When I have the heater on full blast at 85 degrees(digital climate), after a while it starts to smell like it is burning. How to fix?

 

"tastes like burning" - Ralph Wiggum

 

i wondered if i was the only maxima that did that...

 

Clean the vents? Set to normal temps like 72-74?

 

probably that black foam crap that they use to insulate it. after a while it gets brittle and breaks off and falls back further into the vents and cooks. this happened on my 96. i tried to vaccuum it out as best i could.
