Thanks for replies guys.
Pcmaher: great link. I will try to pull some codes out of it.
MB Doc: Actually my "rest" function does not work well. Also heat was not Hot, rather very warm but not Hot as my friends c43amg. I was suspecting my aux heater pump but I didn't know that shorting pump can cause for the whole climate control to fail. Will try to check it.
