I noticed my air vents are starting to smell moldy when the ac is off. Anybody else experiencing this???
Interesting - where is the cabin air filter located?For some reason, the a/c system automatically defaults to fresh air mode when turned on. This requires the a/c to work much harder at trying to dry and cool the air that is coming from the vents. Eventually, the interior cabin filter gets damp and can cause this smell. The a/c should always be ran in the recirculate mode. You might want to replace the cabin filter and spray ozium or something like it into the system before installing the new filter. Hope this helps.
Usually behind the glove box. Owners manual should say. The cabin filter filters ALL air that comes through your vents. Food smells, smoke smells etc. Currently there is no quality aftermarket filter offered but the dealer offers them for around $25.Interesting - where is the cabin air filter located?
