Burnt popcorn smell and smoke from defrost vent

[blanktoom]

I searched and found a thread seeing a bloated burnt popcorn smell and smoke coming out of the defrost port of a inventory 83 911SC Targa. I spent ripping aside the HVAC system up front to watch in the ducting and what's clean. I'd find in the surrounding regions several very small evidence of pine tree seeds which were probably deposited by a bark. But because I've smoke billowing in the skillet, I understand that I have high heat inducing something to burn off. That type of heat come in the heat exchangers if I am thinking correctly. I managed to check within the driver's side heat exchanger and it was very clean. I couldn't remove the passenger side due to the oil line at the manner. Incidentally, the smoke is coming mostly in the passenger side defrost port. Any ideas on which the smoke causing debris may be? Might it be feasible for creatures to get within the heat exchangers?

yes of course they can , all kinds of rodents can get in there .. But i would ask if you have your dash blower motor going , that can also fry and produce smoke as it is not fused.. if you are running heat only i would suspect a nesting rodent in your exchangers.

Rodents will stash dog food, corn, or any other edible item under your shroud. Prolly a good idea to use a bore scope and take a look. OR if you have top of the motor oil leaks this would be a good time to pull the intake and shroud and investigate the "Triangle of Death"....

does the blower behind the dash still work? very common for those to get clogged up or dry bushings and fry the brushes. Also pull out the gauges and check for burnt up wires. Some circuits are unfused and can cause major damage. There is a writeup somewhere on the forum of where to add fuses
