Today as I was lowering the driver side window, I heard a loud pop and only the right side of the window will start to go down. I was able to close the window and tried several times with the same result; the left side of the window will not go down. The window motor seems to be working OK but something is keeping the left side of the window from moving. The loud pop suggests to me that something broke and is in the way of the left side of the window.Any thoughts on what this might be?
Thank you.
