Odor from heater/ac on 2004 Chrysler Pacifica

My car has been on the lift for 2 days and the dealer cannot locate the cause of the odor coming from the heater/ac and can be detected by smelling the front hood for many minutes after the car is shut off.

I've heard of mice getting into the a/c system vents and dying, it is really a bad thing, not just for the little mouse. Removing the odor is very difficult. Were they able to figure it out?

Thanks for answering. They didn't see anything like that and did deodorize the a/c heater"box". I hope that's not what happened...yuck. Today for the first day in five...couldn't detect the odor. Guess I have to wait for it to return to go back for a third look. Thanks again

That's good news. I almost ran over a dead deer on the way to work today and thought of this problem you're having, maybe you ran over something? If the vehicle has a cabin filter, they should've replaced that too! Good luck, hope the smell is gone forever!

Thanks for the hints.....smell is fainter but still there....two plausible explanations. I will look into the cabin filter....have had a ton of work done on the engine, motor mounts etc in the past month. I'm ducking deer all the time but running over something tiny with an SUV is certainly a possibility. Thanks again....if it isn;t gone I'll be back looking for more good hints like yours!
