crazy sound ???

407 1.6 hdi the right rear door upper floor of my vehicle has a continuous crackling sound coming from there. Something is stretching and stretching and crackling sounds. Are there anybody who has a problem like this?

Maybe the right back door comes from itself. Cracking usually comes from plastic parts.

My teacher, the sunroof, there is a vibration on the bad road and this sound is misleading as if coming from the back door. I mean, the source of the sound may be somewhere else. unfortunately these sounds are very annoying ...
