vent window frame removal?

On some Mopar vehicles the front window removal must be done a a certain sequence; i.e., roll the window all the way down. Remove all the fasteners on the divider bar so it is loose. Pull the top of the divider bar up and to the rear, until the divider bar won't go back any further. This moves the front window channel away from the window so you can remove the window. Then the divider bar can come the rest of the way out.

Again, this doesn't apply to all Mopars; just some.
