Grille assembly vent was cracked and would not stay in place nor would vent operate

By selecting the entire grille assembly vs buying just the individual parts it made the replacement simple. Just had to remove 2 screws from the old assembly to remove. The new assembly popped right in and fastened it with the 2 old screws. I would recommend purchasing the entire grille assembly vs. just the individula parts if the plastic is cracked and brittle. The price difference was not that significant.
