it could verywell be a dead mouse inside the freshair box. the other smell could also be your heater core needs replaceing and that is steam you see.in any case the box has to come out to do this so what ever is in there can be cleaned out :x

last reply is on the the right track about both problems you might want to check the carpet on the passenger side floor you will have to remove kick panel and pull up carpet look for damp carpet and padding (if Damp spray with half cup water and half cup clorox ) to check for dead animal try removing blower (Evap) under dash turn on truck then turn on blower to locate should be 6---5/16" screws pull down may be tricky take a flashlight and a womens compact mirror and look around before you close spray with same bleach and water mixture if not problem try to find out if you have a fresh air filter much like your a/c at home this filters outside air try replacing this bout 4-6 dollars
let me know what you find there are a couple more things you try

Suggested Repair

Inspect the passenger-side carpet and padding for coolant dampness. A leaking heater core can cause antifreeze odor, steam, and loss of coolant and usually requires removing the HVAC box to replace it. While the box or blower is out, look for a dead animal, clean the area, and replace the cabin air filter if equipped.

Conversation Summary

The owner of a Ford Expedition reported a strong AC odor, vapor that looked like smoke, an antifreeze smell, heavy leaking underneath, and an empty coolant reservoir, after an earlier fishy smell. Replies suggested a dead animal in the fresh-air or HVAC box and a failed heater core producing steam. They advised checking the passenger carpet, inspecting around the blower, cleaning any contamination, and replacing the cabin filter.
