What is the factory correct method in re-installing the Vent Window Knob, Sprint and Disc ?
From what I have read the spring goes on the inside of the door, between the vapor barrier and the back of the door card - however this creates the potential of the spring getting lodged in the hole of the door card and puncturing the vinyl.
Is the disk also supposed to be against the spring behind the door card ?
Or is there a 4th part that I am missing?
