3 Answers


What kind of odor? Oil smell, musty stale air smell, mold? Can you pinpoint where it is coming from or just all over? Maybe the A/C drain is plugged and you've got an odor from the heat assembly. Need more information.


Cabin or air filter? Cabin filters should be changed every 15K, Air filters a little more.


i usually put pine sol or the equivalent down the vent area at the firewall with the fan on full getting outside air. u need to clean out the mold.
