What if it is intermittent sometimes it's cold and another time it's not cool enough I ran a trouble test on the ac system and did not get a trouble code I saw the test on youtube where are you hold the rear defroster and the recirculating button then switch the car the number two position
On a 12 hour drive back from NC yesterday in my 2005 Honda Odyssey (best car I ever owned), it started blowing hot air on left and cool/cold air on the right. I'll trouble shoot later to start narrowing down the fix. A GREAT VIDEO at explaining the system operation !!!
Finally someone who fully understands the problem and the system and explains it clearly. I've always wondered why the left was warmer than the right. I have the climate control with dual doors. My issue ended up being low refrigerant.
Mine is doing this exact thing....ice cold on passenger side n just cold on driver side....mecanic only checked my ps vent...then i realized it was only my ds that felt warm...im gonna get it charged now
I'm in AZ. I was wondering since it's been so hot if that was a possible factor of my A/C acting up since my car is only 2yrs old. I have a 2017 Honda civic and its pretty upsetting that its happening so soon. Nevertheless, your video was some well needed clarification!
Do you ever see this problem because it's so darn hot the right side is boiling off all the refrigerant? i.e. it's 110F out and you see 60F coming out of the right and 90F out of the left and the heat load is too much for the A/C to cool off the car enough for the two to equalze? Meaning that neither of the problems you described is the issue. In my experience driving through hotter climates it seems like no small car has an AC strong enough to really cool things down in a reasonable amount of time.
Having same issue on my 2015 Acura RDX. Did research and I was about to order and replace the air blender actuator but one commenter said check the refrigerant first before ordering parts. Took it to a mechanic and he recharged it for $120. Lo and behold, AC now blows ice cold air on all vents. Thank God! Mechanic joked: if you get sick, don't blame me
Thank you, sir! You saved my remaining hairline 🤣You were absolutely correct, it was low on freon. My brother lend me his a/c gauge and purchased a small bottle of freon. Charged the a/c system in small quantities while monitoring the vents with a temperature gauge. I got it down to 42 degrees vs 75 degrees. The wife was starting to worry about her Ody not keeping her cool while driving in the desert heat that reaches 122 degrees 🥵Thanks for the video! 👍 Happy wife = Happy life 🤙
I just replaced the blend door actuator on the driver side. Still blowing hot on driver side. I will try recharging the Freon. I will give update in a bit. UPDATE: Yep, I just needed to recharge the Freon. Actuator didn't really need a replacement just needs to be regreased. Keeping the actuator as a spare.
In all my years doing a/c work, I never saw a low refrigerant charge cause temp variance in vents, esp. in Hondas. Instead, in Hondas, the mix door actuator goes bad. That's as common as you'll find. It's easy to replace too.

Nice video…..I was having this exact problem on my 2008 Honda CRV. In fact, the left side was about 23° warmer. I checked the Freon and it was right at 40 psi, but right now the ambient temperature is 110 in Vegas. I took the PSI up to 50 and now both sides blow nice and cold! I should’ve done this about two or three years ago when i noticed the driver side was warmer! Thanks again
Thank You for the clear explanation on why there is hot air blowing on the left side, and the number one reason being low refrigerant. My 2011 pilot has this exact issue. I will purchase a leak detector and go hunting my system stays charged for at least three weeks and then left side starts to get warm again.

I want to know who are the idiots that gave this a thumbs down? Great explanation … my accord is 16 years old. I had replaced both mixing doors a few years ago. But lately the left side is warmer than the right. I’ve seen driver side mixing door moving as I expect when I change the temperature. This video helped explain what else was going on perfectly. Will get a recharge tomorrow. Thanks!!
Sorry, I did not understand exactly what the problem is, as I speak Arabic and do not know English very well, I would like to ask you. Is the problem lack of gas or what?
That was an excellent video which explains the issue. I think I need to recharge my 2006 Honda Accord, which has never had any refrigerant added to the system! Thank you and best wishes.
Thanks Man! I had this issue with our 05 Accord Hybrid. I went through the factory auto-check procedure through the HVAC interface per the factory manual, and it said all was good. I took the car to Honda, told them that I thought it was low refrigerant. They verified that diagnosis, and evacuated and charged the system, after replacing the fill Schrader valves under warranty. The Schrader valves where a problem that caused the refrigerant to leak out after 15 years.. Honda still stood behind it.. What you said in this video was right on..
Thank you for the clear explanation. My driver side is blowing warmer but eventually it will get cool after driving for a bit, I am going to add refrigerant and see where im at.
Thanks for the huge help! 2017 Civic driver side is warm so it's probably due to a leak, and hopefully it's the AC Compressor leaking which would be covered by Honda's TSB extended warranty.
I don't know what year you have, but most new Hondas (2-3 years old) now use r1234yf refrigerant (thanks to the Government). Many manufacturers (including Honda) are having issues sealing these new systems. It will take some time until they get it perfect unfortunately.
Having this problem on my 2013 Odyssey. Air mix door motor is working just fine. On a humid 84 degree day, I’m getting 55 degree air out of the right side vents and 78 degree air out of the left. I’m also getting all the warm air out of the front windshield defog.
On our 2006 Accord with dual (left/right) blend door motors, the left one is definitely not good. If we ONLY use the standard cold/hot control (that operates both L & R) it works OK. But if anyone operates the L & R independently, the left motor loses its mind completely, sending nothing but hot air. The temp “fix” is to move the common L/R hot-cold buttons all the way HOT, back to all the way COLD, do that a few times and the left motor eventually syncs back. It’s a project for another day.
Early 10th Honda Civic models have a 10 year extended warranty for the condenser because it was poorly designed. I'm having the same problem shown on the video so I'm taking my car to the dealership this weekend to have the condenser checked out.
@@guitarhero9592 The dealership said the compressor was leaking and the condenser was fine. The dealership wanted to charge me around $1200 to replace the compressor and they would give me a free condenser with that (I just think they were trying to scam me). I added some refrigerant and my AC has been running fine since.

@@njo6480 the compressor is now covered for 10 years just like the condenser. But it’s not listed as a recall. If it’s been awhile, check back with them. My dealer put me on hold awhile then came back and confirmed. My Civic is a 2016 good luck
2004 Honda Accord EX-L. Exact same problem today. Took it in and explained what was happening, 80 degrees on the left vent, cool air on the right. They gave it back to me with a bill for $162 for oil, filter, rotate and air recharge. Still blows warm to hot air. I knew I was right when I told them the blend door was the problem and they wanted me to drive it for a week or about 150 miles so they could check for leaked dye. I told them a small leak has nothing to do with hot on one side cool on the other. ITS A BLEND DOOR PROBLEM and they are going to hear about it when I go back.
Always possible there is more than one issue, I see that a lot. Low refrigerant (most likely caused by a leak) or an air mix motor issue (if equipped with two air mix motors) can both cause poor cooling on the left side. Some models do not have two air mix motors (dual climate control) but most EX-L models do. If it does not have dual climate control it is most likely not an air mix motor/blend door issue due to only having one blend door on that design. A large enough refrigerant leak will cause poor cooling performance (starting with the left side) pretty quickly. Refrigerant restrictions and other electrical problems can also cause cooling performance issues too. Regardless, the shop should have been able to tell you the exact level of refrigerant they removed (i.e. was it low, overcharged or at the proper level?), they should have checked for leaks and advised on that and they should have checked operation of the air mix motor(s) and let you know the status of those also. Leaks, restrictions in the system and intermittent problems can all cause the shop to have difficulty finding the problem immediately but they should be communicating with you on what they have done. Thanks for the input!
Gonna try this tomorrow, should’ve tried it first. I replaced the blend door actuator thinking it was that since it was making noise but it wasn’t, so hopefully recharging the refrigerant solves the problem.
Thanks, @bigdog! This helps me understand and troubleshoot. My 2006 Accord had dual temperature controls and the passenger side sometimes blows the warmer air. The curious part is the if crank that side's temperature to lowest temp, it will send cool air through. Thus, I assume that by cranking it down the passenger side pulls more refrigerant. That would mean that the evap core is also split, I think. So I'll check the refrigerant first.
My 2014 jeep JKU is doing this exact thing. 44/57 on my passenger vents and 87 on my driver vents. Blend door and position selectors are working like normal.
Very descriptive man thank you very much I'm going to go try coolant right now regardless if adding the coolant works I know exactly what I have to do so I appreciate you so much.
Thanks for the info........my dealer has been telling me for the past 2 years that this is how the 2018 accords were built!!! When I Have the air on 65, there is hot air coming out of driver side vent, dealers solution was to always use the air on low because then it finally starts blowing out cold air
Thanks for the info. My 2018 accord is blowing warm on the left side. It has enough refrigerant. I'm trying to see what component do I need to replace to fix the AC from blowing warm on the left side back to blowing cold. What do I need to replace?
Actuator door works and I have fresh refrigerant in my dual setting pilot. Still having the problem of cold air on passenger side and less cold on driver side.
so what if it was on the right passenger side and switched to the left driver side after I swapped a new cabin filter (2012 Acura TL). i pulled the motors thinking one was bad but theyre not. Also, the cabin filter was full of tree leaves and sticks so i was wondering 1. HTF and 2. could a stick be stuck in there somewhere holding the blend door open on one side ? 3. Why would the heat swap from the right to the left just changing the cabin filter?
Thanks for the information. I took the van to dealership. They replaced the motors and adjusted the freon level. The driver's side still blows warmer at idle but cooler when can is is motion. What could be the cause? The condenser fan? Thanks.
I have a 2006 Honda Accord EX that has this problem. The door blend actuator on the driver's side was replaced since it was broken. The problem was still there so I recharged my system with freon (19 oz.) and still no success. I now found out that the recirculation actuator on the driver's side is also not moving its arm at all so I ordered a new one. I tried moving the blend door manually but the problem still persists. This car has 3 actuators under the dash and the 3rd one (the mode actuator) appears to be working well. However, I think I've found 2 problems with the system recharge. The first is that both valve cores are bad as they are slowly leaking and second, the ac manifold readings are off from what I think is considered normal. The ambient temp here is about 86 °F. With engine off: Low side --> ~105 psi and High side - - > ~105 psi. With engine on and ac on: Low side --> ~20 psi and High side ---> ~65 psi. I added 19 oz. of freon as that's what the service manual calls for. Should I replace the valve cores and add more freon to try to raise the pressures?
my 2010 cr-v is blowing the opposite its cold on the driver side and hot on the passenger side. I dont have heat on the driver side. I know the door motor is not working right if it goes to defrost it wont to back to other blower positions, feet, head, or both. till it MAGICALY moves again.
Im experiencing this now with our 06 Odyssey with 232K miles. Drivers side is hot and passenger out. But when I turned the ac lower to 58 degrees both are cold. Dunno why?
i have this issue right now on my 2010 civic, the passenger side vent (just the one on the right) is cold and the driver and middle vents are warm. I have checked the AC relay (OK), checked the temp ix door (its working), performed a hvac self test and no lights flash, checked r-gas with the fill can kits and its in the blue (filled). Not sure what else it can be. I noticed first thing in the am when it is a bit cool outside, all vents are ok and then within 10 to 15 mins same issue happens. Any help would be awesome!
Appreciate it! My AC router has actually been draining my battery and what finally tipped us off to it was a combination of a lovely Polish man posting a video about it, and my AC pulling this exact stunt and blowing me in the face with heat while my passenger gets all the cold. Now I just have to figure out which one it is…
@@Mike321795 check your door actuators!!! This Honda CRV model will turn into a 2 ton door stop/paper weight if your door and or window actuators blow and won’t put power through to any of the above! Also check your AC seals!! I have not done this but my Honda turned into a paper weight and we had to smash in the left window, which also took 3-4 tries with actual tools!!
Okay, so I really appreciate this video. I'm having a problem with my vents. In my 2005 Honda Pilot, facing the dash (like you do) the far left (driver's side left) vent has cool air, while nothing is coming out of the other dash vents. Is this low refrigerant, or a defective part somewhere? Thank you, Big Dog50001 Automotive.
Mine has a small leak on a high side coupling and the high side service port. The caps need to be TIGHT on these ports. The o-ring in the cap is the primary seal NOT the shrader valve unlike in a car or bicycle tire.
Correct, technically the cap is considered the primary seal on AC systems but the valve should not leak when cap is removed. The Schrader valve should be replaced if they leak.
So mine had all blend doors replaced and freon fully charged however mine still blows warmer on driver side and cold on pass side. Could the expansion valve be half way stuck or not functioning properly and be causing this issue. Thanks
This one video assured me that I must subscribe.....great job with the video...informative, simple and yet effective (liked, comment, subscribed and shared) 👍🏿
Where you have Left and Right, which is the driver's side vs. passenger's side? This always confuses me on cars. Is it looking at it from the driver's perspective (sitting in driver's seat) or the mechanic's perspective (standing in front of engine compartment).
I have an 05 Honda Accord where if the AC is on, it will only blow cold out of the right side. However if the heat is on oh, it will only blow the heat from the right side. It just seems to blow whatever temperature is coming through the vents out the left. I.e. if it's cold outside I'm getting cold air on the left, if it's hot outside I'm getting hot air coming through the left. Would you say that it could be the blower door for the left side?
This has been an issue with my 2012 Nissan Sentra… just took it to the shop 2 weeks ago & they added Freon .. it was working great for first week.. now week 3 and it’s doing the same thing.. I know just matter of time until they all blow hot..that what happened last time
I appreciate the video. My issue is that when you are idling on my honda odyssey it blows warm air on the drivers side while the passenger stays cool. Now when you start to drive then the drivers side begins again to blow cool air once more. What can this be?
@@BigDog50001 Thanks for the reply. I did see both fans running while the car was idling if that helps. When i put the a/c low pressure reader on it shows to be in the green which indicates to me that freon is ok.
My passenger side started blowing cold air when the heat was on, drivers side was blowing heat like it should. Replaced the passenger side blend door actuator and then it’s reversed. With the AC on I get cold air like I’d expect from the drivers side but now hot air from the passenger side. Any help?
HELP PLEASE. I own a 2010 Acura TL 105,790 miles. I HAVE HAD 4 EVAC/Freon replacements done In the last 4-6 wks & replaced driver side acuator. ITS STILL HOT on the left/drivers side😡😡😡😡😡 3 shops say there is an obstruction BUT NO ONE HAS FOUND IT!!!!! I’ve paid almost $1k trying to get it fixed. What do you suggest?
I have a Honda HRV 2016 and the left vent does not blow out any air at all. Just had the filters changed too and issue was not present before. Could it be an issue with the installation or a sensor issue. Theh want to charge me $125 just for diagnostics even though the issue was not present before I took it for the filter change.
Hi, I need to get some advice regarding my 2017 Honda Civic. On June 6, 2022 I took my vehicle to a Honda dealership because it was blowing hot air on the driver's side when the A/C was on. They replaced the condenser, O rings and dye due to a leak. I'm having the exact same problem again. Could a new condenser fail within 4 months? I'm seeing that it takes 3-5 hours to replace a condenser, Is that correct because the dealership did the work in 1 1/2 hours? How would I know if the condenser was actually replaced vs patching the leak since it's problematic again? Thank you.
There are definitely issues with leaks at/near the condensers on newer Civics. The techs at the dealerships have replaced so many that they can typically do it much faster than the book time now. At 4 months, the dealer should at least look at it for you due to the same complaint (however there are many things that can cause this issue besides leaks at condenser).
I'm having this same issue driver side is warm at 34 setting but if I turn it down. To 12 then it's cold like passenger side whats going on any help please lol I don't think low fridgerant would do that because all would be warm
Hey @bigdog50001, I’m having the same issue so I checked the Freon & added accordingly but that didn’t fix it. I then checked the blend door actuator and that is working fine, I pulled the actuator off to rotate the gear by hand to see if I can feel the door open & close and that was ok. Next step I had the compressor changed & that didn’t fix the issue either. While driving on the highway the air is much cooler but dead stop it’s back to warm on driver side cool on passenger side. Do you think maybe it could be the TXV or the evaporator?
my 2008 accord i usually set temperature at 20 c which is not too cold nor hot for me ,now i notice even if i bump up the temperature to 25 i still get the cold air at 26 i feel the warm air , ur explanation doesn't seem to be fitting in my problem, am i correct:? any expert opinion of urs pls
Liked 👍 questions however, in my wife's 09 4 door accord, it's not warm at all on the left side. The ac pump is turned off. The heat is on. What might you say the problem is then?
If it just happened after work was done, then I would double check work. Some things I would look at for no heat: low coolant level, air in cooling system, proper operation of engine coolant temp (ECT) sensors (ECT 1 and ECT 2), thermostat issues, air mix motor issues (especially if it is a dual climate control system), recirculation control motor issues.
Wondering this too. There is still air being blown out, but it's outside air temperature, or close to. Our car has dual control, reckon I will see if it's charged with refrigerant and go from there.
Very informative video!but in my honda civic touring 2016 im experiencing left side means drivers side vents cold and right side not cold as left vents.

Thank you for the clear explanation. My driver side is blowing warmer but eventually it will get cool after driving for a bit, I am going to add refrigerant and see where im at.
Make sure to refill with a manifold gauge set so you dont overfill and blow up your A/C system.
Thanks for the huge help! 2017 Civic driver side is warm so it's probably due to a leak, and hopefully it's the AC Compressor leaking which would be covered by Honda's TSB extended warranty.
did you find the reason?
did you find the reason ?
Thank you, I was able to recharge the ac and that worked.
Thanks i had the same problem it was low on freeon now its working fine!
thank you...started today. 12000 miles. Used to love Honda. rethinking it now.
I don't know what year you have, but most new Hondas (2-3 years old) now use r1234yf refrigerant (thanks to the Government). Many manufacturers (including Honda) are having issues sealing these new systems. It will take some time until they get it perfect unfortunately.
This video helped me to understand next things to do since my 2006 odyssey vent doors are working fine. Oreilly guy helped me to fill more Refringent
High pressure inside my system (i.e. freon excess) caused my problem. I had some drained, all good now

Having this problem on my 2013 Odyssey. Air mix door motor is working just fine. On a humid 84 degree day, I’m getting 55 degree air out of the right side vents and 78 degree air out of the left. I’m also getting all the warm air out of the front windshield defog.
On our 2006 Accord with dual (left/right) blend door motors, the left one is definitely not good.
If we ONLY use the standard cold/hot control (that operates both L & R) it works OK. But if anyone operates the L & R independently, the left motor loses its mind completely, sending nothing but hot air.
The temp “fix” is to move the common L/R hot-cold buttons all the way HOT, back to all the way COLD, do that a few times and the left motor eventually syncs back.
It’s a project for another day.
This is happening right now in my Acura TL 4G. Preciate it.
Early 10th Honda Civic models have a 10 year extended warranty for the condenser because it was poorly designed.
I'm having the same problem shown on the video so I'm taking my car to the dealership this weekend to have the condenser checked out.
👍
Did the Condenser fix the problem?
@@guitarhero9592 The dealership said the compressor was leaking and the condenser was fine. The dealership wanted to charge me around $1200 to replace the compressor and they would give me a free condenser with that (I just think they were trying to scam me). I added some refrigerant and my AC has been running fine since.
@@njo6480 Check Top Class Actions search Honda class action alleges civic a/c defect page 87 Anthony Alvaro post dated May 19 2023 states Honda now covers compressor with campaign and service bulletin. Hope this is helpful. Good luck.
@@njo6480 the compressor is now covered for 10 years just like the condenser. But it’s not listed as a recall. If it’s been awhile, check back with them. My dealer put me on hold awhile then came back and confirmed. My Civic is a 2016 good luck
Yo this is the best explanation I’ve seen regarding this matter. Thank you very much.
Glad it was helpful!
2004 Honda Accord EX-L. Exact same problem today. Took it in and explained what was happening, 80 degrees on the left vent, cool air on the right. They gave it back to me with a bill for $162 for oil, filter, rotate and air recharge. Still blows warm to hot air. I knew I was right when I told them the blend door was the problem and they wanted me to drive it for a week or about 150 miles so they could check for leaked dye. I told them a small leak has nothing to do with hot on one side cool on the other. ITS A BLEND DOOR PROBLEM and they are going to hear about it when I go back.
Always possible there is more than one issue, I see that a lot. Low refrigerant (most likely caused by a leak) or an air mix motor issue (if equipped with two air mix motors) can both cause poor cooling on the left side. Some models do not have two air mix motors (dual climate control) but most EX-L models do. If it does not have dual climate control it is most likely not an air mix motor/blend door issue due to only having one blend door on that design. A large enough refrigerant leak will cause poor cooling performance (starting with the left side) pretty quickly. Refrigerant restrictions and other electrical problems can also cause cooling performance issues too.
Regardless, the shop should have been able to tell you the exact level of refrigerant they removed (i.e. was it low, overcharged or at the proper level?), they should have checked for leaks and advised on that and they should have checked operation of the air mix motor(s) and let you know the status of those also. Leaks, restrictions in the system and intermittent problems can all cause the shop to have difficulty finding the problem immediately but they should be communicating with you on what they have done. Thanks for the input!
Thank you sir I love you and so does my mom shes cant hardly breathe and has copd
Thanks! You sir explained the nature of the issue so it made sense. Transfer of knowledge successful!
Thank you for the support, I appreciate it!
I enjoy the white board of knowledge. It's easy to visualize the system when it's right there in front of you. :)
Appreciate the comment Wyatt!
Gonna try this tomorrow, should’ve tried it first. I replaced the blend door actuator thinking it was that since it was making noise but it wasn’t, so hopefully recharging the refrigerant solves the problem.
👍
Thanks, @bigdog! This helps me understand and troubleshoot. My 2006 Accord had dual temperature controls and the passenger side sometimes blows the warmer air. The curious part is the if crank that side's temperature to lowest temp, it will send cool air through. Thus, I assume that by cranking it down the passenger side pulls more refrigerant. That would mean that the evap core is also split, I think. So I'll check the refrigerant first.
hey! were you able to fix it?
No that's not how it works. Most likely your problem is a bad passenger blend door actuator
@@mehedimostofa627 it wasn't the refrigerant.
@@gfriedman99 I'll check this. Thank you.
@@ManuelPumaradawas it the actuator?
My 2014 jeep JKU is doing this exact thing. 44/57 on my passenger vents and 87 on my driver vents. Blend door and position selectors are working like normal.
Very descriptive man thank you very much I'm going to go try coolant right now regardless if adding the coolant works I know exactly what I have to do so I appreciate you so much.
Thanks Big Dog, this is just what I needed.
Great video. In my E bent throwing some air even AC and fans are in off position. What can be the fix?! Ty
Very helpful but next time add where to get coolant if I can add coolant myself or what here?
Having this issue now in my 2012 Honda accord se. I'm getting the refrigerant replaced now, crossing my fingers.
Thanks for the info........my dealer has been telling me for the past 2 years that this is how the 2018 accords were built!!! When I Have the air on 65, there is hot air coming out of driver side vent, dealers solution was to always use the air on low because then it finally starts blowing out cold air
Thanks for the comment!
Thanks for the info. My 2018 accord is blowing warm on the left side. It has enough refrigerant. I'm trying to see what component do I need to replace to fix the AC from blowing warm on the left side back to blowing cold. What do I need to replace?
thank you very much for explaining us the video.
Actuator door works and I have fresh refrigerant in my dual setting pilot. Still having the problem of cold air on passenger side and less cold on driver side.
Is refrigerant the same as freon?
If I cannot replace myself ,is this expensive replace or fix if I were to
Bring it to a Machanic?
so what if it was on the right passenger side and switched to the left driver side after I swapped a new cabin filter (2012 Acura TL). i pulled the motors thinking one was bad but theyre not. Also, the cabin filter was full of tree leaves and sticks so i was wondering 1. HTF and 2. could a stick be stuck in there somewhere holding the blend door open on one side ? 3. Why would the heat swap from the right to the left just changing the cabin filter?
Hi thanks for the video.
I have the same problem but on the opposite sides. I hope is the same problem
👍
EXCELLENT DETAILED VIDEO!!! Thank you! I subscribed. Continue success!
Cold on right hot on left, After about 30 45 minutes left side is cold? but your explanation makes a lot of sense.
👍
Thanks for the information. I took the van to dealership. They replaced the motors and adjusted the freon level. The driver's side still blows warmer at idle but cooler when can is is motion. What could be the cause? The condenser fan? Thanks.
I have a 2006 Honda Accord EX that has this problem. The door blend actuator on the driver's side was replaced since it was broken. The problem was still there so I recharged my system with freon (19 oz.) and still no success. I now found out that the recirculation actuator on the driver's side is also not moving its arm at all so I ordered a new one. I tried moving the blend door manually but the problem still persists. This car has 3 actuators under the dash and the 3rd one (the mode actuator) appears to be working well. However, I think I've found 2 problems with the system recharge. The first is that both valve cores are bad as they are slowly leaking and second, the ac manifold readings are off from what I think is considered normal. The ambient temp here is about 86 °F. With engine off: Low side --> ~105 psi and High side - - > ~105 psi. With engine on and ac on: Low side --> ~20 psi and High side ---> ~65 psi. I added 19 oz. of freon as that's what the service manual calls for. Should I replace the valve cores and add more freon to try to raise the pressures?
my 2010 cr-v is blowing the opposite its cold on the driver side and hot on the passenger side. I dont have heat on the driver side. I know the door motor is not working right if it goes to defrost it wont to back to other blower positions, feet, head, or both. till it MAGICALY moves again.
Im experiencing this now with our 06 Odyssey with 232K miles. Drivers side is hot and passenger out. But when I turned the ac lower to 58 degrees both are cold. Dunno why?
I saw instructions on how to reprogram the blend actuator door and it worked ! Now 4 weeks later same issue but I forgot to save it. Any links ?
Same question!
i have this issue right now on my 2010 civic, the passenger side vent (just the one on the right) is cold and the driver and middle vents are warm. I have checked the AC relay (OK), checked the temp ix door (its working), performed a hvac self test and no lights flash, checked r-gas with the fill can kits and its in the blue (filled). Not sure what else it can be. I noticed first thing in the am when it is a bit cool outside, all vents are ok and then within 10 to 15 mins same issue happens. Any help would be awesome!
Hey Neil
have you sorted out the issue
Did you figure it out yet?
Clear and precise info, thank you!
Could this happen to an Volvo xc90 2007? I have the same simtoms.
What type of coolant does the AC require for a 2014 Honda CR-V require?
Appreciate it! My AC router has actually been draining my battery and what finally tipped us off to it was a combination of a lovely Polish man posting a video about it, and my AC pulling this exact stunt and blowing me in the face with heat while my passenger gets all the cold. Now I just have to figure out which one it is…
Did you ever find out what was the issue my battery draining too
@@Mike321795 check your door actuators!!! This Honda CRV model will turn into a 2 ton door stop/paper weight if your door and or window actuators blow and won’t put power through to any of the above!
Also check your AC seals!! I have not done this but my Honda turned into a paper weight and we had to smash in the left window, which also took 3-4 tries with actual tools!!
Okay, so I really appreciate this video. I'm having a problem with my vents. In my 2005 Honda Pilot, facing the dash (like you do) the far left (driver's side left) vent has cool air, while nothing is coming out of the other dash vents. Is this low refrigerant, or a defective part somewhere? Thank you, Big Dog50001 Automotive.
Very instructive! Thank you
I appreciate the comment, thanks!
Mine has a small leak on a high side coupling and the high side service port. The caps need to be TIGHT on these ports. The o-ring in the cap is the primary seal NOT the shrader valve unlike in a car or bicycle tire.
Correct, technically the cap is considered the primary seal on AC systems but the valve should not leak when cap is removed. The Schrader valve should be replaced if they leak.
So mine had all blend doors replaced and freon fully charged however mine still blows warmer on driver side and cold on pass side. Could the expansion valve be half way stuck or not functioning properly and be causing this issue. Thanks
This one video assured me that I must subscribe.....great job with the video...informative, simple and yet effective (liked, comment, subscribed and shared) 👍🏿
Thanks and welcome!
if ac is off, just fan on. and driver’s side is warm and passenger side is cool air, would this be the result of bad blend actuator?
If it is a dual climate control system then yes one of the actuators could be bad. Could also be a coolant system problem too.
Mine does do that but it has a enough Freon what else could be the problem
Same thing happened on my wife's Toyota. Sienna.
Mine read low on freon. I added to it. I also changed the blend door actuator. It's still doing blowing hot air on the driver side. Bummed out.
Where you have Left and Right, which is the driver's side vs. passenger's side? This always confuses me on cars. Is it looking at it from the driver's perspective (sitting in driver's seat) or the mechanic's perspective (standing in front of engine compartment).
always refer as "Driver side" or "Passenger side"... the diagram is from inside the vehicle if that helps
I fix my compressor in a 2010 Honda Accord it cooling but not cold. It's Gass up also
I have an 05 Honda Accord where if the AC is on, it will only blow cold out of the right side. However if the heat is on oh, it will only blow the heat from the right side. It just seems to blow whatever temperature is coming through the vents out the left. I.e. if it's cold outside I'm getting cold air on the left, if it's hot outside I'm getting hot air coming through the left. Would you say that it could be the blower door for the left side?
This has been an issue with my 2012 Nissan Sentra… just took it to the shop 2 weeks ago & they added Freon .. it was working great for first week.. now week 3 and it’s doing the same thing.. I know just matter of time until they all blow hot..that what happened last time
I appreciate the video. My issue is that when you are idling on my honda odyssey it blows warm air on the drivers side while the passenger stays cool. Now when you start to drive then the drivers side begins again to blow cool air once more. What can this be?
Without being able to see the vehicle, one or both cooling fans not working properly or low refrigerant are what come to mind initially.
@@BigDog50001 Thanks for the reply. I did see both fans running while the car was idling if that helps. When i put the a/c low pressure reader on it shows to be in the green which indicates to me that freon is ok.
My gauge says it's not a freon problem. Guess i gotta find out of its the core or door
My passenger side started blowing cold air when the heat was on, drivers side was blowing heat like it should.
Replaced the passenger side blend door actuator and then it’s reversed. With the AC on I get cold air like I’d expect from the drivers side but now hot air from the passenger side. Any help?
what if there is cold air on the left side and hot air on the right?
from what he says, I'd think if you have dual zone AC, the right air mix door would be the issue
Man thanks a lot you save me time and money keep it up is a very helpful video
Glad it helped!
Great video 👍, can you make another video how to add the refrigerant to fix this problem.
Thanks for the comment, I will see what i can do!
HELP PLEASE. I own a 2010 Acura TL 105,790 miles.
I HAVE HAD 4 EVAC/Freon replacements done In the last 4-6 wks & replaced driver side acuator. ITS STILL HOT on the left/drivers side😡😡😡😡😡
3 shops say there is an obstruction BUT NO ONE HAS FOUND IT!!!!! I’ve paid almost $1k trying to get it fixed. What do you suggest?
I have a Honda HRV 2016 and the left vent does not blow out any air at all. Just had the filters changed too and issue was not present before. Could it be an issue with the installation or a sensor issue. Theh want to charge me $125 just for diagnostics even though the issue was not present before I took it for the filter change.
Hi, I need to get some advice regarding my 2017 Honda Civic. On June 6, 2022 I took my vehicle to a Honda dealership because it was blowing hot air on the driver's side when the A/C was on. They replaced the condenser, O rings and dye due to a leak. I'm having the exact same problem again. Could a new condenser fail within 4 months? I'm seeing that it takes 3-5 hours to replace a condenser, Is that correct because the dealership did the work in 1 1/2 hours? How would I know if the condenser was actually replaced vs patching the leak since it's problematic again? Thank you.
There are definitely issues with leaks at/near the condensers on newer Civics. The techs at the dealerships have replaced so many that they can typically do it much faster than the book time now. At 4 months, the dealer should at least look at it for you due to the same complaint (however there are many things that can cause this issue besides leaks at condenser).
I'm having this same issue driver side is warm at 34 setting but if I turn it down. To 12 then it's cold like passenger side whats going on any help please lol I don't think low fridgerant would do that because all would be warm
Hey @bigdog50001, I’m having the same issue so I checked the Freon & added accordingly but that didn’t fix it. I then checked the blend door actuator and that is working fine, I pulled the actuator off to rotate the gear by hand to see if I can feel the door open & close and that was ok. Next step I had the compressor changed & that didn’t fix the issue either. While driving on the highway the air is much cooler but dead stop it’s back to warm on driver side cool on passenger side. Do you think maybe it could be the TXV or the evaporator?
Update. It ended being the expansion valve that wasn’t letting the refrigerant flow correctly throughout the evaporator
They are solutions to fix this problem ?
my 2008 accord i usually set temperature at 20 c which is not too cold nor hot for me ,now i notice even if i bump up the temperature to 25 i still get the cold air at 26 i feel the warm air , ur explanation doesn't seem to be fitting in my problem, am i correct:? any expert opinion of urs pls
Liked 👍 questions however, in my wife's 09 4 door accord, it's not warm at all on the left side. The ac pump is turned off. The heat is on.
What might you say the problem is then?
If it just happened after work was done, then I would double check work. Some things I would look at for no heat: low coolant level, air in cooling system, proper operation of engine coolant temp (ECT) sensors (ECT 1 and ECT 2), thermostat issues, air mix motor issues (especially if it is a dual climate control system), recirculation control motor issues.
If mix door on left is not working, will air flow be restricted?
Wondering this too. There is still air being blown out, but it's outside air temperature, or close to.
Our car has dual control, reckon I will see if it's charged with refrigerant and go from there.
am having this issue in my azera 2014 .. do I have to change the evaporator! or refill refrigerant.?
Very informative video!but in my honda civic touring 2016 im experiencing left side means drivers side vents cold and right side not cold as left vents.
