Thanks for your help. I would like to have the temperature regulation during the winter season. Too hot is not pleasure inside the cabin. No warm air my passenger will be freezing to dead.

I was disappointed my local MB dealer. They charged me the diagnostic fee and gave me the wrong information. I was lucky that I did not let them replace my CC unit. The dealer repair cost is over two grants. I will have to eat the wrong repair money. Hopefully, I can find out the problem soon.
