If you run your Air cond on recirculate always try using an air sanitizer in your return vent. Or switch your A/C to outside air flow for for half an hour and raise the rear of your sunroof panel to vent the stale air do this till the smell dissipates and then close he sunroof and reset the A/C to recirculate if desired.

Hints for odor of oil coming through vents

The first thing most people should do is get their manual out and find out the location of the "cabin air filter". On many cars, it is behind the glove box. This is a filter that needs changed out from time to time. If you can't find it, drive to an auto shop, ask them to sell you the filter and explain to you how to find it and change it out.
Another thing that can be done for car odor is to clean the leaves off the outside vents near base of windshield, turn on AC, select fresh air (NOT recirculate) set fan at full blast, roll down windows, and spray the outside vents on both sides with Lysol. Scotty Kilmer has a great video on YouTube showing how this is done. "Getting Rid of Stinky Car AC Odors" .

Musty odor coming from AC vents the last 2 days. Is there a filter some where that needs to be changed?

there may be a cabine filter. but if you leave the a/c in max when you leave it overnight, condensation builds and mold can form in the vents. try leave the control in a/c normal or vent. this opens the outside air door and allows fresh air to enter and dry condensation

It could possibly be the cabin air filter is clogged, especially if it has never been changed. Aside from that it is probably one of the stepper motors that adjust the various vent gates in the air passages under the dash. Although replacing the cabin air filter on this car is fairly easy, comparatively speaking, you do have to remove the glove box in order to do it.
