No matter the air temperature or fan speed, there's some bad smell coming from the vents whenever I have my heater on. It kind of smells like burning plastic, but not that bad, and I haven't seen any indication of melting or burning anywhere else, but I haven't looked deep and thoroughly yet. I'm guessing it's just the air filter that needs replacing, but might it be the heating element or something?
