We just got a taste of some cooler weather here in South Carolina and I had the temperature set to slightly warmer than usual and noticed an odor from the heater vents. Has anyone had this same experience and if so, what can be done about it? Thanks for any suggestions.

 

~ be sure to turn off the recirculation air button ... this will eliminate some of the moisture staying inside the system... causing the odor.

 

Try running heater all the way high for a few minutes to dry any moisture that have accumulated in the system.

 

Or replace the internal filter under the glove compartment box... that may do the trick, too.
