Mercedes Benz W220 Climate Control Diagnostic

In the Mercedes Benz W220, W215, S-class, the air conditioning and heating are controlled through the Automatic Climate Control (ACC); this procedure can diagnose many problems directly through your unit. This video will show you how to read the fault codes on the W220 climate control unit and clear them.

The air conditioner, Automatic Climate Control (ACC) on the Mercedes-Benz W220 S-Class and W215 CL-Class, can be troubleshot by accessing the hidden menu. This article will show you how to access the hidden menus to stream live data from ECU and read, reset and clear air conditioner fault codes.

I just wanna thank you for this video ❤️, my 03 S500 had this issue for 4 years and I gave up but saw this video and followed your steps. I almost cried when I saw that AC off light switch. I’ve had to drive in 108 degree California weather without my AC. Thank you a thousand times man . Defiantly following your channel

Very good video and easy to understand. My Dad has a 2004 s430 and he's saying the AC red light remains on, which means the AC is off. And he says the AC won't turn on, red light remains solid on. I'm going to follow your instructions to get the error codes and maybe try clearing them too. I suspect it might be running low on AC fluid and need recharging, but he says if that were it then the red light is supposed to flash meaning it is low, but it's not flashing it is solid, the red light just won't turn off.

My ac is only blowing hot air, imma try this and I'll let you know how it goes, thanks for the video man

[curlymyhero]

Thx this trick works good! In a few days I'll read my scan tool and c what other codes come back.

Thank you so much for this! My EC light was stuck on which caused warm air to constantly come through my 2000 s430. I followed your instructions and erased the error code within a couple minutes. Air is cold flowing now that the EC button light isn’t stuck on any more!

[gillesbaillargeon]

Worked perfectly! Thank you so much!!!

hello. my ac is blowing hot air and it was fine last night. i did what you said and i have no errors. my ac doesn’t seem to be powering on but i don’t know bc the ac off button is still off

[David-zvem]

Hi can you show how the different settings of those two push buttons work? It’s so confusing what each setting does. My car is 2002 s55 amg. Thanks.

[tannerhurd]

So I have no ac codes the compressor is kicking on and there is condensation under the car but the code air won’t blow inside the car any ideas?

[roomthree]

My 2002 S500 is having this strange problem where the air will randomly cut on by itself intermittently and then cut off; out the rear vents. While my car is turned off.

Have a 2001 s500 mercedes benz a/c runs for a while then just stops blowing but buttons remains on . just doesn't blow then i wait a little with a/c off then it starts again after. While shuts off again blowing..What could be the issue everything else points to a blower regulator?

[zaharosu]

Hi on my S350, when on auto, A/C on there is cool air blowing from central vents but right hand side (driver side as is UK model) blows hot air? Also how to adjust temperature that blow on down side of car
Thank you
