I am sure the topic sounds stupid. But I had my coolant flange, and temp sensor replaced a few days ago, and ever since then I have not noticed the little snowflake by the outside temp gauge in the dash come on when it is cold outside (has been -5 to +20 the past week).

I just could have sworn I remember it coming on when it was cold. And am curious if now that it is not coming on if something is "wrong".
