Honda A/C Not Cooling and Engine Idle Fluctuations Troubleshooting

[@bernardaflores1720]

Great video, I learn something new today. You just forgot to mention to check those cabin filters first!

[@1McMurdoSilver]

You are the greatest Honda expert.

[@jngtruong]

What a great video! Your explanation and taking us along through the process really helps us understand the issue presented. I wished there is a shop in my area that has a YT channel so i can rest assure the attention and expertise they offer is just like yours.

[@BigDog50001]

Thank you, I appreciate the comment!

[@wdhewson]

Good show, in Phoenix the heat has probably never been on in that car!

[@imAgentR]

This has been helpful. I’m having similar issues after having the fans and the compressor replaced. Now the condenser is getting swapped. It’s all been done at the Honda dealership, save the fans. Car is 20 years old. If the issue persists after the condenser, I’m locking in on that actuator. Haven’t had any leaks or anything; just noticed it this summer. Usually when coming up to a stop the car goes into shutting off the motor, so I didn’t notice. 2003 Civic Hybrid

Dave when it’s 108 degrees out and 90+ in the shop 70 degrees would feel pretty cool. Man it’s hot out there by you. This has been a cool summer here on long island usually mid to high 70’s. Thanks for all the excellent troubleshooting tips. Hope all is well. 👍. Artie

Thanks Dave! Always great videos!

[@BigDog50001]

Thanks for the support Mike!

[@jvlax780]

Phenomenal diagnosis and explaining everything.

[@darink300zx]

My accord with auto ac does this sometimes. I just turn the temp all the way one way or the other and then back to where I want it and it works. Guess I should replace the blend door unit.

[@kroanosm617]

Best video by far. Every step covered and explained.

[@DavidCoffill]

Awesome job uncovering the problem! 😅

[@onyilosolo9350]

Thank you so much for this video. Tomorrow I will be visiting my AC technician to get same problem solved on my 06 civic. God bless u

[@idftsman8498]

OH Nice, lets see how to change that Actuator!

[@ernestbrooks399]

I have an 06 Civic with the exact problems.I suspected freon overfilled at first,then cked pressure sensor it was fine. Thank you for this video.

[@joedlf3618]

Great informative diagnostic vidio! Keep up the good work big Dog !

[@parkerbohnn]

I had the same problem what fixed it was a new battery and stop leak for the A/C system. It wasn't holding enough compression before.

[@proudtexan5513]

Great learning video and excellent diagnosis to find the real issue!!

[@stephenpatrick8068]

Look @ Big 🐕 take down that A/C issue, thorough diagnosis good job! I've noticed on my Honda Accord 2006 the blend doors are squeaking, good video got to check mine as well n

[@PaulNaylor3]

Great video and taking your time to understand all that is going on with the cooling system. I learned a lot.

[@kittsantos-ocampo6432]

Very Good! U r so awesome! Combining good science, technology, experience and intellect! More power to u! Exhibiting Great ethical competence Bravo! :)

[@justinreid8851]

Hey man love this channel for the content for my 08 Acura tos. Ever heard of an aux fan relay going bad?my car stays cool but I only hear the fans come on low at 205 degrees but never hear them on high. High is only with ac on? Wandering if a relay could be bad? Thanks for all your pointers

[@Cardoza0727]

This is great video man. Mine is doing the exact same thing as this. I changed the ac relay and fuse but nothing changed. At first when I run on the car on the highway AC runs great but as soon as come to a stop or crank up the AC speed it starts fluctuating and then starts blowing warm air. Going to change that blend door. Should I have it vacuumed and recharged too? TIA

[@manuel7958]

Hello I realty like the way you explain everything I have a question At what temperature the low and height speed on cooling fan should turn on Honda CR-V 2011

[@klilly2140]

I have a very similar issue to this. I have a 2011 Honda Pilot EXL with Dual Climate control. In the garage, I get 60-70 degrees on the passenger side, and 82+ degrees on the drivers side. If the car sits outside in the sun, the drivers side is over 100 degrees, while the passenger side is still around 60-70. If I leave the car idling for 10-20 mins, nothing seems to change. However, if I drive it down the highway, the drivers side returns back to 80 or so degrees about 10 miles in. Mostly I travel only short distances with this car so if I take it to the grocery store and it sits in the sun, the AC just blow heat the entire way home. Honda service center ran diagnostic on it and said there was nothing wrong with it, but was almost $500 just to conclude this. They checked the charge in the AC and said it was fine. Since then, I have taken to trying to diagnose this myself and replaced a few parts to rule them out (cheaper than diagnostic). I have installed new AC relays, a new blend door actuator on the drivers side. I then got a gauge to read the refrigerant level and it was in normal range (just as the service center concluded). I'm going to continue watching your videos but if you have any input, it would be greatly appreciated. ADDITIONAL INFO: The mechanic noted an odor from my vents and noted it seemed to be due to the evaporator being wet. He changed my cabin filter and sprayed citrus cleaner in the vents. Seems strange to me that additional steps were not taken at the time.

[@moisesguajardo5776]

hey BIG dog do you have a link to buy the same temperature probe you have for the vent check . I need one identical to yours

[@tonyjordan1320]

Its in the drop down menu-looks like Amazon has it....

[@VaderYouSeekVader]

Possible overcharge of refrigerant and intermittent blend door actuator malfunction.

[@waverider5751]

Typical in an older Civic.

[@tracycolorado]

You are the Big Dog 😊

[@lyndelld1]

I'm guessing mine is overcharged. The RPMs fluctuate when the cranked up all the way.

[@parkerbohnn]

A leak in the A/C system caused the problem and having a low A/C coolant makes it even worse. A new battery helps.

[@brenyz5013]

Very very well done video . Thank you so much !!!

[@alanw5812]

Thanks for the video, my civic fd have a problem of idle, hot idle is 700rpm' but every time A/C on, the idle up delay a little be, it drop to 500rpm,then back up ,but this car should be don't have IAC Valve, I think it control with Electronic Throttle Body only, do you know is this or the switch, how I find out ?

[@GeraldVonWolfgang]

Nice job on this ‼️

[@ST-xc3qw]

Great video I’ve had to replaced the blend door on my CR-V as well Luckily my issue was during winter and not during summer heat

[@jgeorges3061]

thanks Dave for an excellent /Awesome information really an eye opining. cheeeeeeers from CANADA,ONTARI

[@kroanosm617]

So what's the average cost for all the different jobs here. How much to change the blend door?

[@stefanhecht203]

Hello Dave, I have a Civic from 2011 fk2, IT makes the Same failure, Always AC on, off, on, off...... It is the right fill in the AC, ive Check it. Im interested you find this Problem on your Car. How much does this Driverside Motor cost? You make great Videos! 👍🙂✌️Greatthings from Germany ✌️

[@billwilliams2242]

Great video

[@DewannaMurry-nf1tt]

I have the same issue but I have a Ford Taurus.. just added freon and still goes from cool to warm . The compressor clicks on and off every second and engine idles down and almost dies.. and the check engine light stays on..

[@AWD_T]

Great diag 👍

[@Notthruhiking]

Thanks Dave

[@yailor7]

Awsome video!!

[@BigDog50001]

Thanks 👍!

[@lyndelld1]

Excellent

[@kevokiaa2312]

Having that issue here on a 2010 honda stream rsz,need some guy like you here to break stuff down... Question which of the honda model parts is compatible with the rsz if you know.. JAMAICAN watcher

[@parkerbohnn]

A new battery new spark plugs and stop leak for the A/C fixed the same Honda Civic 2010 EX-L. It was probably stop Leak that fixed it as it wouldn't hold compression.

[@rakeshmahadevan269]

Good Video

[@davidsmith5584]

I can’t imagine what it would be like if the blend door got stuck in full hot.

[@commander3065]

I've watched several of your videos. I need my 2011 CIVIC a/c serviced

[@joeyyung911]

What's that thing below the tach, by the mileage numbers? Is it an LED? I have an LED there for the iVTEC (R18). (So I know I'm in fuel economy mode).
