I have this exact same problem. When the car has been sitting in the hot sun and when the AC kicks on the popping occurs. It happens when hitting bumps or any vibration within the car. I was able to isolate the problem and interestingly enough, when you push on the material on the pillars on either side of the windshield the popping or cracking sound is actually coming out of the small tweeter speakers above the windows. I couldn't believe it at first. It happens more so on the right side then left. When the AC is on all i have to do is push on the material on the pillars and i get a consistent popping. As others have said once temperatures stabilizes it goes away. This gets me thinking that the speaker wire connection may either be loose and the draw of the AC may be causing an electrical phenomenon so when the wire is disturbed it sending popping or a rattle sound out of the speaker. I don't believe the speaker itself is loose since the sound actually sounds like a sound coming from the speaker itself sort of like when you plug in a microphone to an amp. I'll continue to search forums online to see if anyone else has this issue.
