I am better with words than mechanical. Paul, I hope you don't mind.

From above:
We've been installing these for well over 25 years without these issues.

The Precision rubber beltline glass scraper is a consistent width from front to back so contact of glass with the rubber should be the same from front to back. If it is not, then the door gap isn't consistent.

The same is true for the inner felt flocked beltlines.

Things you should check:

1. The strap under the vent assembly. (Not covered here.)

2. Is the door glass opening a width consistent from front to rear? If not, this needs to be corrected.

3. When installing, you should examine the metal that the beltline fastens onto. The clips go through small holes. More often than not, when removing the old beltlines, some distortion may have occurred. Most folks aren't aware, but you should insert a small blade trim tool into the clip to unfasten the old beltline without distorting the hole that the new beltline clip fastens into. On the inner and outer door edge where they fasten, this distortion from the bends in that area can push or pull beltlines in or outward. A lot of people just pry the old beltlines off and it distorts mounting tab holes.

4. Another item to check also is the angle that the metal lip / metal flange that protrudes down into door that these new beltlines fasten to. These quite often get bent inward or outward slightly. If the angles are off you have issues with the beltline.

5. Again, the most common cause of this issue is prying (manhandling) beltlines off to replace with new. (See item 3 above).

6. Sometimes, we have seen the old door glass sash rusty and swollen. This rusty, swollen condition causes it to catch old beltlines when the window is rolled up completely causing them to pry beltlines off since they catch them so badly.

Thanks, I'm much more comfortable with tools than a keyboard.
