Mouse smell from vents

[spuz]

Grill by wiper. There is drain hole on both sides. The water enters the grill and exits via two drains under grill. The water exits at bottom of truck. Exit hole Too small for mice.

Finally figured it out. There are two drain holes under the grill. Mice can get through drain holes.
These holes are the drain entrance. The exit at bottom of frame is too small for mice. The entrance dies have rubber doors. One was missing. I don't know if these doors would stop mice. In all there are six ways mice could get under grill. Two drains, two wipers and two upper corners. The mice were coming back and this is why smell continued.
You should keep your ac on recirculation as that closes doors to outside. Mice still can get six inches down. I blocked drains with mesh. Reglued
The wiper hole rubber flap and stuffed tin foil in corner holes. Also put screen over engine air intake.
Searched and never got anything approaching an answer. Dodge community disappoints again.

Thank you this helps !
