Unique Smell from Air Going Through AC Blower

[CTScott]

At this point I would pull the top of the dash off to gain access to look into the airbox to see if the evaporator is coated again (that is much easier than trying to remove the entire air box). With the dash top off you can also clean out the ducts. If the evaporator was cleaned or replaced, the ducts may still be very dirty and may be the source of the odor.

Do you notice a difference with the smell if you switch between recirculate and outside air?

I am considering your point as quoted.

Can you also please elaborate a reply from one of my Fans in FanBox Website as quoted below --- because I am not familiar with what he said as "Manifold Gaskets":

Anytime you get anything on the exhaust you will get a smell. First I would check for oil leaks around the manifold gaskets as it could be dripping on the exhaust. Check all your hoses that have air running through them and make sure they don't have any cracks or holes in them. Let me know what you find.

He is talking about the gasket between the back of the engine and the exhaust manifold (which is the metal part at the back that brings the four exhaust ports down into the one exhaust pipe).

You can certainly check all of that, as one easy way to do so is to get the car hot and open the hood and sniff around. If an exhaust leak is the cause you should smell the same smell much stronger under the hood.
