hi everyone, on my x300 I have a pop noise that occurs several times when I first turn on the heat in my car. It also happeneds when I turn the heat off. I have never really noticed this before Because I dont ever use the heat but maybe a few times out of the year because I live in south Florida. Is this normal? or is something wrong?? The heat blows very hot, and have no problems with my AC either... thanks.

 

Sounds like a rotary flap sticking and releasing????
