w209 heater problem

Hello
I have a w209 2006 (facelift) model and suddenly heater started to blow only hot air
I have manged to read sensors pushing rest button long and it seems that internal temperature sensor (01) is reading 0 celsius
Is there anybody to know how to read fault code and delete that fault ?
I mention that on my ac dashboard i don't have EC button
Other than that i have read this https://www.benzworld.org/forums/w22...lp-c-diag.html
I wonder if this will apply to CLK and if the thermistor is tha same?
Thank you

Please take a moment to visit the User Control Panel and update your profile to include your car model and year, and your location (at least country). This information will then appear below your name and avatar on the left side panel next to each post you make. This will greatly help others to give you better information. If you are using the mobile version of the site, you will need to switch to the "full" version to get to the User Control Panel.

Yes, it's probably the sensor in the OCP.. One way you can test it is to open the sunroof and windows (or the top, if a cabriolet) This cause the ACC to ignore the sensor int he OCP. If that's it, then here's the fix:

Hello, I have updated my profile
Also my car is not convertible and it doesn't have sunroof, i have tried to open windows but it doesn't seems to affect ACC
Do you know if it's possible to read fault codes from ACC display due to the fact that i don't have EC button or i need STAR for this?
Thank you

Yes, you can read fault comes from the the ACC with a proper tool. Of course SDS (Star) does this, but there are some others that will read MBZ's systems. The Autel MD802 Elite, and the iCarsoft i980 or MBII are all options.
