- This video illustrates 2002 Mercedes Benz C230(W203) Kompressor HVAC common stepper problem and attempt to fix it.
This first attempt failed due to the stepper motor level failure, but still the video gives insights about the problem. I am not a mechanic btw so keep up with my slow work... :))
The second video shows how I finally fixed it in this link here:

The PDF files I promised that illustrates how to disassemble the front dash to reach stepper motors are in this link (go to post #18):

Hope this video helps some people. Give a thumbs up if this has given you any idea about the problem.
What a mess! I am so amazed about you how can disassembly and after finish your work how can assembly
In fact I congrat you for your job
Thanks lol.
Thank you for sharing the pdf file and your experience. This is very helpful. I really appreciate this video my friend. I wouldn't have known how to fix the clicking noise from my car. And it's summer so my air conditioner will not blow air thru the vents with this problem. A million thanks.

You are welcome brother. I am glad it’s helpful.
You dont have to take the dashboard off. Locate sound by touching the stepper motors. Mine was first one behind the radio.
god bless you for posting the video. this is exactly what i have done, except removing the upper dash is where i cannot find the extra screws.do you remember where they may be? I cannot remove the upper dash at the moment. by the way, when i first saw your video, i thought "HA! there must be an easier way!" to say i am humbled is a grave understatement. thank you again for posting, this is EXACTLY the problem I have. I cannot believe the heartache a clicking noise brought
Thank you lol, I am glad the video is helpful. Don't forget to see the second part.
If I am not wrong I think there were screws at the very top of the dashboard, in front of the glass, under small grills. Are those what you are looking for?
You are at super level. I can't do it. Got mine repaired by a mechanic. I think motor won't spoil if we don't meddle with airflow switch.
Yep you are right! I had to fix myself otherwise mechanic was asking me to pay more than the value of the entire car to fix it lol ;p
Thank you for the comment :D
Thank you mate for sharing your knowledge. Although I thing I have lever failure since the stepper level seems to work fine.
Very common failure indeed.
omg- That looks like a nightmare. I don't think I have the courage to do all that.... My air bag light is also on now, Would love to know how to fix that myself... Surely it would take so much work to do. Way to go for fixing it yourself though.
Hehe that was a crazy fix yeah I d agree with 'nightmare', if I knew I was gonna end up with the picture at the end...
thx for the video, i fixed the same problem as well
You are welcome 😊
Really good job , but does those step motors affect the heat blowing ? Because i dont have heat in my car
no matter go on for the best
Nice sharing my friend
Thanks.
I just went thru it just now on my W209. On mine the lever was chipped on the far left behind the HU it was sitting behind the reinforcement bar. I had to remove the wiper and the front windshield crawl to get to a bolt that holds the reinforcement bar to the firewall. It's a pain in the rear.

yeah I remember having same trouble to get behind the reinforcement bar. Glad to hear you succeeded 🙂👍
Can you do the video in how to take everything apart like you did.
Marco Arellano,
Please see the description of the video where there is a link that you can find steps of breaking parts apart in a pdf file. In that link go to thread 18 and at the bottom of that threat there are 3 links for pdf files that will help you.
Good luck!
Strong work, dude.
Was this causing one side of the ac to blow cold and the other side to blow hot?
Do you need to remove the wiper under the hood in order to access to the bolt for loosening the big metal frame supporting the entire dashboard?
Or the big metal frame can be lossen just from inside cabin?
As I remember, tbh, I cut that metal in the middle in the thin section because it was already enough of it that I spent inside and I didn't wanna go under the hood too, so I didn't really try to be smart on loosening that freaking bolt. I m not sure if it is easy to loosen it from under-hood. But you can always weld if you cut the metal; you can give it a try, if not just cut and weld it back, that was my rough solution.
Dickson Fu yes you do I just went thru it.
@@ahmadmusa55 I know this is an old thread but I'm stuck, I've just removed the dash and everything else and I've unbolted the frame but it still won't budge, I've opended the hood and removed the wiper and wiper motor, there is one bolt holding in two pipes, is that the bolt I need to release?
Do i have to remove the steering wheel to remove the upper dash board for my 2003 MB C230 coupe(CL-203).Please your view will be highly appreciated
You need to remove the steering wheel yeah, if not cut the metal that's holding the wheel (and weld it again). There was a comment about it, either in the comments of this video or the second video czcams.com/video/ex-ENAOW0qU/video.html
I d recommend you to go over comments. Good luck!
Holy fucking shit! That must have been some annoying ass clicking noise from the AC for you to do all that!! LOL!!!
Yeah it was quite a hammering kinda noise under the dash lol :D
I should probably copy this here:
I should have noted that the air bag light turned on after performing this fix because I removed the entire dash(including the passenger airbag) n I started the car to see if the stepper motors n levers are working, n at that time computer realized that there is no passenger airbag n the light/sensor turned on. The dealer said he could turn it off n he would charge me $138 n of course I didn't do that. I should probably make another video on how I turned the passenger airbag light off...
Ismail Bahadir Kuzucu how did you turn off the light?
@@elomeli211 Yes please
Well my ac blows hot+cold air suddenly, i am thinking to open the dashboard and keep the actuators hanging in cold mode; as in my country its mostly hot so do i prefer ac mode ON with no heat option. Another mechanic told me to to bypass heater core inspite of opening all dashboard. Please advice will it fix my issue?
Though to answer without knowing what the problem is. I am not sure if the heater and compressor can work at the same time, I d first guess your compressor may not be working properly. Then maybe check if you have enough freeon on the line and check the pressure is right, if you haven't.
@@ibaha411 Well the ac blows cold air that means the compressor is fine! Even checked the pressure. But my question is if i bypass the heater core will the hot blowing air stop. Secondly, will it have any advance effect on the AC unit!
try making a new dash with clear plastic so everyone can see the wiring!
........WOW!!!!
Lol did he say this bitch
Yes he did that car pissed him off for sure 🤣🤣💯
Are all 6 stepper motors the same ???
Chulla Quiteno sorry just seeing your message, I normally try to answer any question posted... answer to your question is yes, in this model they are all the same.
What happens if I don't fix this?
Clicking every 2 seconds on the dashboard.
Omg
LOL. WHAT THE HELLZ
All thay for one plastic part
Exactly, stupid little plastic part. I think they stopped using those poor parts a few years later.
bad camera!!!
It is damn iphone, sorry I don't have a prof cam :(
