Default Buzzing sound from seatbelt

2008 Chevy Trailblazer

Just started hearing a buzzing sound right behind me, the sound continued even after I turned the vehicle off and removed the key . Sounded like it was in or near the door. Upon inspection, and accidentally found out when I removed the key and stepped out, but I pulled my seatbelt out, and the noise stopped, let it roll back in, and it sound started again. Repeated this 8-10 times, same result. What would make this buzzing sound in the seatbelt, when it is all the way pushed back in, and stop when it is pulled out and extended? Any idea? Any help would be greatly appreciated.

sounds like the pretensioner is malfunctioning or the plug came loose.
