Hi there!
Last summer I repaired my AC & climate control unit, taking a part two of them and fixing all best parts in one box.
Don't ask me how I did it, but I did!! It was rather difficult, but It was impossible to find the right one for the W208.
Now, everything is working correctly, but the command for the rear defog is not coming out of the unit.

COULD ANYBODY TELL ME WHERE I CAN FIND THE RELAY FOR THE WINDOW HEATING?

This way, I can easily make an extra switch for the defrost of my rear window.
Thank you for his information!!
