what is popping sound

What is your question?

when I turn on my heat in the mornings, theres a loud clicking/popping sound on right side inside of car. this just started, its usually in the mornings, its cold, and I was thinking maybe im not letting the car warm up enough before turning on the heat, not sure.. but it does it, then after I start driving, and turn it back on , it doesn't do it anymore
