Condensation may develop in the heater case which can cause a musty odor from the heating, ventilation and AC (HVAC) system. Our technicians tell us a cleaner is available for the heater case. Also, the drain system should be checked for debris.

awful smell from heater and AC at any speed. odor leaves when the car has been on for a while but eventually returns. I have to get it checked out and will come back with an answer.
It has not been fixed... I'm glad I found this. They changed the filter and it went away but than it came back a little bit after that.

Horribly musty, "bad rag" odor coming from vents when turning on AC. It doesn't seem to stink when I use the heater, just the AC. It's awful.
