Without hearing it, I can't help you. What kind of pop was it? Metallic? Plasticky? Hollow or solid?
You say it's winter there so there might be some slight freezing in the engine compartment and this popping sound could be related...[?]
The flaps on mine sound like air is hissing out, not any popping or whatever. The only popping sound is when the ACC cycles its blower speeds, but it's negligible.
