Hope Digger doesn't mind. I copied this from LOST.
"OK there is not a tsb for this problem, however Chrysler did update the close out panel with a new version. The poor airflow to the drivers floor is caused by the poorly designed closeout panel. The panel is supposed to direct airflow to the floor, but there's two problems with it. One is the design doesn't direct the air properly and the material is too flimsy. This caused most of the air to be caught above the closeout panel. Not very effective.
Here's the part number for the new closeout panel for the poor airflow on the drivers side floor: 55197311AE "
Lovin' my CARBON FOOT PRINT!
