This 2002 Chevrolet Camaro came in with the complaint that little or no air was coming from the vents but the blower seemed to work fine. I listened to the fan motor on high and could tell there was something in the fan blade. I removed the retaining pins from the passenger side lower hush panel and pulled the panel out of the car.
I unplugged the harness connector for the blower motor and removed the three mounting screws.
Pulled the blower motor out and this is what I found.

I figured there had to be more leaves so I slid my hand up into the blower hole to feel for leaves at the evaporator core. I felt a lot of leaves so I used a combination of a vacuum cleaner and a air gun with a long tip to reach up inside the box to blow the leaves loose.
This is some of the debris that was left over on the floor. There was a lot more but the vacuum cleaner was able to collect most of the debris that the air gun loosened up.
A clean blower motor and a clean evaporator core and the air flow problem was fixed. I asked the customer if they had been having a lot of sinus and respiratory problems in the family. He said that his wife has and she is the primary driver of this vehicle. Go figure, wet leaves, mold and mildew. I wonder what that causes?
