- Опубліковано 26 сер 2024
- After finishing the Air conditioning was filled with gas, the AC did not work. I had to reset the AC and clear existing error codes. This video shows the steps. I have also including a little information on OBD2 logs and hidden service menu on the Comand console.

THIS was for me, a LIFE-SAVER. My local Mercedes Benz Agency didn't even have the personal integrity to admit that they had NO IDEA about having to reset the aircon. Cost me HUGE money and suffering. Even the local Auto-Aircon. people [who the Mercedes Agents support] had no idea - tried 3 times, but couldn't figure it out. But that's NORMAL here in Vredendal, Western Cape, South Africa. SO, in desperation, I found YOU - and THAT simply WORKED, right away. THANK you SOOO MUCH.
Thank you for this video! It saved me from compressor replacement.
Your expertise just fixed my problem. Now I can enjoy my A/C. I just had the system charged and needed to reset the codes just like you said. Thank you sir!!
Assalam mualaikum, I have done exactly what you had shown & it works fantastically, it work continuously without stopping for 5 hrs after resetting it this morning. Before it work intermittently & at time the blower stopped. This was after I changed for a new blower. Probably the old blower is ok it is just the controller switch. Thanks a lot, may Allah bless you & give good tiding to you. JazakaAllah khair.
Today I decided to re charge my 2003 S430, I connected the quick connect and it shows that I am at middle of green, I added a little bit and it was to quick it goes almost to full, I knew something was not right. My A/c still not blowing cold air. The clutch wasn't engaging and "EC light still on". After I saw your video, I decided to get the codes and delete them as you showed on your video. The light on EC turned off, set the A/C on full, reconnect R134a quick connect and finally got the correct reading, started the process to recharge and now My A/C is back to normal blowing really cold air! Thank you so much for this video. You saved me dollars!!!
ritome2014 You are welcome. Thank you for taking time to share your experience.
😅😅😅😅 everybody listen to this guy I tried to do the first time then my air works I couldn't get it to turn on thank you so much wish I could send you some money🎉🎉🎉
This worked for me immediately and I’m so glad cause it’s 80 degrees here. I’m in South Carolina visiting family.
Thanks for sharing. With this video, I was able to reset the AC and add refrigirant to my 2004 S430. My AC works again.
I had a cooling fan issue (w220 s430) and could'nt get the blades humming until You game to help me with this RESET-thing!
Thank You so much for sharing the knowledge!!
Thank you for sharing your knowledge. Please ignore the morons criticizing your accent. They are miserable people that arent thankful for the help you provide. God Bless you!
YOU GOT TO BE KIDDING YOU HAVE NO IDEA HOW MUCH YOU HELP PEOPLE OH MY GOD THANK YOU
Thank you for making this video. If it wasn't so difficult to get proper internet connection where I am at right now I would've figured out this ac a while back. So instead of looking for videos, which takes too long to load, I tried finding all sorts of reading materials without success. Thanks again
Great video!! It saved me hundreds!!! of dollars!!. My ac blower went out for quite a while before I replaced it. However, I still ran the ac unit to get a little draft cooling. The control unit probably sensed the lack of heat transfer and stopped the unit with an error. Works like a charm now!! 🤗🙏
I have the S430 2003. You may be low on refrigerant. With low refrigerant the compressor works
harder and makes the little bit of refrigerant much colder to try and cool the car. However this will cause the unit to freeze up and trip the unit off. Hope this helps!
Thank you so much... You can't imagine how this helped me a lot... It's 55 C degrees here... Many thanks
Confirmed: This works on my 2002 Mercedes-Benz S55 AMG. Interesting that we need to reset the codes in order for the A/C to work the cool air again, particularly after refilling the condenser etc. I guess I should realize the by now this car has so many fail-safes to avoid major breakdowns yet it still finds its way to being a major headache!
On a positive note, this is more convenient than needing to hook up my scan device (iCarsoft).
Thanks for the vid.
Thanks for the video.It saved me a trip to the Dealer.
Do you have any idea what an amazing genius you are good Sir! I have been to my AC repair centre 2 times now and had my AC recharged both times and the guy there does not know what the problem is despite me spending some £50. I was due to go back again in the coming days and I had almost given up trying to get my AC working again. By chance (searching for W220) I saw this video. I have just been out to my car and cleared the error codes and now my AC is working again. I am so happy now/ I love you (yes its true!!) and I love the internet. Thank you, thank you so VERY much for your help and for taking the time to post this video. An amazing fix!!!!!
Hi Chris, I am glad the solution helped you, I posted these videos just to tell a friend what I had done on his car. You are right, it is amazing how the internet can bring people together. I am not a mechanic, I just love the S-Class and I work mainly on my own and friends Mercedes without any cost. Thanks again for taking the time to comment.

Hi Waqas, information like this is not available in the cars book/manual, from the dealer or from the AC guy so thanks so much again for sharing!! Take Care C-:
I hate to ask u 3 yrs. later about your A/C but this Indian genius on Utube cleared the a/c codes from the dash. Why didn't your a/c repair center also do the same???
Thank you soooo much!!! Helpful reset as we were driving during another California heatwave!!!
Thank you you saved me a trip to the dealer
It worked on my S500. Thank you soooooo... much.

Thank you very much indeed. Your information has helped me quite a lot. Of course the Mercedes service would not tell you about such simple self assistance, for obvious reasons... ;-)
Yes thank you sir I couldn't figure it out we were burning up
SUPER IMPORTANT : UN GRAND MERCI !
C’EST SUPER UTILE !👏👏👏👏👏
Thanks dear. Mine starts working
Thank you sooo much for this video.. You just saved me a bundle.. The only thing I had to do different to erase the code was to push the left Auto button back out first and then the right one.. But I'm sure that's because I have a 2001 CL500.Again, THANK YOU SO MUCH!!

Thank you so much! We replaced a compressor in a 2004 S600 and it wouldn't work after the repair (a big job to say the least). I saw this and did the reset, now it's 45 at the vents in 10 minutes on a hot day. Thanks again.

Today, I was about to follow what most people did from what I read on the internet. Most of them mentioned replacing compessor, clutch or shorting relay to engaged the clutch. I knew there's got to be a process to reset the EC light in order for the clutch to function again. Good thing I kept searching the web. Thanks to this video!! My A/C is really blowing cold air now..Saved me lots of money!!
thanking for your explenation . i am really thankful To you from the bottom of my heart. by seeing your video o have solve my problem
Thank you so much 😊
Thanks bro... u saved me 200$
Thank you so much, Great tutorial 😊
Tried this just now and it works - fantastic thanks!!
Great video, one question. Was the car running during the time of filming?
Thanks for uploading. AC works now !
What if i do that..thw air doesnt blow cold.full with freon..no codes..no ac/off light (yours has EC)? Fuse is good at the ac climate control. I have a list of nr codes... i wont list unless asked because its long. But code NR 2 list as -40, 0.
Any ideas? New compressor last year..allnew cooling (clogged radiator caused it to overheat and the freon released). Pressure valve is good though.
Thank you! Great stuff.
I Just Did Those Step And The Reset Worked,Thank You
U ARE THE MAN
thank you bro, please can you explain more for what does mean Nr:.....on the left side in the screen
and in the left side there is open or close
thanks
Thank you!!!!
You are very detail oriented. The blower on my 2005 S500 cuts it speed when I start turning the steering wheel, but it picks back up again when the car is straightened. Can you give me a clue? Thanks.
Thank you! Fixed mine in 5 minutes
You helped me so much , ac works after this 👍🏽👍🏽👍🏽👍🏽👍🏽

Why after i reset my ac follow your instruction and it works
But like after 10minute back error again,and i reset again then after 10minuter eror again,i have to reset many time especially when i go to a far place,please help whats should i do
Worked brilliantly. Thank you very much.
You are welcome. Thank you for the feedback.
Thank you so much for sharing this video. It helps a lot.
Just a question regarding the ventilation air flow.
My left grid does not flows very much air. I check it pressing Recirculation and Start bottons and there are 13 items to check.
When I check number 11 and press down selection temperature botton, the system flows air from the different air grids and left grud flows air fine, but after that, the system come back to the previous situation.
Any idea or comment?
Thank you
Maybe you'd know - the BAS and ESP notification - would that be caused by an OLD battery, or maybe a worn-out brake -light switch? - my S320 (2001 model) with 235000Km. on the odometer is showing me "ESP" and "BAS" when I get started and drive around. How do you suggest I could fix this? - the car is completely sound and has tender loving care at all times : the oil and filters are regularly renewed, etc. I would very much appreciate your response and advice.
This videos really helped me thanks
would you happen to know how to fix my radio reception? I have an 05 cl55?

That was the s*** thank you
Hi Thanks so much again as with the others no one else knew how to sort this. I watched the video and went out to my car and all sorted....unreal Going over to a friends house tomorrow to show off my new expertise on his S class!! :-))) You touched on the link for the vents and how to set them up do you have that link available?
Hi Nigel,
Thank you for your supportive comment. I am glad the video was of some help.
Regarding the vents; the climate control does not allow you set them permanently. The diagnostics is only there for testing. When you exit the menu all goes back to how the climate control software is programmed.
When you turn the values on or off, each vent opens and closes. There is also an option which opens all vents. I believe it is the one that shows like a fan icon on the display.
You can check if they all are responding or not, if not then you know there might be an issue with one of the vent servos.
Also note that different devices such as the over head control panel provide information to the climate control. For example the cabin temperature. All of this is controlled via the CANBUS network. Some of the vents do not have CANBUS integration, therefore the real test would be to open all vents and then see if all of the vents are blowing air. It is very rare that these vents go faulty. Let me know if this information helps or provide me with more information on what you wish to do with the vent positions.
Glad the video helped you.
Regards
Thank you. I did it. 🇰🇷
YANG BYUN You are welcome. Glad the notes helped.
I cant seem to get the heat to work on my S500
