Nice to hear, John. The next issue is going to be heater core issues! Almost all the viewers of this video found out they had heater core issues. If flushing doesn't work, it is a $3000 repair according to some.
Thanks for the video the heater core is Split, top half is passenger side, bottom is drivers side, when core plugs up, you loose the bottom, which is the driver's side heat…go to tie favorite mechanic and have him flush your coolant system.
@@unclemarksdiyauto that’s why they need to take it in and have a radiator company or some other reputable mechanic to make sure it’s flush properly. And also to pressure test it to make sure there’s no leak. That’s often times what guys run into when they do it on their ownall of a sudden their heater core is no longer plugged but it leaks
@@gman8557 I agree! The problem is most will never go to a real rad specialty shop. They figure any shop or they themselves can do it. Of course the results are based on where you take it, not 9n how much money you did not spend.
Hey UncleMark, appreciate your videos. I have a 2013 ram 1500 that I bought in 2020, the seller let me know the drivers side heat doesnt work before buying it. He was thinking the heater core needed replaced but didnt want to rip the dash out to do it. After doing some research, I think I may have it figured out (not fixed). So, my truck just has the single climate control and works fine in the summer with the AC blowing cold on both sides. I found some images showing that there are 5 blend doors for various features of the climate control: recirculation, foot vents, defrost vent, passenger vents and drivers vents. My guess is that the actuator for the drivers vents is stuck in one position. This allows the AC to work just fine in the summer, but in the winter its only able to blow a few degrees above ambient. I googled "2013 Ram 1500 vent schematic" and found some good graphics. I have access through work to get my hands on a bore scope with remote control tip, perhaps I will shove that in my driver side vents to see if I can see the particular blend door and prove that it is/isn't working.
That sounds like a good plan Alex. I was doing some more unrelated work to this truck The owner just had the heater core flushed ad says that seems to have made a difference. (Just a FYI) Please let me know what you find. You can also shoot me a email. Address listed in my about section.

@@waynemetcalf4254 or get rig your alternator to make 110 volts and get a electric heater. (Sorry, that’s cruel.) I think we all need to start driving stuff from the 1970s where your could easily swap the core out.
In theory, yes. You should be able to move the blend door with the actuator out. Use your finger or a screw driver. Some times the blend door can fall apart, and then it does not move properly when the actuator does. Do you have no heat on drivers side only? Or what is your problem with truck?
Why did you remove the actuator? You could see the lever was going up and down when you took out the glove box which means the blend door is opening. Maybe I missed something?
@@andrewsams335 Good to know how it comes out. I would have to watch the video again as usually you can’t see anything. A bad actuator usually just clicks or does nothing.
Don’t run the blend doors actuators when they are not installed. They run to the stops in their location if you “test” them loose they can over run and will not work once installed. I worked for a manufacturer (not Dorman) and the most common “warranty” on the new part was because it was “tested” by the installer prior to being installed
Ram dealer told me on these trucks at about 140k miles the heater cores fail and have to be replaced. Its a dash out job and runs about $3000 if done by the dealership.There is one video on here shows how to avoid discharging the A/C when replacing the heater core. It is a well known problem and the dealers are aware of this issue. By the way well done video I subscribed ty.

Hello UncleMark I hope you see this comment. I followed this video and checked this actuator on my 2014 dodge ram and the needle moves up and down freely, switching from hot to cold.

My sons 2014 ram 1500 has no heat , i flushed the core a few weeks ago and after it had great heat, a couple weeks later he said his heat was gone again, so in the meantime his belt came off and it got hot and lost some coolant, after fixing that and topping off the coolant i checked the temp at the vents and it was 105f, now a week later no heat again, the hoses to the core are hot, so I'm guessing it's that little motor or the blend doors themselves..
@@sooperdan Womder if heater core is just plugging up with junk in the coolant? Or like you say, maybe now a blend door issue. I guess if you flushed core one more time and it’s giving heat, it’s a core & coolant issue. Keep us posted please, Dan.
I have a 2016 2500 with an all of a sudden heat problem. It has the same controls and when put on heat you feel warm air for about a second and then cold - both sides. Blend door actuator moves but I question if something is broken internally. How could flushing the core help-what would clog it in the first place?
Eventually they all plug up. Eventually as they get older, especially if lots of miles on them. This one has about 157,000 miles on it. As for clogging again, they want you to replace the bad coolant as well. The rad shops use to flush the whole system since the engine rad is probably clogging up as well. Does that make sense?
I thought the same thing ,bought the hose attachment with compressed air,flushed my heater core and I got heat back on drivers ,2013 ram all original actuators.
Hi folks , believe it or not on my 24L Dodge Caravan my heat was minimal. Recently while gassing up at WalMart i did the typical oil level check and also found my coolant very low.

@@waynemetcalf4254 They bought a new truck and only use this as a spare. Others I have heard of ended up needing a heater core. (Very labour intensive & expensive) Not flushable. I would make sure that is the issue before doing it though. I have heard $1500-$2500. The dash and steering wheel have to come out to access it.
Hello i have a 2013 dodge ram 1500 just did a complete flush and thermostat change i now get heat for 15 seconds and then it goes cold do u have any suggestions? Thanks for the video great tips
Could still be more junk in heater core. Could have come from anywhere since you did a complete flush. I would try flushing just the heater core again. (you are flushing it in reverse flow, right?) Probably not what you want to hear, Donnie? This is the only thing I can think of. Keep us posted.
Lok into it a bit more. Could be your heater core which is non flushable. (have a Dodge tech buddy & he says flush does nothing on these cores) Very expensive to have shop replace core. I would have a shop diagnose this issue if you go the shop route. (Not just tell them to replace a core, since it could be something else & they might just do what YOU SAY is the problem. (Let them test to make sure WHAT IS broken.
The no heat on drivers side? Probably plugged heater core. They are not flushable. Very expensive repair. (that is why I don't have a video on replacing it.) Dash has to come out etc. May get the truck back one day & do it. If I do, a video will follow.
The issue I'm having with my 08 ram 1500 is that my heater itself won't even turn on. Is it possible that it's the blower motor or that the switch itself is bad?
First thing I would check are fuses for the blower motor, Anthony. 2nd, with the fan on high, try tapping the blower motor with a hammer. If it starts up, probably a motor issue. These are the easy checks/fixes. You could also unplug the motor and measure for power with a test meter. Next it probably is time to got to a good shop and have them look into it. Lots of electrical things that could be the issue. Let me know how you make out.
@@unclemarksdiyauto Okay thank you for taking the time to read my comment and reply. The heater was working intermittently a day ago and I could bump the knob area with my hand and it would come back on but now that no longer works either. I will try what you recommend and let you know results.
Still doesn't fix my problem clod air is not going to drive side. Checked all motors and doors and work properly. Is it 2 doors on 1 motor for the one in the glove box?
@@unclemarksdiyauto blower works air circulation is not what it was . I did notice two things my recirculating door is broken and the climate control buttons have been replaced
@@robertschrader9799 Humm...Interesting. Of hand I can't give you any guidance. Getting inside to the circ doors is not very easy and I have heard to get the heater core replaced is a serval thousand dollar job. Dash comes out etc.
Thanks for the input Dennis. Tore the dash apart to find the other actuators which are behind that panel. Good to know that other actuator are hidden for other issues. (Dual climate zone has them somewhere, LOL)
Only if your thermostat is not working properly. If your engine cant get warm, there is not much heat to warm the cab. Does your temperature gauge sit where it always did once vehicle was warmed up? Those gauges are not that accurate, but if would be noticeably different. Like, if it always ran at half on gauge, bad thermostat might only run gauge at 1/4? Looks like these trucks all have same issue after they get a bit older.
@@unclemarksdiyauto thanks. I'm just wondering cause I'm not getting heat through my vents. It's only very little coming out I notice the heater core has one hose that's hot the other is warm. We flushed the heater core out once and it worked but after a week its back to no heat.
@@chrisruiz1215 Heater core probably plugged up again. Try flushing it again. Wonder how many miles/years old the coolant is? Not sure what the maintenance book says that should be changed.
That must be the one I could not find. I had no manual to go by with their locations. I actually saw the owner today and it is starting to get cold outside. Do you have access to a diagram as to location? Maybe email it to my channel?
I have had the same issue with my 2016 ram 3500. My issue started after I had the coolant flushed, but I thought it was a blendor actuator issue. I replaced all of the actuators and I am still have issues. I'm hoping I can find the fix soon.
I wonder chbowhunter23, if junk during the flush got trapped in the heater core? Could you try to back flush it with a garden hose? The couple Dodge Techs I have mentioned this to suggested the heater core as being half plugged as a possible issue.
@@unclemarksdiyautoI have figured out the issue yet. I'm in the St. Louis area and we just got about 8 inches of snow. I am planning on trying to flush the heater core next week when it warms up. I'm hoping that does the trick.
@@Jose-cd1mc I have not proved by working on it yet, but looks like a heater core flush could fix it. Do you have lots of miles on your truck? Coolant probably also needs a complete change/flush. Also a good time to replace thermostat. What does your owners manual say as to the coolant change interval? That is the plan, but since it will be a messy job, will get a shop to do it. If that does not cure it, possibly a new heater core. (Pretty big job) Of course, this might not be the issue.
If it is not this actuator, you might have a plugged heater core. (Can be flushed hopefully) Some have commented that the dealer wants about $3000 (not $300) to replace them. The whole dash and steering wheel has to come out. (If your vehicle is one of these trucks)
You keep pointing but Nada in the corner. Lol. My dash has a McDs coffee sticker on it right this minute in almost the same place. Must be a Canadian thing. Thanks Mark.
No heat before and after the change? Some have said that older or higher mileage vehicles have heater core issues. The new design of this core makes flushing it a waste of time and money.
7 yr old truck. Engine running at operating temp? Might be thermostat. All blend doors opening and closing all the way? Single or dual temp zones? Heater core could be getting plugged. Wonder what is recommended coolant life is? It could be breaking down and started to plug up core.
@@unclemarksdiyauto yes engine is up to temp, its the same heater as the truck you videod. When I turn the nob i hear the door in the dash. Im assuming its working. I have to see if the out hose is warm @ the heater core still, was 5 out a few mornings lol
@@jeffbm6880 Sometimes those doors can bind. Can you scan for codes? Even if no check engine light on. P0128. Thermostat rationality. (Thermostat stuck open)
Honesty, no! But seriously, is it warm on both sides of the vehicle? Do you have dual climate zones? (Drivers and passenger separate controls? Is your air compressor cycling on and off?
Still no answer. Talking to a couple Chrysler techs and they thinking heater core might be half plugged. It doesn’t make sense to me, but in my experience, sometimes it can be exactly what you know for sure it is not. (Hope that makes sense). I have not looked at it yet. About 3 or 4 other people have commented they have the exact same issue on the drivers side.
@@unclemarksdiyauto I'm getting responses of partially clogged heater core too. Doesn't make sense if passenger side is roasting hot tho. But im hearing more and more that could be the issue.
@@timothywolfe8792 weird, but maybe true. Not sure how core is situated in heater box. All the actuators seem to be working fine. Passenger side can be any temperature you want. Just drivers side is cold, or more correctly it blows the temperature of outside.
@@unclemarksdiyauto Thats where I'm at...also I did top off my antifreeze, it seemed to be down about half a gallon. Would that have an effect on heater core too?
Yep, that is what I suggested in the update card found at end of video. We did it! (It did not help in this case!) Thanks for the great suggestion though. Something not obvious is the problem.
@@rickr5223 could be all sorts of issues. Your going to have to do some testing. (Gonna need a wiring schematic) Is there power to the switches. Trace it back to TIPM. Also, is the grounds?
It could be a wire to or from the actuator or switch, or from switch to computer, or computer to actuator. You would need a wiring diagram to go further. maybe something is wrong with the switch. It may be time to let someone else take a look? (No shame in that) I don't have the wiring diagrams.
Any idea about the problem I have I own a 2013 express 2wd and my ac setup is exactly the same as in the video One knob for power or strength one for hot cold and one for what vents it blows out of Normally when I turn the knob all the way red and I turn the power or strength knob one notch to turn it on I have to press the power knob to make the little orange light come on so it actually blows hot air if the orange ac light doesn’t come on when it’s on heat it’ll blow mostly cold mildly warm air The orange light comes on automatically when my temperature is on cold but when it’s on the heat I press the “power or strength” knob and the orange light turns on and it goes from mildly warm to toasty When my truck is on the heat and I try to press the ac power knob the light doesn’t come on and it blows mildly cold air I’m a cheap ass and don’t wanna go to the dealership so any response would be much appreciated
Not so far. Was talking to 2 dodge Techs and they saying possibly heater core needs a flush. I don’t know how they route air through it, maybe it is possible if half the core was plugged and that half goes directly to the drivers side.I need to look at it again. (It is a friends truck) 1 thing for sure is everyone that has commented has the same drivers side cold! Never the passenger side! (So far)
@@unclemarksdiyauto ahh okay looks like ill have to pop the hood and check it out on one of my off days, thanks for the fast response tho! its a crazy coincidence that you made a ram 1500 ac problem video as soon as i have problems, my old man has followed your channel for over a year now.... he refers to you as the "classic car guru on youtube" or "old fashioned repair man" lol thank you for all you do ill teach my old man how to drop a sub and like we'll for sure support the channel going forward, i wasnt expecting such a fast response! really means a lot regardless if you actually can help with our problems or not! happy new years to ya!

We live in Canada with -40F winters. Did you know that in defrost mode, the AC turns on automatically? Even in AC mode, you temp is based on the temperature you have the control turned too. Try it. Turn your AC on and turn the temperate to as hot as it goes to. You will get hot!
@@lacasa102 Probably the heater core is plugged. Very expensive to do. They are not really flushable the way they are designed. Also, usually folks have added the wrong coolant at some point and it causes it to gel. You in the USA or Canada?
@ does your engine get warm? What is the temp gauge sitting at usually? Back to your question. The core plugs up and does not allow hot coolant to go through it, so you fan just blows the cold air. OR…it also could be a blend door actuator. Do you have dual temp controls or just one that controls both sides?
@@unclemarksdiyauto I can't see or feel any leaks but I haven't looked deep into it as far as the film there was some what does that mean And if it is heater core and I get it fixed will the antifreeze smell ever go away or should I just get rid of the truck
@@JojoPopo-s8j Antifreeze smell means antifreeze is leaking inside somewhere. May just be a very small leak. Just expect it to get worst and plan for it. Your antifreeze bottle under hood is still at proper level? Maybe it’s leaking at the firewall in the engine compartment? Or somewhere else and smell is being drawn in through air vents?

I grew up with those thick Chiltons manuals and say it bodes one Well to use common sense when trouble shooting. However I'd never buy any of these Over priced new cars. L😁L at over $80 K for a new pickup truck.
@@dougfredricks2017 New prices are nuts. I would not waist money on a new one. The dealers can’t even fix the new ones! Much better if we can keep our older vehicles going. Many are more reliable t(a the new ones.
Did you ever find out what was going on and why it was doing it? I’m dealing with the same problem
@@waynemetcalf4254 They bought a new truck and only use this as a spare. Others I have heard of ended up needing a heater core. (Very labour intensive & expensive) Not flushable. I would make sure that is the issue before doing it though. I have heard $1500-$2500. The dash and steering wheel have to come out to access it.
Hello i have a 2013 dodge ram 1500 just did a complete flush and thermostat change i now get heat for 15 seconds and then it goes cold do u have any suggestions? Thanks for the video great tips
Could still be more junk in heater core. Could have come from anywhere since you did a complete flush. I would try flushing just the heater core again. (you are flushing it in reverse flow, right?) Probably not what you want to hear, Donnie? This is the only thing I can think of. Keep us posted.
@@unclemarksdiyauto thanks for the reply i think u are exactly right. Great channel just subscribe
@@donnieporter7890 Let me know how it goes. You can also send a email. Address in my channel about page.
@@unclemarksdiyauto will do I appreciate you
Same issue please update if you come up with a solution
My little motor behind glove compartment works good, but still no heat.
Lok into it a bit more. Could be your heater core which is non flushable. (have a Dodge tech buddy & he says flush does nothing on these cores) Very expensive to have shop replace core. I would have a shop diagnose this issue if you go the shop route. (Not just tell them to replace a core, since it could be something else & they might just do what YOU SAY is the problem. (Let them test to make sure WHAT IS broken.
Okay I watch the video and the motor was working. How do you fix it though?
The no heat on drivers side? Probably plugged heater core. They are not flushable. Very expensive repair. (that is why I don't have a video on replacing it.) Dash has to come out etc. May get the truck back one day & do it. If I do, a video will follow.
The issue I'm having with my 08 ram 1500 is that my heater itself won't even turn on. Is it possible that it's the blower motor or that the switch itself is bad?
First thing I would check are fuses for the blower motor, Anthony. 2nd, with the fan on high, try tapping the blower motor with a hammer. If it starts up, probably a motor issue. These are the easy checks/fixes. You could also unplug the motor and measure for power with a test meter. Next it probably is time to got to a good shop and have them look into it. Lots of electrical things that could be the issue. Let me know how you make out.
@@unclemarksdiyauto Okay thank you for taking the time to read my comment and reply. The heater was working intermittently a day ago and I could bump the knob area with my hand and it would come back on but now that no longer works either. I will try what you recommend and let you know results.

@@unclemarksdiyauto p
@@francistamachaski3295 Got a question?
Still doesn't fix my problem clod air is not going to drive side. Checked all motors and doors and work properly. Is it 2 doors on 1 motor for the one in the glove box?
I still have not fixed this issue. Sounds like blend door might have broken in 2 pieces and drivers side is stuck. This is on the single zone system.
I have 2012 dodge ram 1500 air blows no hot no cold actuators seem fine but no heat or ac still blend doors work fine as well . Can you help ?
Does the fan run? If so, you say no circulation, Robert?
@@unclemarksdiyauto blower works air circulation is not what it was . I did notice two things my recirculating door is broken and the climate control buttons have been replaced
@@robertschrader9799 Humm...Interesting. Of hand I can't give you any guidance. Getting inside to the circ doors is not very easy and I have heard to get the heater core replaced is a serval thousand dollar job. Dash comes out etc.
@@unclemarksdiyauto I just find it odd that heat and ac stopped working at same time
@@robertschrader9799 I don't really understand how that is possible if there is airflow. Usually you have one or the other. Hope you figure it out!
I have 2013 with same problem you find the problem can you share how how fixed
I will post something if and when it is found. So far, I have not looked more into it.
Maybe a little better segway from simply removing the glove box in one shot which everyone can follow, to the entire dash ripped apart maybe.
Thanks for the input Dennis. Tore the dash apart to find the other actuators which are behind that panel. Good to know that other actuator are hidden for other issues. (Dual climate zone has them somewhere, LOL)
Does a thermostat make a difference to get better heat
Only if your thermostat is not working properly. If your engine cant get warm, there is not much heat to warm the cab. Does your temperature gauge sit where it always did once vehicle was warmed up? Those gauges are not that accurate, but if would be noticeably different. Like, if it always ran at half on gauge, bad thermostat might only run gauge at 1/4? Looks like these trucks all have same issue after they get a bit older.
@@unclemarksdiyauto thanks. I'm just wondering cause I'm not getting heat through my vents. It's only very little coming out I notice the heater core has one hose that's hot the other is warm. We flushed the heater core out once and it worked but after a week its back to no heat.
@@chrisruiz1215 Heater core probably plugged up again. Try flushing it again. Wonder how many miles/years old the coolant is? Not sure what the maintenance book says that should be changed.
You did not talk about the 4th actuator under the dashboard. How to replace it? Maybe in your next video. Thanks.
That must be the one I could not find. I had no manual to go by with their locations. I actually saw the owner today and it is starting to get cold outside. Do you have access to a diagram as to location? Maybe email it to my channel?
I have had the same issue with my 2016 ram 3500. My issue started after I had the coolant flushed, but I thought it was a blendor actuator issue. I replaced all of the actuators and I am still have issues. I'm hoping I can find the fix soon.
I wonder chbowhunter23, if junk during the flush got trapped in the heater core? Could you try to back flush it with a garden hose? The couple Dodge Techs I have mentioned this to suggested the heater core as being half plugged as a possible issue.
Did you find out what the issue was?
@@unclemarksdiyautoI have figured out the issue yet. I'm in the St. Louis area and we just got about 8 inches of snow. I am planning on trying to flush the heater core next week when it warms up. I'm hoping that does the trick.
@@Jose-cd1mc I have not proved by working on it yet, but looks like a heater core flush could fix it. Do you have lots of miles on your truck? Coolant probably also needs a complete change/flush. Also a good time to replace thermostat. What does your owners manual say as to the coolant change interval? That is the plan, but since it will be a messy job, will get a shop to do it. If that does not cure it, possibly a new heater core. (Pretty big job) Of course, this might not be the issue.
@@Jose-cd1mc I have not figured it out yet. I am planning on flushing the heater core next week. It seems like it could be the culprit.
I’ve got that same little tripod😃
I broke it and you can't tighten the newer ones enough for them to hold the camera. The stand stays put but the camera flops to the side.
FYI. Heater core issue! Bottom half (plugged half) of core goes to drivers side, top half to passenger side.
@@unclemarksdiyauto yes sir
very helpful thank you
If it is not this actuator, you might have a plugged heater core. (Can be flushed hopefully) Some have commented that the dealer wants about $3000 (not $300) to replace them. The whole dash and steering wheel has to come out. (If your vehicle is one of these trucks)
It’s a heater core half of its plug I’m doing mine right now try flushed it five times can’t get it to unplug so bought a new one
It might be a take the dash out to change the heater core? Let us know!
You keep pointing but Nada in the corner. Lol. My dash has a McDs coffee sticker on it right this minute in almost the same place. Must be a Canadian thing. Thanks Mark.
I see that! There should at least have the ram link there, thanks! Will look into it!
mines just cold i changed that blend door under glove box and no heat
No heat before and after the change? Some have said that older or higher mileage vehicles have heater core issues. The new design of this core makes flushing it a waste of time and money.
I agree
My 15 ram only has 65k miles and blows like 45 to 50 degrees. Ugh
7 yr old truck. Engine running at operating temp? Might be thermostat. All blend doors opening and closing all the way? Single or dual temp zones? Heater core could be getting plugged. Wonder what is recommended coolant life is? It could be breaking down and started to plug up core.
@@unclemarksdiyauto yes engine is up to temp, its the same heater as the truck you videod.
When I turn the nob i hear the door in the dash. Im assuming its working.
I have to see if the out hose is warm @ the heater core still, was 5 out a few mornings lol
@@jeffbm6880 Sometimes those doors can bind. Can you scan for codes? Even if no check engine light on. P0128. Thermostat rationality. (Thermostat stuck open)
Do you know why my ac just stoped blowing cold
Honesty, no! But seriously, is it warm on both sides of the vehicle? Do you have dual climate zones? (Drivers and passenger separate controls? Is your air compressor cycling on and off?
Where is the ac modeler in a 2018 dodge ram 1500
Do you mean motor? (Like blower / fan motor) Usually they are under the glove box.
What was the verdict after finding out actuator is working?
Still no answer. Talking to a couple Chrysler techs and they thinking heater core might be half plugged. It doesn’t make sense to me, but in my experience, sometimes it can be exactly what you know for sure it is not. (Hope that makes sense). I have not looked at it yet. About 3 or 4 other people have commented they have the exact same issue on the drivers side.
@@unclemarksdiyauto I'm getting responses of partially clogged heater core too. Doesn't make sense if passenger side is roasting hot tho. But im hearing more and more that could be the issue.
@@timothywolfe8792 weird, but maybe true. Not sure how core is situated in heater box. All the actuators seem to be working fine. Passenger side can be any temperature you want. Just drivers side is cold, or more correctly it blows the temperature of outside.
@@unclemarksdiyauto Thats where I'm at...also I did top off my antifreeze, it seemed to be down about half a gallon. Would that have an effect on heater core too?
@@timothywolfe8792 Hard to say. If it gets low enough, yes for sure. Question, with lower coolant level, was there still heat in passenger side?
My ram 2015 sport dont activate nothing, no blower and i cant activate with stereo too
Interesting. Have you checked fuses? Do you have power at the blower motor (with fan on high...you can use a test light for that)
try to flush the heater core.
Yep, that is what I suggested in the update card found at end of video. We did it! (It did not help in this case!) Thanks for the great suggestion though. Something not obvious is the problem.
Could of showed us how to take the cover off, really thought that was a important factor u skipped
There were some issues in editing. Here is another video with more detail. th-cam.com/video/sOAaPQ8msB8/w-d-xo.html
Mine does nothing has new blower motor and resistor
@@rickr5223 could be all sorts of issues. Your going to have to do some testing. (Gonna need a wiring schematic) Is there power to the switches. Trace it back to TIPM. Also, is the grounds?
@unclemarksdiyauto yeah it's very annoying
What would be the issue if the actuator finger is not moving. I’ve switched out the actuator already
It could be a wire to or from the actuator or switch, or from switch to computer, or computer to actuator. You would need a wiring diagram to go further. maybe something is wrong with the switch. It may be time to let someone else take a look? (No shame in that) I don't have the wiring diagrams.
Any idea about the problem I have
I own a 2013 express 2wd and my ac setup is exactly the same as in the video
One knob for power or strength one for hot cold and one for what vents it blows out of
Normally when I turn the knob all the way red and I turn the power or strength knob one notch to turn it on I have to press the power knob to make the little orange light come on so it actually blows hot air if the orange ac light doesn’t come on when it’s on heat it’ll blow mostly cold mildly warm air
The orange light comes on automatically when my temperature is on cold but when it’s on the heat I press the “power or strength” knob and the orange light turns on and it goes from mildly warm to toasty
When my truck is on the heat and I try to press the ac power knob the light doesn’t come on and it blows mildly cold air
I’m a cheap ass and don’t wanna go to the dealership so any response would be much appreciated
Not so far. Was talking to 2 dodge Techs and they saying possibly heater core needs a flush. I don’t know how they route air through it, maybe it is possible if half the core was plugged and that half goes directly to the drivers side.I need to look at it again. (It is a friends truck) 1 thing for sure is everyone that has commented has the same drivers side cold! Never the passenger side! (So far)
@@unclemarksdiyauto ahh okay looks like ill have to pop the hood and check it out on one of my off days, thanks for the fast response tho!

My truck never seems to get heated up, almost a 2 hour commute and I never get past my first quarter mark on temps
Try a higher temp thermostat. If it opens to soon you wont ever get full heat
Sounds like a stuck thermostat.
That truck is dirty as F'k
It’s is a working farm truck. Yep could use a clean up but I guess time is money on the farm.
You have the AC on
We live in Canada with -40F winters. Did you know that in defrost mode, the AC turns on automatically? Even in AC mode, you temp is based on the temperature you have the control turned too. Try it. Turn your AC on and turn the temperate to as hot as it goes to. You will get hot!
It would be nice, if you knew what it was that fixed the problem.
What exactly is your vehicle doing Linda?
I have ram 2004 no heating ☹️
Is only cold air but not heating 🥺could u give me any clue please?
@@lacasa102 Probably the heater core is plugged. Very expensive to do. They are not really flushable the way they are designed. Also, usually folks have added the wrong coolant at some point and it causes it to gel. You in the USA or Canada?
@@unclemarksdiyauto USA in los Ángeles buddy
@ does your engine get warm? What is the temp gauge sitting at usually? Back to your question. The core plugs up and does not allow hot coolant to go through it, so you fan just blows the cold air. OR…it also could be a blend door actuator. Do you have dual temp controls or just one that controls both sides?
@ ah..
Why does my cab smell like antifreeze
Heater core leaking? Are you getting a film on the inside of the windows yet?
@@unclemarksdiyauto I can't see or feel any leaks but I haven't looked deep into it
as far as the film there was some what does that mean
And if it is heater core and I get it fixed will the antifreeze smell ever go away or should I just get rid of the truck
@@JojoPopo-s8j Antifreeze smell means antifreeze is leaking inside somewhere. May just be a very small leak. Just expect it to get worst and plan for it. Your antifreeze bottle under hood is still at proper level? Maybe it’s leaking at the firewall in the engine compartment? Or somewhere else and smell is being drawn in through air vents?
@@JojoPopo-s8j Smell will go away after leak is fixed.
