Burning leaves

My first experience with that was more of a camp fire smell. Thought someone was burning leaves that fall, but when I looked around I discovered that no fires were within a couple of miles. It was the truck - although not quite on fire it was smoldering. Not what I'd call an air freshener.

I was lucky since I'd read about this problem here on FTE before it happened. So when I smelled smoke I quickly turned the heater off and things cooled down, (the motor cooled down, and that's when I heard the highway sound).
But, I went through a mental checklist as I was doing it that went like this: I could turn the blower to High and bypass the resistors, but if the fire is already started that would fan the flames, literally. Or, I could turn it to Low, but that puts more resistance in the circuit and makes the resistor hotter. Hmmm, I wonder if one of the middle speeds would be best - less heat in the resistor and more air flow to cool the resistor.
In the end I realized that this analysis process was ...... stupid, and the best approach was to turn the blower off as quickly as is possible.

Weather warmed up enough today to work the issue. Removed the blower and saw no leaves. Removed the resistor pak and saw about 4 little leaves with some dust. Felt some packed dust at the front of the evaporator, so I make a 'pick' from a #10cu wire and loosened what I could then vacuumed out the case as best I could. Once the blower was out I could see my 'fix' from long ago was still in place. Nothing but very small bit/pieces could get by it, so where the few leaves were from, might have been from the 1996 evaporator replacement. My fix was installed after that work. Did not take the case apart and did blow out the ducting.
The pinhole cover might arrive tomorrow. I'll need to repaint it but no hurry. Made a cover from ¼" mesh screen, plasticized it and attached it with small black cable ties. Almost invisible even though it's on the outside of the cowl.
