Odor from Air Vents on 2005 Chevrolet Uplander

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
We had the deoderizor service from Chevy with no significant change. Is there anyway to vacuum out the fresh air vent lines to remove dead mouse remains?
Our fabreeze bill is getting up there.

nope, the only other answer is to remove the heater box and physically remove the dead rodent.

replace your cabin air filters located in your glove box. Once inside you'll noticed a door pull it off, behind it is an other door just open this one. you'll be surprised
Thank you and what a surprise. Our dealer,
Fitzgerald in Annapolis MD conveniently failed to do this service when they did the GM deodorizing service.
You are a good sam.
