moisture in the air.
Just pull off the blower fan under passenger dash (3 screws). remove the glove box . Reach a hand up through the hole where the fan was mounted while flashlighting through the window/grate behind the glove box. You'll see the recirculating air door and motor (Break away that plastic grate if you want). You can now see through to guide your hand to unplug the motor to the recirc door. I just did this to reinstall a broken door and sealed it permanently shut recurculating. Clean those fan blades on the blower fan while it's uninstalled... .
Thanks
Actually that is the proper operation of the door, if you are not getting a lot of heat, check your engine thermostat or maybe your heater core is starting to get plugged. Might need a coolant flush and while your are at it, change the thermostat. your heat should work just fine. Just some advice from a 15 year ASE Master Tech.
Just changed heater core so maybe themostate
Mine does the same thing, but why is it that it sounds as if the air is muffled, or stopped once the door closes? It's air restriction that I'm having
I own a 99 dodge ram 1500, changed the thermostat and did a coolant flush, still lukewarm. I read in a forum that the tubes that lead into your fire wall into heatercore should both be warm to the touch at operating temperature to ensure a good conditioned heater core, they both were warm. I have not tried this method with this circulating door.
I have one flushed my heater core and fluids I have amazing ac but no heat thermostat and housing changed and still no heat
Now watch your windows fog up during the winter. The recirculate door is for your A/C during the summer recirculating the A/C.
You might just saved me an arm and a leg. I was about to take my truck to the dealer because there is no heat in my truck during the winter. It just blows cold air. Your video might be my solution. Thank you.
You are the man. So many videos and so many options. Flushed entire cooling system including heater core 3 times, no heat. The blend door seemed to work. But after watching your video it was doing the same thing. Unplugged it, BINGO! I have heat.
THANK YOU SO MUCH!!! 😊💓☺
glad it helped !
On my 2008 1500 the door was just a little stuck. I cleaned it and put some silicone spray on it and it started working again. When the fan motor is turned off the door is supposed to shut. It should only open when the control is turned to a setting that is for recirculation. You may not need to unplug the motor if your door just needs to be cleaned and lubed.
I went to do this and I figured out the door had broken off and someone went t ahead and threw it away...-_- So I basically got a nice thick piece of cardboard cut it to size put it in put red tape all around it to hold it in and then I unplugged my actuator just in case. Figured I’d let y’all know if anyone else runs into not having a door at all.
Nice video
Yessss that would be me thanks I’ll do that now!!! Omg thanks
I switch from heat to AC After doing what he said and there is no problem both of them work great
This video got the heat working decently in my buddies 03 2500 Ram with the 5.9 Cummins. It's not hot hot but the truck is at least warm now, thank you!
The setup under the dash in this truck was a little different, but this video gives you just about everyone you need to know. You don't actually have to take all the dash pieces off, just the glovebox. Then you can pop the side panel off and reach through there with a screwdriver to push the lever to release the clip for the actuator and reach underneath with your other hand to pull it out.
Thanks again
Glad it helped ! any heat is better then none lol
Thanks man saved me some money on a cheap fast fix and got my girl to stop crying it was cold in the truck lol
That was a godsend my heater is working great now thank you so much for the awesome video and an easy way to fix this problem may God bless you and your family thank you
glad it helped happynew year
I have the same issues with my Dodge Ram 1500, 02. Will soon give it a go. Amazing video!
thanks hope you get it figured out
The actuator is snapped together you can also,be careful becouse the is little plastic gears inside but if the actuator is bad dosnt matter if they fall out,after popping bottom off you will see the shaft that tirns in cycle of hot to cold take a pair of small pliers and turn closing the door. The actuator is bad just replace when you can so you can use the switche property agin
Wow thanks for this, I just figured out why my truck sucks during the cold...the idiot before me removed the freaking door.
When doing this and permanently having it in recirculating, does defrost still work to get rid of humid air that would cause fogging of the windows?
I just wanted to say that ur video helped me a lot with my heat bc it was doing the same thing yours did and I drive an 2002 Dodge Ram 1500
Informative, I'm having that very problem this minute
thanks that was the most help i could find . I going to wedge a piece of plastic in there after I pull the wire .Good luck Brother!!!
Bro, you saved me a billion dollars not going to the mechanic. Thanks a million.
Or cut the wires and put a toggle switch in so you can set it to it original state if needed at any point. You’re already in there so might as well. Then you don’t have to pull everything apart if you need to hook that connection back.
Or you could just fix it and not be cheap?
See... My truck has a recirculation button so.. i don't understand why this would even be necessary.. is there not a recirc button in all 3gen?
@@yohan4ws - My '03 2500 5.9 3rd gen doesn't have an independant recirc button . Recirc is activated by turning the vent selector knob to the "7" or "8" o'clok position. For those concerned about defrost/defog, all you have to do is turn the vent selector knob to the 50/50 defrost/heat setting, which can be done by turning the vent selector knob to the 12 o'clock postiion. That said, does anyone know what causes the blend-door to not blend properly?
@@__WJK__ Blend doors are a common issue in our trucks from what I have read. The blend door itself, there's a plastic gromet on the end of the "flapper" (If you will) and it breaks, so it spins freely with the actuator while the door (flapper) lays flat and doesn't change direction of the air. There's lots of videos around that show this - and a couple of different fixes. unfortunately, the BEST fix is costly and involves removing the entire dashboard/hvac control from the truck.
Thank you. This was bugging me so bad. And it is 27 degrees here in Texas...saved my frozen ass. 😂
Outstanding video! Used it to fix my heater problem and worked like a charm. Good looking out sir.
👍
Totally worked. Great video, Thanks! Wish you would have shown how to disconnect the power cause that was the hardest part.
Sorry it's hard to get a camera in there lol
chuck kososky how you doin man I have the same problem I thought at first to have a bent door problem but all bent doors are good then I flash the heater core change the thermostat and still no heat I own a ram 1500 2011 any advise thank you have a good Sunday
@@enriquevaldovinos5544 blend door ? This is the door behind the dash that changes the air from hot to cold ormlm cold to hot sometimes it breaks and
stays in one spot. I had to remove my dash years ago to fix this..
@@AllThingsCool i have a 2008 dodge ram 1500 hemi...no heat at all..flushed heater core...changed thermostat..bleed the lines...checked my bend door and it opens and shuts like it suppose to do..spent all day..whatelse do i need to do..thanks
I found the best/easiest way was to put a small flat head on the right side opening and twist, then pull the plug out, but my clip had been previously destroyed.
Thanks for the video... Exactly what wasbwrong
recirculation door was broke
Hmm, so what would cause the blend door motor to open (vs close) and allow outside air in, even when both knobs on the dash are correctly set to "HOT" and "Vent Recirculation"(?) Would much rather fix the main cause vs disconnecting the blend-door motor.
This works ! Still feel I may have a bad heater core but this was definitely a huge part of my issue. Cool video helpful and useful. Fixed while I watched video in real time. I didn't have to remove anything more than the glovebox. Screw driver picked the plug right out. Great video 👍
Thanks I'm glad it helped ya
Thanks chuck appreciate the video hope it works would be nice to have heat in the power dog
good luck
Good video. Thanx. One thing I'd like to mention, they should change "glovebox" to "How much shitUcanfit box." Took more time going through everything in that damn thing than it did to correct the initial problem. Again, many thanx.
Thank you fir that upload, wish I would have been the first one to crack mine open. Some turd already did me the liberty of completely removing the door, now to put it all back together
Glad the upload helped
So what exactly causes the blend-door to not blend/operate properly?
Worked on 2002. Thanks
2014 Ram. Thinking of buying a Ford this time-just because Ram heaters are FREEZING!
Thanks solved it .
Minnesota.
Wisconsin here. My heat blows hot on passenger side but cool on drivers side. When I turn in the recirculate mode both sides blow how but my windows fog up. I did a coolant flush and it didn’t help. Would this help with that or would it just make my windows stay fogged up?
you think this would work on my 2016 lol bought my truck and it was warm and come to find out the best doesnt work and i think its gonna need a new heater core and is a HARD job or expensive if i have someone do it so i went without it all last winter llao.
Question for you....My AC blows very cold, but my heat sucks badly. Will I need to plug this back in to get my AC working when it gets warm?
Thank you very much!!
your welcome hope it helps

Flush the heater core and the cooling system.
I just watched a video with a guy with a 2010 RAM and he was saying he could calibrate the recirculation door with the blower level nob and pressing and holding on it.
Will try this on my 05 ram 1500 sometime this week 🤞🏾
Well why would it close when it’s supposed to be open? What is causing it?
Quick question
I have a 2013 ram truck with the 5.7hemi
Bought truck it had heat
Gradually the heat got cooler n cooler
Then boom heat completely out
Dont smell any coolant in the inside and pass side floor isnt wet
Could this be simple as a flush and maybe new thermostat
Or something common on these trucks thats quick
Truck has low miles
Thanks my friend for the good video I follow you from Argentina
I signed in , just to say THANK YOU , Happy you made this video
Thanks for the comment !
thank you
Thanks buddy I have a 02 dodge ram doing the same thing it will freeze you to death in the winter time thanks buddy I am subscribing to your channel now
Hi are you getting that much more heat
My truck is still luky warm.now there telling me to clean the a/c condenser. Mist be block.thank you
Did that affect your trucks ability to defrost properly throughout the winter just out of curiosity
So this actually worked for me! I unplugged the door, turned on the car and heater and after a while I heard a click and the vents became instantly warm. Does anyone know what the problem comes from?
Mopar junk pretty much
@@djscottymaxx haha...better than mopar is?
Thanks for the video seemed to be a nice quick fix for me
Glad it helped !
Stupid question hopefully someone can answer but I can't get my climate control to switch from my window to my face, that actuator that was there if I change that would it fix this problem? Or would I have to replace the one behind the radio? Please help
No outside air you will fog up windows in cold weather.
You need dry out side air.
So there.
Thats why the a/c compressor kicks on when its on defrost.
If you do what he did and make the recirculation door stay in the recirculate position, you very likely will have fogged up windows unless the air conditioner is on all the time to dehumidify along with the heat control being on. It would be a lot better to properly diagnose the problem and fix it right instead of what they call jury rigging.
most cars when they are put into the defrost selection mode the ac kisck in to DRY the inside air and defrost the class,, thats why your warm sweat and breath is fogging it up before you turn the defroster on.. also humid environments this would be a common occurance,, so make sure ac is on with the defresoter,, mine is automatic
On a ram 1500 2012 the defrost function does not allow recirculating on, only fresh air comes in blowing on the windshield. Some cars have the automatic setting for the AC to remove moisture, but probably uncommon on basic vehicles before 2010
Thanks. I'll see if that's the issue I have.
I've flushed the heater core several times but this could be the problem. 👍
Hope it helps ?
I just got home from work and would you believe it, The vacuum arm on my re circ door is leaving it on freash air.
Thanks a ton.
@@markbroad119 glad to hear u found your issue !!!!
Thanxxx brother great vidd it helped me thanks
Glad it helped
Great video.
Thanks
Hi going to flush heater core first , to make sure toal surface of core it hot, & then ,do what you just showed 👍😊 . Hopefully? Give heat back to driver's side & driver's floor? Thank Y😊u !
I have a different air set up in my 04 ram. Where his box is that opens and closes, mine is a plastic cage. I can't see anything inside opening and closing
Soo I took this door out in the summer because my ac wasn’t blowing cold or enough so that’s why my truck isn’t heating up that good in the winter so my bad 😂
Bravo good job and easy
Could you have just pulled fuse?
I did this and it worked for my passenger side heat. But my driver side is still not blowing out heat. Is there another door? I can’t find one
Thanks Chuck, trying to track down the source of my mysteriously vanishing heat. I'll have to let you know if this was my problem.
Hope this helps dont thing it's a permanent fix bit it's good for now
Does this work for the passenger side and defrost setting as well?
my heater works great, the problem i have is when i turn the switch to decide where the heat goes like to defroster it stays at the vents directly blowing on me. i need help figuring out whats wrong
Probably the mode doors are broken so do the right way take the dash out and rebuild the hvac box
I understand this quick fix but how does a person fix the incorrect door opening issue so it works properly and the actuator can remained plugged in?
It depends what your problem might be. Could be thermostat, plugged heater core, blend door issues you need to find out what's not allowing your heat to work properly
@@AllThingsCool Hi Chuck. I meant why would the re circulation door open when its not supposed to?
@@AhPhoey - Great Qs! A bit odd not a single person seems to know why the blend-door motor isn't working properly(!) Would rather correct the main cause vs unplugging the blend-door motor every Winter and Summer lol
Well this work on a 2010 Cummins I’m having the same problem. Trucks only blowing cool air.
Is this the same for 2014 Dodge RAM 3500?
When my ac or heater is on and I stepson pedal.it stops blowing then resumes when I let off?
1999 dodge ram 1500 5.2 this the same process?
Hi Chuck Kososky. My issue in my 2010 1500 Ram is i have no auto-lights, no heat, no a/c, no blower controls. I've been told this is the "heater control unit", but I can't find that part anywhere. I've also been told it's up under the dash and really difficult to get to. Can you help me understand what part this is, and what it's called? It's apparently connected to the dash sensor, which is why it is affecting my automatic lights.
The auto lights have a sensor that sometimes goes bad. The sensor detects how bright it is. Check that. Also check your fuse box. For the blower motor. That might be blown or the blower motor might of went out just a couple ideas
Great video brother neighbors 02 ram doing same thing I'll try this. I knew u tube was good for something stay warm homie lol
Hope it works !
chuck kososky hey chuck have a question I have a 2011 ram 1500 that has no heat I’ll change the 3 vent doors and flash de heater core change the thermostat and still no heat the heater core it’s not leaking the blowing motor works any tips. Thank you
@@enriquevaldovinos5544 I have the same issue did you get yours fixed?
Does this work on a Dodge Ram 2500 bighorn?
Ok so by doing that heater works what about the ac will it still be working
Will this stop the AC from getting cold?
Will that effect the AC
So is it a problem with the actuator then?
We're waiting not worried about the glove box
Do you have to disconnect at the power source?
that's what unplugging it does
03 Dodge Ram 1500 turn blower fan on and nothing. So ????
Any fixes for the shitty metal mopar uses for the bodies? Every dodge ive ever owned mini vans, trucks all have body rot
mine was the same real bad the bed of truck by fenders was terrible I just sanded down, put paint on it and threw on some over sized fender flares to cover the rot 🤷♂️
I’m haveing the same issue but only when I’m sitting still I got heat as soon as I start driving it goes cold
Would this fix the issue of having individual controls for driver and passenger side? My 2017 Dodge Ram blows cold air on the passenger side and hot air on the driver side when you turn the heat on.
That's ridiculous !!! A 2017 you shouldn't have any problems. No warranty left on it ? Not sure if this would help your situation it might be a blend door issue.
I have the exact same issue but I’m getting warm air on the pass side and cool air on drivers side driving me crazy lol 16ram2500
@@shawncrichton3009 I traded that in a 2 year ago. my 2020 Ram is far better lol
@@shawncrichton3009 that's the problem I have too, ever get straight?
Won’t this trap moisture in the cab and cause fogging of windows?
I haven't had any serious issues that my defroster couldn't handle
Ok thanks for video I’ll be trying this!
@@Bryce6565 yes this does most likely is in need of new thermostat or plugged heater core not this door to stop doing what it is supposed to do (this should allow outside air in winter to keep windows from fogging and no outside air in summer to keep cool )
@@Bryce6565 if you do this only way to keep windows from fogging is to crack a window defeating the purpose
Would this mess with the AC?
Here in TX much more concerned with AC than heat
It shouldn't all it does it block off the air coming in from out side so with the door closed it should just recirculate the air from inside cabin which keeps it warmer or colder depending on settings
will this cause the windows to fog up?
What was/is the issue do you know?
it could be a few things, bad heater core, need to flush your heater core , thermostat is bad blend door not working properly this is just a quick fix to get you buy
do you know what year ram this s for, my 13 is doing the same
Mine is an 03
My 13 is doing the same. Did you get yours fixed?
Mine's a '13. Same problem here
Same issue with my ‘13. Will try this fix tomorrow. Getting cold up here lol
If the door is kept closed is it going to affect your ac in the summer?
It should be cooler. It recirculated the cabin air instead of pulling from outside.
Where would this be on my 2013 ram
Do they is a door on the driver side also, cause only the driver side get cold air. Thanks
That’s my exact problem also, only driver side isn’t getting heat only cold air on drover side ...?
@@mustangmarcus302 i fixed it. on top of your blower motor fan, there is a door that aspire air from the outside of the truck, that blend door is broke . solution : some construction glue and glue it permanently. no more outside air coming in
@@mustangmarcus302 check blend door videos on youtube
Anyone know if this will work on the 2nd gens
thanks
Will this affect the ac in the summer time?
It actually helps your ac too. I had mine taped up there closed and the ac would be cooler if outside air comes in it won’t be
There is a reason the fresh air intake is there. It allows fresh air into the cab so your windows do not fog up. It should only be closed when you have the setting on recirculate or max .
Dont have an issue with my windows staying fogged
@@AllThingsCool would the true fix be to change the vent door motor that you unplugged. I dont want to fog up the windows
What if my recirculation door isn't there, like at all. What can I do without buying a recirculation door?
Your door might of broke off they do that look down into box see if its laying there
Do have to hook that back up when it's time to run your air conditioning
yes I would
@@AllThingsCool a/c gets colder if its allowerd to recirculate its own cooled air, and not draw in hotter air to compete with so i think this mod wold be fire...if you want freash air, your only otion now is to opena window
Would this be same for 2013 Ram 1500?
I’m curious to know this too.
My passenger side blows hot but my driver side blows cold
@@craigwoods5492 same here.
What if i get no foot heat just upper??
I have the same issue and it is usually the bottom door that opens and closes to let heat to the bottom is most likely broken there's a plastic gear that always breaks
Sometimes that door bends . Go to blend door . Com they have a good video. That ones a pain to fix
You need a new acctuwater
yup
This may help but I'm not convinced it resolves issue. It may get warmer but at the cost of fogging.
Low heat is usually a sign of a bad/clogged heater core.
Check fluid (coolant/antifreeze) level before anything. Low levels also cause poor heat.
yea just a quick fix
