I noticed a constant squeaking noise behind my left ear when I was driving my car. It started occuring last week and its been getting worse. now all i have to do is go over small bumps or apply the throttle and the squeak occurs.

This isn't my car but the area with the red circle is where the squeak is coming from. Its where the rubber piece meets the car. I thought it was the door so I pressed it and pushed it around... nothing. So I started pressing the area where I circled and it started squeaking. I went to the other side and pressed the same area and nothing happened.



I tried pushing in the rubber piece but nothing happened. However, something felt a bit loose on the other side of the rubber piece. Like a long strip of rubber was loose. Could this be making the noise?
