Been on this forum for almost a year, first post ... So I just picked up a 08 STL.

I noticed that it doesn't get a lot of airflow out of the vents or floor. I initially thought that it was door actuators. I checked the vacuum at all of them and they all cycled as required.

I also checked the blend door, and the fresh air doors as well. They all cycled as desired. When I was checking my fresh air door with the borescope, I noticed a layer of... insulation maybe? on top of the inlet for the blower. So I removed the blower, and the picture below is looking up into the housing. Is that supposed to be there? It appears extremely dense, so I am led to believe thats what is causing my flow issues.

If it does not belong, any ideas on how to remove it? Where is the fresh air inlet on this thing?

kind of looks like a mouse nest built out of carpet fibers.

 

The sport trac doesn't have carpet... So is it safe to say that doesnt belong lol

 

looking at the photo it actually looks like it was original, but im trying to figure out what purpose it could serve. You should be able to figure out the flow path of the air. Sure looks like it would go thru that hole... I would be looking for a way to get it out and test.

 

here is another idea? or at least access to the inside ?
