Hi i have an issue with climate control, on the passenger side (right one both back and front) it is blowing cold .. and from time to time on the left side as well. There is no fault codes

 

If you have the 3 or 4 zone system, there are separate temperature settings for the driver, passenger and rear seats.

 

😃😃 i have the issue with the system at all, i know that i can set the temperature but it is blowing cold anytime

 

Can you take a picture of your settings? Unless you have a hybrid, heat is normally not a problem with an ICE car's HVAC. I don't live in a cold climate, but even when temps are in the 50s my W213 gets toasty fairly quickly.
