Door glass question

[Richard Cranium]

On the stainless steel channel on the rear of the door glass, there is a wedge shaped plastic slide with a spring attached. On mine, the spring is broken. What’s the purpose of the plastic piece being able to slide up & down a half inch and is the spring really necessary?

Thanks.

What I'm amazed at is, somebody beat RC to the same thread topic before he did ! Is hell now freezing over ?
