Had this little surprise yesterday. Started the truck and in a few seconds smoke started pouring out of the vents into the cockpit and out of the outside fresh air vents. After extinguishing, this is what I found this morning. If you have inherited or bought an old truck make sure you clean out the old leaves! Sorry for the lousy pics but I'm sure you get the point. Lucky the whole show didn't burn to the ground! Cheers!

Reason: clarification
Critters do this. Not sure if yours was a nest, but deermice are NOT cute to me anymore. They love turning air cleaners, 4 wheeler battery tops, and lawn mower engine cowlings into tinder boxes. My closest call almost cost me my previous truck. I now check often and hunt mice like the guy from "No Country for Old Men"
Blower motor resistor.
Leaves and debris fall through the cowl vent, which is why some guys use the 87 -96 (97HD) cowl vent with smaller openings. The debris will also wash down the cowl to lodge behind the kick panels in the cab. I bought an 86 cab in NC that caught on fire and burned the dash.
top left corner you can see the kick panel filled w/ debris, melted pool of squirrel cage in the bottom of housing
this squirrel cage fan is TOAST
melted rear housing
Thanks GLR. That's exactly what I found this morning. The kick panels were full of debris and had filled up the squirrel cage all the way to the resistors. Here are some more pics of the damage I found. I now obviously now am in need of a new blower motor housing. Here are some updated pics. Not pretty. Check your kick panels!
It is mounted on the side of the A/C evaporator housing next to the blower motor housing. The housing encloses both the blower motor and the evaporator.
I had that happen in my first F150 about a month after I had gotten not only the truck but my drivers license as well. The firewall and the inner fender still bear the scars to this day and that was in january of 1998. I am glad my grandfather gave me a safety kit to keep in the truck as the fire extinguisher was very handy that day
Mine was dry dirt also and used shop air to blow the dirt out.
I did not remove the rubbers so will look into that when pull the fenders for painting.
Then again the truck will not be parked under trees so how much junk will get in there?
Also when washing I would run a lot of water down the cowl to flush out any dirt that may be in there.
